a. bats are more closely related to honeybees than to humans.
b. since they are the result of evolution, honeybee wings and bat wings are homologous structures
c. since they do not come from a common ancestor, honeybee wings and bat wings are analogous structures.
d. since they both have wings and humans do not, neither bats nor honeybees are related to humans at all.

the correct answer is

C) Since they do not come from a common ancestor, honeybee wings and bat wings are analogous structures.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
