External respiration (correct answer) involves the exchange of oxygen and carbon dioxide within the environment.
The exchange of wastes through the skin is just called excretion by sweating.
There is no exchange of nutrients that occur in the lungs but rather absorption of nutrients is the function of the gastrointestinal tract.
The exchange of oxygen and carbon dioxide within the cell is called cellular respiration and involves carrying oxygen from the blood to the cell then the cell uses it as the final electron acceptor in the electron transport chain. The metabolic wastes of the cell, primarily carbon dioxide, goes now to the bloodstream to be exchanged for oxygen in the lungs.
Answer:
for food, water, shelter, mates, light, and other resources needed for survival and reproduction.

Peacocks would not be in Hardy-Weinberg Equilibrium
Explanation:
This can be justified by the mating patterns of the female peacocks. They do not choose their mates randomly but look out specifically for bright attractive plumage in their male partners and then select them.
Hardy-Weinberg's Equilibrium of evolution mechanism was based on facts like random mating, no natural selection, mutation, absence of gene flow, and infinite population size.
They stated that organisms mate randomly with each other without any specific or a particular preference in the phenotypes of their opposite mates
Keystone predators can maintain species diversity in a community if they prey on the community's dominant species
Option B is correct.
What is meant by keystone predator?
A keystone species is usually a dominant predator whose removal allows a prey population to explode and often decreases overall diversity. other forms of keystone species are those, like coral or beavers, that significantly alter the habitat around them and thus affect large numbers of other organisms.
Are keystone species always predators?
A keystone species is usually , but not always, a predator. Just some predators can control the distribution and population of large numbers of prey species. the whole concept of keystone species was founded on research surrounding the influence of a marine predator on its environment.
