Studies of the similarity of the DNA in wasps and bees suggest that the first bees appeared about 130 million years ago, 50 million years before the first known fossil bee, and probably very shortly after the first flowers evolved in the Cretaceous.
<span>Since we are not able to get energy directly from the food we eat, a particular process needs to take place that converts molecules to Adenosine triphosphate, also known as ATP. This requires that the food first be broken down by being digested. As digestion takes place, the body uses the small molecules to make ATP.</span>
I think it’s A or c but I’m not so sure
Effector, control center, receptor, and feedback are all involved in maintaining homeostasis. Lack of change is NOT involved in maintaining homeostasis.<span />
I think it’s C I hope it’s right I’m sorry if I’m wrong
