Which is an example of an environmental influence that would most likely result in natural selection?
the soil in a field always has lots of nutrients, so corn plants in a population can grow quickly.
a fish is born with a genetic mutation that produces a longer tail, allowing the fish to swim faster than others in the population.
a food resource disappears in a pond, and some frogs in a population can eat the remaining food resource, while others cannot.
the temperature in a lake remains constant, so most of the turtle population survives to adulthood.

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.)

Body systems are not completely independent they integrate and work together describe one example of the integration between body systems
