What term describes the amount of energy a body needs at rest for basic functions?

Basal/resting metabolism is described as the basic energy that should be present while rest so the proper functioning of body can be maintained.

Explanation: Basal metabolism is the rate of calories that should be present  while the particular person is at rest so that afterwards the functioning of body parts can be normal. This is the important factor for the body to maintain its supportive nature. If the metabolism in the body increases , then there is the increase in the basal metabolism rate as well.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
