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.

Answer: The water is warmed up by the sun and then it evaporates into the atmosphere. The sunlight warms the water by its heat.
Water is then cooled down and condensation takes place.
The water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
Water and nutrients that are not recycled on earth are stored in the form of reservoirs.
Explanation:
Answer:
1. 20 chromosomes
2. 10 chromosomes
3. 10 chromosomes
Explanation:
1. The process of mitosis results in the two daughter cells from the same parental cell with exactly the same genetic material. Thus the two cells contain the same number of chromosomes as the parent cell. Therefore if a cell with 20 chromosomes undergoes mitosis will result in the 20 chromosomes.
2. During meiosis I two daughter cells are formed with different ploidy levels as the number of the chromosome reduces to half. Therefore the cell with 20 chromosomes results in two cells with 10 chromosomes.
3. During meiosis II, the two daughter cells formed from meiosis I result in the formation of two more daughter cells with an exact number of chromosome number that is 10 chromosomes.
Answer:
The abiotic factors are non-living factors that interfere with the forest ecosystem. Two abiotic factors are the amount of rain and sunlight. The amount of these two abiotics determines how much a tree will grow or how thick and diverse the population of trees in a forest will be.
