why does an embryo not grow in size during the cleavage phase, despite the fact hat its cells are rapidly dividing?

Answers

During the cleavage phase, the embryo undergoes rapid cell division, but the size of the embryo does not increase because the cells are becoming smaller with each division. This is because the embryo is dividing into smaller and smaller cells in a process called blastomeres.

The blastomeres are dividing so rapidly that they do not have time to grow in size before dividing again. Therefore, while the embryo is rapidly dividing, it is not growing in size during the cleavage phase.
The embryo does not grow in size during the cleavage phase despite its cells rapidly dividing because cleavage is a process of rapid cell division without significant cell growth. In this phase, the embryo's cells, called blastomeres, are dividing quickly but not increasing in overall size. The purpose of cleavage is to create numerous cells that will eventually differentiate into various cell types, rather than increasing the size of the embryo. This allows the embryo to have a larger number of cells in a compact size, facilitating efficient cell-to-cell communication and differentiation later in development.

in the S phase, the number of chromatids doubles during replication. What are the chromatids bonded by? What does this mean for the number of chromosomes present in the cell?

Answers

In the S phase of the cell cycle, DNA replication occurs and each chromosome is duplicated, resulting in the formation of two identical sister chromatids. The chromatids are bonded by a centromere, which is a specialized region of DNA that holds the chromatids together. This means that after replication, each chromosome consists of two sister chromatids that are held together at the centromere.

Since the number of chromatids doubles during replication, the number of chromosomes present in the cell remains the same. For example, if a cell had 10 chromosomes before S phase, it will still have 10 chromosomes after replication, but now each chromosome will consist of two sister chromatids.

in an endocrine signaling pathway, what is the process called in which the product of the pathway inhibits its production?

Answers

In an endocrine signaling pathway, the process by which the product of the pathway inhibits its production is called "negative feedback." This mechanism helps maintain hormonal balance and homeostasis within the body.

Endocrine signaling involves the secretion of signaling molecules (hormones) by specialized endocrine cells, which are then transported through the bloodstream to act on target cells in distal body regions. The steroid hormone estrogen, which is produced by the ovary and promotes the growth and maintenance of the female reproductive system as well as secondary sex traits, serves as a prime example. Some signaling molecules function locally, in contrast to hormones, to influence the behavior of neighboring cells. The process in which the product of an endocrine signaling pathway inhibits its own production is called negative feedback. This is a mechanism that helps maintain a balance in hormone levels within the body, preventing the overproduction or underproduction of hormones. Negative feedback is a crucial component of many endocrine signaling pathways and helps regulate various physiological processes.

Answers

The correct answer is "Natural selection leads to evolution."

Natural selection is a process by which certain traits become more or less common in a population over time. It occurs because some individuals have advantageous traits that help them survive and reproduce better than others. These advantageous traits are passed down to their offspring, making them more likely to survive and reproduce as well. As a result, over many generations, the frequency of advantageous traits increases in the population, leading to evolution.

Evolution, on the other hand, is the change in the inherited characteristics of a population over time. It can occur through various mechanisms, including natural selection, genetic drift, mutation, and gene flow. However, natural selection is the most widely recognized and studied mechanism of evolution because it can lead to the adaptation of organisms to their environment and the emergence of new species

if one strand is 5'-gcac-3', the complementary strand must be _____

Answers

If one strand is 5'-gcac-3', the complementary strand must be 3'-cgtg-5'.

In DNA, the two strands are complementary, meaning the nucleotide sequence of one strand determines the nucleotide sequence of the other. The complementary base pairing rules state that adenine (A) pairs with thymine (T) and guanine (G) pairs with cytosine (C).

Therefore, given a sequence of one strand, we can easily determine the sequence of the complementary strand by pairing each nucleotide with its complementary base.

In this case, the original strand is 5'-gcac-3', so we know that the complementary strand must start with a 3'-end, and its sequence will be complementary to the original sequence, with G pairing with C and A pairing with T.  Hence,  3'-cgtg-5' is the complementary strand.
