Which explanation identifies correctly how the G protein-linked receptors are similar? O Insulin is an example of the second messenger cyclic AMP (CAMP), which binds to an enzyme-linked receptor.
O Their cytosolic domain has intrinsic enzyme activity.
They have a ligand-binding extracellular receptor component, which causes changes that activate the protein on the cytoplasmic
side of the cell membrane.
These linked receptors are involved in rapid synaptic signaling between cardiac electrical cells.

Some species of wasps are social. the queen starts a colony from scratch each spring. she builds a small nest, and lays and raises a group of female workers. the workers enlarge the nest while the queen continues to lay eggs. unfertilized eggs become males that mate with newly hatched females. all of the wasps except the newly fertilized females die by the summer. which best describes this behavior? a)it is beneficial only to the males that do not fertilize eggs. b)it is beneficial only to the female workers that are not fertilized. c)it is beneficial to each one of the individual colony members. d)it is beneficial to the whole species, but not to all of the individual members.
