Answer:
Answer is C. Structures of animals that have different appearances and functions but seem to have evolved from the same body part in a common ancestor.
Explanation:
This can be found in Cat's leg and human arms.the structure do not need to look the same or perform the same functions.
Since circumcision is still a surgical procedure, the medical priority in this case is getting consent to do the surgical procedure. Since the baby is a minor, either parent of the baby can sign the informed consent saying that they have consented to the operation.
MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.
The cell cycle ensures the duplication of the genome and its distribution in daughter cells by passing through a coordinated and regulated sequence of events.
A series of checkpoints guarantee the orderly progression of the phases of cell division and the correct distribution of the duplicated genetic material in the daughter cells.
The checkpoints during mitosis are:
- At the end of stage G1 and before S.
- Before anaphase in mitosis.
- DNA damage checkpoints in G1, S or G2.
The checkpoint before anaphase in mitosis guarantees the separation of chromosomes, and operates by activating the Mad2 protein that prevents the degradation of segurin, until the conditions are appropriate.
That is, the Mad2 protein prevents the segregation of sister chromatids until they have all bound to the spindle.
Therefore, we can conclude that MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.

Answer:
Exercise is important for the body to function properly.
Explanation:
Exercise helps a person to maintain the oxygen amounts in the body. Exercise, as such, enhances and regulates almost every system of the body including the nervous, respiratory, circulatory and hormonal systems.
The sympathetic division of the autonomic nervous system controls the physical activities in a person's body by detecting the low levels of oxygen and increasing amounts of carbon dioxide in the body.
Different systems<span> of the body have different functions. For example, your </span>digestive system<span> is responsible for taking in & processing food, while your </span>respiratory system—working<span> with your</span>circulatory system<span>—is responsible for taking up oxygen and getting rid of carbon dioxide. Hope this helps</span>
