How are learned behaviors related to natural selection?
a. learned behaviors do not directly affect natural selection because they do not improve the chances that an individual will survive and reproduce.
b. as organisms learn to survive in their environment, their genes change. they then pass these genes to their offspring, and the traits become more common within a population.
c. as organisms learn to survive in their environment, they teach these skills to their offspring. in this way, these traits become more common within a population.
d. learned behaviors do not directly affect natural selection because they are not inherited.

What food can provide the body with a quick source of the energy needed to carry out cell functions (a) whole grain bread (b) ground hamburger (c) vegetable oil (d) whole milk

The dna in a cell’s nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell. for example, consider these two proteins: phosphofructokinase (pfk) is an enzyme that functions in the cytoplasm during glycolysis. insulin, a protein that regulates blood sugar levels, is secreted from specialized pancreatic cells. assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations.for each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)

Which statements describe resources? one of the factors people use when deciding where they will live is the availability of resources. renewable resources have little value for people. resources are unevenly distributed throughout the world. energy is the world resource which has the highest use. the use of nonrenewable resources has decreased in recent history. the use of resources is evenly distributed throughout the world. the world's oil supply will last for the next forty years if its use continues as expected.
