In the section to the question, explain what homogeneous subjects are, please give an example. given by the author Irina Osadchaya the best answer is This is when there are 2 subjects in a sentence, either separated by a comma or through a conjunction and. For example. Masha and Sasha went to the park. Sasha and Masha are homogeneous subjects.

Here's an example: Clay and leaves complete the construction.
Reply from Anastasia Trufanova[newbie]
Masha and Sasha are not the same! Example: Masha was picking mushrooms, berries, and leaves.
Homogeneous members this is when there are 2 or more words that are connected to one, they are connected by a conjunction or commas. I gave an example of homogeneous subjects

For example: I drew a rocket, an airplane and a mother.
Reply from MetalRocks[newbie]
Masha and Sasha walked into the forest;
You and your interlocutor are right;
Mom and daughter are preparing lunch, etc.
Reply from Alexey Maltsev[active]
Masha and Sasha went to the park - a very correct example!
Your listings (Masha collected mushrooms, berries, leaves) are homogeneous ADDITIONS. The subject here is MASHA and the predicate COLLECTED. Mushrooms and berries are homogeneous additions expressed by a noun.
SUBJECT refers to the predicate; it is an independent part of speech. Homogeneous subjects refer to ONE predicate.
Sentences with homogeneous members are those sentences in which there are two or more members of the sentence that answer the same question, are interconnected by the type of coordinating connection and relate to the same member of the sentence.
In a sentence with homogeneous members there can be two or more subjects with one predicate, two or more predicates with one subject, several minor members sentences dependent on one of the members of the sentence.
Sentences with homogeneous subjects
With homogeneous subjects, the predicate is in the plural. If homogeneous subjects are combined using an interrogative particle -gu, -ku, -ӈу, then the predicate is in the form singular.
Munӈidu tatkittuvun asatkar, beetker umukendu tatchara. At our school, boys and girls study together. Oron-ӈу, ӈinakin-ӈу imannadu koӈloderon? Is it a deer or a dog turning black in the snow? Etyrken, atyrkan bidechetyn. There lived an old man and an old woman.

There is a lot of such grass in the taiga, on the hills and on the banks of rivers. Nuan okin-da himat, ayat dukudyavki. He always writes quickly and well.
Each of the homogeneous members of the sentence can have explanatory words. Most often, explanatory words have homogeneous predicates.
January 29, 2015Tar hunat akinmi tetygelven tetten, akinmi murinman eriren. That girl put on her brother's clothes and called her brother's horse. Nuartyn ororvor inilvetyn gara, dyula ire.

Dyalvi biraӈmar daptudun bidechel, beyurve vadechal. Relatives lived at the mouth of the river, killing animals.
In order to make it easier to convey to the listener the meaning of what was said, homogeneous members of the sentence are used in the Russian language. Compare: “The shady forest calls to the traveler. The shady forest beckons the traveler. The shady forest promises coolness.” Or the same thing, but presented in one sentence: “The shady forest calls, beckons the traveler and promises coolness.”
A sentence with homogeneous predicates, examples of which you will see in this article, helps to simplify the semantic load, while eliminating the need to pile up several syntactic structures in the text.
Features of the composition of simple sentences
You probably know what simple sentences differ from complex ones. The first ones have only one grammatical basis, which usually includes a subject and a predicate (or one of these members). And complex sentences There may be two or more such bases.
But in addition to the above-mentioned ways of expressing thoughts in the Russian language, there are also so-called complicated constructions. That is, those that include, for example, homogeneous members. This means that a simple sentence with homogeneous predicates “This lecture is interesting and informative” is not entirely simple. In Russian grammar it will be considered complicated.
By the way, there is still a complication introductory words or proposals, as well as isolations, appeals, etc. We will focus on the first version of complicated constructions. 
Basic signs of homogeneity for members of a sentence
But before we start discussing homogeneous subjects and predicates, let's remember general rules, relating to all members of the sentence.
The main sign of homogeneity for both the main and secondary members of any sentence is that in this construction they will be equal, performing one syntactic function, referring to one member in the sentence and, accordingly, answering the same question.
Between them, regardless of the part of speech, there is either a coordinating or non-union syntactic connection, emphasizing their equality. The first is expressed, as a rule, using the intonation of listing and coordinating conjunctions, and non-union connection is expressed only intonationally.

What predicates can be homogeneous
Both the minor members, the subject and the predicate in the Russian language, becoming homogeneous, can nevertheless have dependent words (however, the same applies to the minor members). For example: “The girl looked out the window and sighed.” In this sentence there are two homogeneous predicates (looked and sighed), but the first of them is extended by an addition (to the window), and the second has no dependent words.
Most often, all homogeneous members of a sentence - predicate, subject or others - belong to one part of speech, but there are also constructions in which they can belong to different grammatical classes, expressed by phraseological units or phrases.
For example, in the sentence “Andrey joked and laughed to tears,” the predicates are expressed by a verb (joked) and a phraseological phrase (laughed to tears), which does not prevent them from being homogeneous. 
How a series of homogeneous members is grammatically arranged
To grammatically combine homogeneous members in a sentence, both enumerative intonation and conjunctions are used. The latter can be connective (and, yes), adversative (a, but), and also divisive (or, or). In the example “She’s either talking on the phone or running to her friends” main member sentences - predicate - connected by the disjunctive conjunction “or”. And in the example: “This boy is small, but smart,” they are connected by the adversative conjunction “but.”
Comma between homogeneous subjects and predicates
The main punctuation rule when writing homogeneous members of a sentence is that in the absence of conjunctions, a comma is placed between them. Homogeneous predicates are no exception. Examples “The rain whispered, lulled, evoked languor”, “Under the sun the drops sparkled, shimmered and seemed silver” confirm this.
But notice that in the second sentence, between two of the three predicates there is a coordinating conjunction “and”, which eliminates the comma. True, this is only possible if it is not repeated, otherwise you will have to pay attention to the subtleties. 
When to use a comma in sentences with repeated conjunctions
In the construction “And his hands, and his face, and his clothes were covered with a thick layer of soot,” homogeneous subjects are connected by a repeated conjunction “and,” and this case already requires a comma to be placed between them.
In a situation where a union breaks homogeneous members into semantic pairs, each of them is taken as a single component from a homogeneous series: “Squeals and screams, laughter and the stomping of feet were heard through the open window and beckoned into the courtyard.”
Please note that homogeneous subjects and predicates in this construction are connected in different ways: the subjects “squealing and screaming”, “laughter and stomping” are collected in pairs, and there is a comma between them. And between the predicates “were heard” and “beckoned” there is a coordinating conjunction, so a comma is not needed there.
A comma is also placed in sentences where homogeneous members are connected by so-called double conjunctions (not only..., but also...; not so much... as...; if not..., then..., etc.).
Please note that in the sentence “Snow covered not only the lawn in front of the house, but also hung on the trees with a white blanket” and similar ones, the comma in the double conjunction is placed before its second part. 
Comma in sentences with several rows of homogeneous members
A sentence with homogeneous predicates (you can see examples in the article) in some cases has several rows of homogeneous members. They need to be distinguished from constructions where there is only one such row, and repeating conjunctions between homogeneous members.
In the sentence “In this house a cat and a dog lived peacefully and did not quarrel” there are 2 rows of homogeneous members (the subjects are “the cat and the dog”, as well as the predicates “they lived and did not quarrel”). They are united in pairs by the connecting conjunction “and”, which means that a comma is not used in this construction.
Sentences with homogeneous predicates: examples of colons for the main members of a sentence
A number of homogeneous members of a sentence, regardless of the part of speech by which they are expressed, may have words that have a general meaning and are equally related to each lexical unit from this series. For example, in the sentence “Fruits were piled on the counter in bright heaps: apples, pears, plums and peaches,” the generalizing word “fruit” carries a generic concept.
If a simple sentence with homogeneous predicates or other members of the sentence includes a generalizing word, a colon is placed after it. When reading, as a rule, there is a pause at this point: “Mom managed to do everything: cook dinner, do the laundry, wipe the dust and sing songs.”
By the way, the generalizing word always turns out to be the same member of the sentence as the homogeneous members associated with it, since they have the same syntactic function.
Examples of dashes for main parts of a sentence
If a homogeneous series ends with a generalizing word, then it is separated by a dash: “Milk, berries, and mushrooms - everything in the village seemed especially tasty.” “Her thin hands, curls at her temples, even the flowers on her dress - everything aroused delight and seemed beautiful” - homogeneous predicates here are separated from homogeneous subjects with a dash, since they are followed by a generalizing word.
Together with a generalizing word, an introductory word can also be used (that is, in one word, namely, somehow, etc.), then a comma is placed between them: “No fleeting glances, no sudden blush, no sighs - in a word, nothing did not escape his attentive eyes.”
Some cases when a dash is placed
A dash for homogeneous members can appear not only in the case of enumeration. So, if homogeneous predicates carry a sharp semantic opposition of one in relation to another or a sudden addition, a dash is placed between them: “I went out into the garden - and froze when I saw a squirrel on the roof of the gazebo.” The dash in such sentences emphasizes the surprise, the suddenness of the action: “The prince met Cinderella and immediately fell in love with her.” 
By the way, if homogeneous members do not have unions with each other, but at the same time express opposition, they are also separated by a dash: “He is light - he is darkness, he is faith - he is unbelief.”
How to recognize heterogeneous and homogeneous predicates: examples
If words are used in a sentence to emphasize the multiplicity of objects, the duration of an action or its repetition, such members of the sentence belong to homogeneous ones.
Please note: “We sailed, sailed, sailed in a thick, impenetrable fog.” The predicate in the Russian language in this construction is considered as a single member of the sentence.
Members and parts cannot be homogeneous compound predicate, which is expressed by a combination of verbs (I’ll go and rest, let me look, I’ll take it and complain, etc.). A construction with them cannot be considered as a sentence with homogeneous predicates.
Examples of sentences with phraseological units (neither give nor take, neither fish nor fowl, and laughter and sin, etc.) are classified according to the same criteria.
S I N T A X I C H E N O R M S
C O R D I N A T I O N
Mn. h Unit h
1. Animation 1. Inanimate
2. Active action 2. Inactive action
3. Direct word order 3. Inversion
4. Words: only, only, row,
part, 1, 100, 1000, 1000000,
a lot, a bunch, etc.
There are several types of connections in the Russian language: coordination, coordination, control and adjacency. For each of these types there are some features of syntactic connection.
The grammatical connection of the main members of a sentence is called coordination. They can join different words, and their morphological properties do not necessarily correspond to each other. When coordinating the main members of a sentence, the problem of choosing the forms of the number of the predicate arises, when the subject indicates many objects, but appears in the form of a singular number.
I. The subject is expressed by the collective nouns majority, minority, set, row, part, several
The predicate is placed in singular, If:
1. The subject is expressed by an inanimate noun: Some of the chairs were in the corridor.
2. Activity is not emphasized characters: Some of the food supplies were in the warehouse.
3. The predicate is expressed by the passive participle: Most of the books have been republished.
4. Subjects have words just, just, only: Only a portion of the students passed the interview.
The predicate is placed in plural, If:
1. The subject is expressed by an animate noun: Most of the employees went on vacation.
2. The subject has a dependent word, participle phrase or subordinate clause with the word “which” in the plural: Most houses built in recent years, designed by young architects.
3. The sentence contains homogeneous predicates or subjects: Several workers, engineers, and employees of our plant have passed qualification certification.
4. The predicate in a sentence is a compound nominal: Some of the reports at the conference were interesting.
5. The predicate of an inanimate noun emphasizes the activity of the action: Most of the meeting participants have already spoken.
II. The subject is expressed by a quantitative-nominal combination:
The predicate is put in the singular, If:
1. A compound numeral ends in “one”: One hundred and seventy-one scientists registered to participate in the conference.
2. The nouns are accompanied by the words “years”, “months”, “days”, “hours”: Several years have passed.
3. The subject is expressed by the words “pair”, “three”, “ten”, “dozen”, “hundred”, “thousand”, “million”, “billion”, “mass”, etc.: A million viewers watched the film "Day Watch".
4. With the subject there are the words “total”, “only”, “only”: Only several students passed the test.
5. The subject contains a numeral floor- : Half the city took part in the celebration.
6. With a subject with numerals 2,3,4 denoting inanimate object: Three pencils lay on the table.
The predicate is placed in plural, If:
1. The subject group contains combinations of “two”, “three”, “four” with nouns feminine: There were four birch trees on the site.
2. With the subject there are the words “all”, “these”, “some”: Some 500 rubles are not considered a high price for this thing.
3. With a subject denoting an animate object: Three students received straight A's.
Fluctuations in coordination by number are observed in the following cases:
1. When designating quantities over four, because when designating large quantity objects or people they are perceived as one whole: 137 delegates have already registered - have registered.
2. When indicating an approximate number: from 1 to 157 families received - received housing.
III. Homogeneous subjects.
1. The predicate is put in the plural if direct word order is used and the predicate comes after homogeneous subjects: His calmness and simplicity of manner surprised those around him.
2. If there is inversion in a sentence, then the singular form is used: There was stomping and screaming in the village.
3. If the predicate denotes an active action performed by a group of people, then, regardless of position, it is put in the form plural: And in the evening, employees and friends came to them.
4. The choice of predicate number forms is also determined by what conjunctions connect homogeneous subjects:
1) If homogeneous subjects are connected by connecting conjunctions and, yes in the meaning " And "or there is a non-union connection between them, then with direct word order the predicate is put in the plural form, and with inversion - in the singular form.
2) If homogeneous subjects are connected by dividing conjunctions or, whether, or as well as the union neither this nor that , then the predicate is usually put in the singular form and agrees with the last subject: What appeared on his face was either fear, or melancholy and annoyance. However, if the predicate is in the past tense or expressed by a passive participle or predicative adjective, and the subject is in words of various kinds, then the plural form is used.
Homogeneous members of a sentence are those members that perform the same syntactic function and answer the same question. They can be both main (subject, predicate) and secondary (definition, object, adverbial) members of the sentence.
Homogeneous main members of a sentence
- subjects (perform the same action), for example:
My cousins and my sister constantly quarreled as children, but now they support each other in everything. Homogeneous subjects: brother, sister.
Trees, roads, houses, bridges, rivers - everything was covered with white snow with the arrival of winter. Homogeneous subjects: trees, roads, houses, bridges, rivers.
Apple trees, pears, plums and apricots grow in our garden. Homogeneous subjects: apple trees, pears, plums, apricots.
Dogs and cats are my pets and are always happy to see me back. Homogeneous subjects: dogs, cats.
Mathematics and computer science turned out to be school subjects that were very useful to him at university. Homogeneous subjects: mathematics, computer science.
Tulips, chrysanthemums and cornflowers are very delicate and beautiful flowers. Homogeneous subjects: tulips, chrysanthemums, cornflowers.
- predicates (denote the action of one object or living creature), for example:
Today in class English language the children read and translated the story. Homogeneous predicates: read, translated.
Homogeneous minor members of the sentence
The main characteristic of homogeneous secondary members of a sentence is their dependence on the same word.
- definitions (characterize an object from the same side), for example:
Red and black laptops of the same model were delivered to the online store. Homogeneous definitions: red, black.
- additions (located in one case), for example:
From the window he saw the sky, the sun, trees, birds. Homogeneous additions: sky, sun, trees, birds.
- circumstances (can be expressed by a preposition and a noun), for example:
There was paint everywhere: on the window, on the table, and even on the ceiling. Homogeneous circumstances: on the window, on the table, on the ceiling.
