A shared derived trait is a unique feature common to all members of a group that originated in the group's most recent common ancestor (Option B). It is evolution.
What is a shared derived trait?A shared derived trait is an evolutionary phenotypic feature present in the common ancestor of a taxonomic group.
This trait (shared derived trait) can then be used to trace the evolutionary relationships in a taxon.
A shared derived trait can be a homo-logous structure that suffered divergence across time.

5. a) The human body produces hundreds of different enzymes. Why can't one type of enzyme be used
everywhere in the body? (4 points)
b) Pepsin is an enzyme in the stomach that helps break down proteins. What problems would you expect a
person to have if his or her stomach did not have enough pepsin? (2 point)
Answers
a) A single type of enzyme could not be used in every region of the body because the body is not a single celled organism, it is a multicellular organism and each cell needs special and specific care in order to function.
A single type of enzyme could not control all the different systems of the body. Different enzymes and specialized cells have the responsibility to carry out specific functions so that the body can properly operate. One type of enzyme could not manage the excretory, digestive, reproductive, skeletal systems etc as these regions of the body require distinct attention and assistance to keep the body regulations active and to maintain proper health.
b) Problems expected of someone who lacks pepsin would be a protein deficiency. This would be present by way of weak and brittle bones and overall immuno compromised health.
Another problem expected would be stunted growth and development. As an individual is not receiving the right and recommended amount of digested protein, their bodies will lack the nutrients to properly grow as they age.

Hope it helps!!! brainliest pls!!!Remember, prophase, metaphase, anaphase, and telophase represent the stages of Mitosis - not
Interphase. Which stage of mitosis takes the least amount of time?
Answers
Answer:
Why is anaphase the shortest stage? The kinetochore microtubules shorten as the chromatids are pulled toward opposite poles, while the polar microtubules subsequently elongate to assist in the separation. Anaphase typically is a rapid process that lasts only a few minutes, making it the shortest stage in mitosis.
