A. They develop from the same embryonic
tissue.
Human
Bird
B. They are the most important sets of
bones.
C. They have no current use.
D. These animals do not share a common
ancestor.
Answer: its A
Explanation:
They have no current use, because they were passed down from a common ancestor, homologous structures are those that are comparable in related organisms, hence option C is correct.
What is homologous structures?The descendants of these structures may or may not carry out the same purpose. Tetrapods' four limbs are an illustration of homologous features. All four limbs are present in birds, bats, mice, and crocodiles.
Bony fish such as sharks do not. Tetrapods evolved four limbs, and their descendants have carried on this trait.
As a result, the presence of four limbs is a homology. The upper arm of both humans and cats consists of just one bone, which we refer to as the humerus, and two forearm bones, the radius on the more medial side and the ulna on the more lateral side.
Therefore, option C is correct.

The number of chromosomes is DOUBLED after mitosis. True or False, AND explain.
PLEASE HELP IT'S DUE TODAY!!!!
Answer:
False
Explanation:
The number of chromosomes is doubled during mitosis, but each daughter cell (new cell) has the same number as the mother (original cell)
Mitosis is a cell division cycle in which the parent cell divides to produce equivalent daughter cells. It can occur in the body for growth, replacing dead cells etc.
The statement is False.
The sentence can be explained as:
Mitosis is a function of division in cells in which the two exact daughter cells are produced from the parent cell division of the nucleus and cytoplasm.The parent cells undergo the doubling of the hereditary content by the process of central dogma during the synthesis stage. The parent and daughter cell is diploid during this sort of cycle and does not get halved or duplicated at the end of the cycle.Therefore, chromosomes do not get doubled at the end of the division.
