Angiogenesis is the new blood vessels formation. After strenuous exercise, local [X] would be least similar to post-exercise [Z] in subjects in group A.
<h3>What is the impact of exercise?</h3>
After any exercise, a person's body repairs or replaces muscle fibers damaged during the exercise by fusing muscle fibers together to form new muscle protein strands called myofibrils. 
These replaced myofibrils increase in thickness and number to form muscle hypertrophy. These larger muscles require more blood vessels. 
If cytokine X acts to promote angiogenesis in the new muscle tissue, it will mean a person would expect large increases in the local concentration of X. 
Thus the group that is least similar to this large increase in local [X] would be the group with the less increase in [Z] which is group A.
Thus, the correct option is for subjects in group A.

Krill in this food web is the primary consumer. Since the producer of the food web is the phytoplankton. Removing them from the food chain cuts the supply of food for secondary consumers such as seals, and whales. This disrupts the whole Antartic ecosystem since there will be a large amount of phytoplankton but not enough food for secondary consumers. This because secondary consumers are not able to eat phytoplankton due to their microscopic size. Only krill are able to feed on them and have the maximum energy gain from them.

Background extinction refers to the normal extinction rate. These are species that go extinct simply because not all life can be sustained on Earth and some species simply cannot survive. Mass extinction is a widespread event that wipes out the majority (over 50%) of living plants and animals.
