Pandas have what appears to be a sixth digit on each of their forepaws. Some refer to this as the panda's "thumb." Actually, this thumb is really just a modified wrist bone (sesamoid bone)
Pandas use their thumb much like humans use their thumbâ€"to better hold objects.
For the panda, they hold onto stalks of bamboo and are able to strip the leaves off the stalk
so that they may eat the leaves.
t or f: The pandas "thumb" is the result of natural selection.
t or f: It was in the pandas best interest to choose this adaptation so they could forage more
efficiently and increase their fitness.
t or f: It was in the male pandas best interest to choose this adaptation so they could forage
more efficiently and increase their fitness.

A bird sanctuary sometimes takes over the care of eggs or chicks of an endangered duck species if the parents are killed. They are sometimes able to use mothers of farm ducks to cross-foster the chicks, but it doesn't always work. Looking at the following data table, what is the critical period for imprinting in this species? (Note: DAH stands for "days after hatching".)
A. The critical period extends from 1-3 DAH.
B. The critical period extends from 3-8 DAH.
C. The critical period ends sometime between 1-3 DAH. We can not determine from this data when the critical period begins.
D. The critical period ends sometime between 3-8 DAH. We can not determine from this data when the critical period begins.

Salmon eggs hatch in freshwater. The fish then migrate to the ocean (a hypertonic solution) and, after several years of feeding and growing, return to freshwater to breed
How can these organisms make the transition from freshwater to ocean water and back to freshwater? A) The rectal gland functions in the ocean water, and chloride cells function in freshwater. B) Different gill cells are involved in osmoregulation in freshwater than in salt water. C) Salmon in freshwater excrete dilute urine, and salmon in salt water secrete concentrated urine. D) Their metabolism changes in salt water to degrade electrolytes.
