After many hours of observation, Jennifer notice that a squirrel in her backyard retreated up a certain tree every time it was frightened. At the base of the tree was a wheelbarrow. Jennifer wondered how the squirrel found the same tree every time. That night, she moved the wheelbarrow to the base of another tree. The next day, the squirrel retreated up the new tree. This experiment suggest that the squirrel was using

Which of the following statements regarding genotypes and phenotypes is false?
Genotype is the genetic makeup of a trait and phenotype is the appearance or expression of that trait
Which of the following statements regarding sickle cell disease is false?

25% or none of the sons
A big difference between social learning and imprinting is that
imprinting is learning that is irreversible and limited to a sensitive time period while social learning is learned by observing and mimicking others.
Which of the following is most clearly a case of density dependent population regulation?
A population- limiting factor whose intensity is linked to population density. For example, there may be a decline in birth rates or a raise in death rates in response to an increase in the number of individuals living in a designated area.
A group of individuals of a single species that occupy the same general area defines a?
populations
