You are Sohini/ Sohan, a volunteer member of "Apna Sapna NGO", 32 Cook Town, Bengaluru. You offer your services regularly to a g
koban [17]

Answer:

32 Cook Town,

Bengaluru.

25th March 2021

Dear sir/ madam,

My name is Sohini, and I am a volunteer member of "Apna Sapna NGO" As a volunteer, I offer my services to a government school in the neighborhood. This letter aims to raise awareness about the despicable condition of the school. Also, suggest methods to improve it.

The school's roof is damaged. It has holes on it, and water or birds enter through these holes. When it rains, the students can not have the class, and when birds enter the classroom, they get distracted very easily. Besides, small ceiling pieces are falling on the heads of teachers and students. This can be very dangerous since a  portion of the ceiling could fall and kill someone.

Another unacceptable condition of the school is its dirtiness. The bathrooms, cafeteria, and some classrooms have a horrid smell. Besides, there is litter accumulated in the bins for weeks. This lack of disinfection and cleaning can attract rats, cockroaches, or illnesses in the students and teachers.

To solve these problems and give these kids the education that they deserve, it would be a good idea to organize a festival to raise money to repair the school or ask big companies to donate money. Concerning the school's cleaning, the school could create a cleaning project where they teach kids to keep the school clean and have groups to do different cleaning tasks every day.

I hope that you could help the school by publishing an article about it.

Yours faithfully.

Sohini.

Explanation:

In a letter to an editor, we should use the formal language since we do not know the person. Also, we should ask in a polite way for things.

In the first paragraph, we introduce ourselves and why we are writing.

In the following paragraphs, we describe the school's problems. We can also use one paragraph for all the problems instead of multiple ones.

In the fourth paragraph, we write methods and suggestions to improve the school.

Lastly, we write a closing line, and we finish with the phrase yours faithfully since we do not know the reader's name. If we know the reader's name, we start the letter with dear and the name and end it with regards, or sincerely.

Explain the role of chromosomes, DNA and genes in the formation of phenotypes in an organism.
irina [24]

Answer: Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell. Indeed, apart from random mutations, each successive duplicate cell will have the same genetic composition as its parent, due to the inheritance of the same chromosome set and similar biological environment. This works well for replacing damaged tissue or for growth and expansion from an embryonic state.

Because the genes contained in the duplicate chromosomes are transferred to each successive cellular generation, all mitotic progeny are genetically similar. However, there are exceptions. For example, there are genetic variations that arise in clonal species, such as bacteria, due to spontaneous mutations during mitotic division. Furthermore, chromosomes are sometimes replicated multiple times without any accompanying cell division. This occurs in the cells of Drosophila larvae salivary glands, for example, where there is a high metabolic demand. The chromosomes there are called polytene chromosomes, and they are extremely large compared to chromosomes in other Drosophila cells. These chromosomes replicate by undergoing the initial phases of mitosis without any cytokinesis (Figure 2). Therefore, the same cell contains thick arrangements of duplicate chromosomes side by side, which look like strands of very thick rope. Scientists believe that these chromosomes are hyper-replicated to allow for the rapid and copious production of certain proteins that help larval growth and metamorphosis (Gilbert, 2008).

Gene Transmission in Meiosis

Three photomicrographs show polytene chromosomes. The chromosomes look like horizontal tubes composed of white, grey, and black bands against a black background. They look like thick, striated lengths of rope.

Figure 2: Examples of polytene chromosomes

Pairing of homologous chromatids results in hundreds to thousands of individual chromatid copies aligned tightly in parallel to produce giant, "polytene" chromosomes.

Although he did not know it, Walther Flemming actually observed spermatozoa undergoing meiosis in 1882, but he mistook this process for mitosis. Nonetheless, Flemming did notice that, unlike during regular cell division, chromosomes occurred in pairs during spermatozoan development. This observation, followed in 1902 by Sutton's meticulous measurement of chromosomes in grasshopper sperm cell development, provided definitive clues that cell division in gametes was not just regular mitosis. Sutton demonstrated that the number of chromosomes was reduced in spermatozoan cell division, a process referred to as reductive division. As a result of this process, each gamete that Sutton observed had one-half the genetic information of the original cell. A few years later, researchers J. B. Farmer and J. E. S. Moore reported that this process—otherwise known as meiosis—is the fundamental means by which animals and plants produce gametes (Farmer & Moore, 1905).

The greatest impact of Sutton's work has far more to do with providing evidence for Mendel's principle of independent assortment than anything else. Specifically, Sutton saw that the position of each chromosome at the midline during metaphase was random, and that there was never a consistent maternal or paternal side of the cell division. Therefore, each chromosome was independent of the other. Thus, when the parent cell separated into gametes, the set of chromosomes in each daughter cell could contain a mixture of the parental traits, but not necessarily the same mixture as in other daughter cells.

To illustrate this concept, consider the variety derived from just three hypothetical chromosome pairs, as shown in the following example (Hirsch, 1963). Each pair consists of two homologues: one maternal and one paternal. Here, capital letters represent the maternal chromosome, and lowercase letters represent the paternal chromosome:

Pair 1: A and a

Pair 2: B and b

Pair 3: C and c

When these chromosome pairs are reshuffled through independent assortment, they can produce eight possible combinations in the resulting gametes:

A B C

A B c

A b c

A b C

a B C

a B c

a b C

a b c

Hey there,

When making a heading for your essay, it should be located in the beginning of the whole essay. This is what makes the essay come to life and what start's off the essay well.
