A silent mutation occurs when a mutation is not changing any amino acid coded for that codon. so, they are also known as missense mutation.

In general, Nucleotide substitutions may lead to no change in the protein sequence which known as silent mutations. so , we can say that a silent mutation is a mutation that occurs within the DNA sequence, but they do not alter the amino acid sequence. These mutations takes place in an introns, that is spliced before translation.

Hence,  example may include Single nucleotide substitutions they are not involved in changing any of the amino acid sequence so termed as silent  polymorphisms. Mutation in these base pair will also not change the function of the protein.

The process of cell division helps the cell to avoid DNA overload by the following mechanism: Each daughter cell has its own copy of DNA and can coordinate all the activities of a smaller cell.

Thus, the correct option for this question is B.

Cell division may be defined as a process through which a parent cell significantly divides into two daughter cells with an identical amount of genetic material.

DNA overload deals with the mechanism of the larger the cell, the greater the requirement for the positioning of the cell's DNA. In order to prevent this mechanism, a cell undergoes the process of division that limits the phenomena of DNA overloading.

This happens with the help of synthesizing two new daughter cells that limit the size of the parental cell. Therefore, the correct option for this question is B.

Whatever happens to a placental after delivery?

The placenta usually breaks from the uterine lining after childbirth. The placenta may still be partially or entirely attached to the uterus when there is placental accreta. This condition happens when the blood vessels and other parts of the placenta encroach too deeply into the uterine lining.

What benefits may you expect if you eat your placenta?

Despite suggestions that eating the placenta can reduce postpartum hemorrhage, increase mood and energy, increase milk production, and provide essential micronutrients like iron, there is no evidence to support any health benefits. You can suffer from placentophagy.

If an organism has a diploid number of 50, and one of its cells undergoes meiosis, then the number of daughter cells produced by this cell is four and each contains 25 chromosomes.

Diploid may be defined as a condition that determines the existence of two complete sets of chromosomes in an organism's cells, with each parent contributing a chromosome to each pair.

On contrary, haploid cells generally contain only a single set of chromosomes. These types of cells are formed due to the process of meiosis, while diploid cells are formed by the activity of mitosis.

According to the question, if a diploid number of an organism = 50.

This means that 2n = 50,

n = 25.

As we all know that when a cell undergoes meiosis, it will definitely have half the amount of genetic content in its daughter cells.

Mucosa secretes hydrochloric acid which chemically digests food. Once food is mixed with this secretion it is called chyme.

Chemical digestion is the process of changing the molecules of organic matter present in food from complex forms to simple forms with the help of enzymes.

Mucosa is a tissue that lines all cavities in our body such as the tongue and digestive tract. In the digestive tract there is tissue that lines the surface of the stomach so that the stomach wall is protected from gastric acid abrasion. Mucosa will secrete hydrochloric acid which will activate pepsinogen to become pepsin to digest food chemically, namely to break down proteins into proteoses and peptones.

Chyme is food that has been stirred and mixed with stomach acid sap and has become mush after peristaltic events. Peristalsis occurs when the wall of the stomach consisting of three layers of muscles contracts and causes a movement that stirs and mixes food with gastric juice.

A clump of cells in someone's intestine is genetically different from cells elsewhere in his body. These intestine cells have a somatic mutation.

Any mutation that occurs in a cell other than a gamete, germ cell, or gametocyte is called a somatic mutation. This includes any change in the DNA sequence of a somatic cell of a multicellular organism with dedicated reproductive cells.

Somatic mutations are not typically passed on to offspring in the same way that germline mutations can. Plants, which don't have a distinct germline, and animals that can reproduce asexually via mechanisms like budding, like the cnidarians of the genus Hydra, blur this distinction.

Even though somatic mutations are not passed on to the next generation, they can be found in any cell that divides from the original somatic cell. Accumulated somatic mutations are the root cause of many forms of cancer.

The cap that is added to the RNA during processing is an important component in the protein synthesis process. During transcription, this cap, known as the 7-methylguanosine cap, is added to the 5' end of the RNA molecule.

The addition of this cap serves several important functions in the messenger RNA's life cycle messenger RNA (mRNA). To begin with, the cap is required for ribosomes to attach to the mRNA. The cap structure acts as a binding site for ribosomes, which are the cellular organelles in charge of reading mRNA and translating it into protein.

The ribosome recognises the cap structure and uses it as a marker to indicate where translation should begin. Second, the cap prevents the mRNA from being rapidly degraded. mRNAs are constantly attacked by enzymes known as ribonucleases (RNases), which are enzymes that degrade RNA. The cap structure protects mRNA from RNases by making it less accessible to enzymes.

Third, the cap helps to prevent the formation of complex three-dimensional structures in mRNA. The cap structure acts as a marker to indicate where translation should begin, preventing the mRNA from forming complex structures that would obstruct translation.
