Answer:
Almost all the animals can heal wounds, but only some can regenerate. One hypothesis is that certain regeneration-specific genes are expressed exclusively in regenerative species and evolutionarily lost in nonregenerative species.
Explanation:
Good luck and have a great day!

Anorexia is a mental disease that causes the patient to experience fear of gaining weight. In this case, the patient will try to limit their food intake(in an extreme way) or induce vomit to remove the food.
The effect should be same as starvation or malnutrition. As the food intake decreased, blood glucose is decreased too. The body adapts by lowering the basal metabolic rate so it loses less energy. Insulin and leptin will be decreased too as it was not needed.
Answer:
d. The species diversity of plot 2 is greater than that of plot 1.
Explanation:
Species diversity of an area depends on its species richness and species evenness. Species richness is the number of species present in that area. Species evenness measures how evenly these species are distributed.
Here, both plot 1 and plot 2 have same number of species. They both have four species of trees ( maple, birch, oak and pine) hence their species richness is same. However plot 1 has 85% maple trees and the rest three species make the remaining 15%. Plot 2 has more even distribution as 35% of trees are maple trees and birch and oak also have similar frequency with 25% and 35% respectively. Hence, plot 2 has more evenness.
Species diversity depends on both richness and evenness. Since plot 1 and 2 have same richness but plot 2 has more evenness, plot 2 has more species diversity than plot 1.
