We can expect that the life table of these Minnesota bluegills will indicate high early mortality in a Type III survivorship curve.
The central nervous system has two functions. One, where the brain is, is to be the center of thoughts and the interpreter of outside influences, while the spinal cord connects all parts of the body with the brain.
This is a typical example of R selection life strategy. These species, including the Atlantic cod, produce a large number of offspring with a low chance of surviving to adulthood. This strategy is particularly successful in environments that are unstable. The main advantage of this strategy in changing environments is that the ''cost'' of making offspring is very low, so you the species can produce large numbers offspring, ensuring that at least some of them will survive into adulthood and continue the species.
Natural selection, in this case, favors the individuals that are able to adapt the fastest to the changing conditions.
Skin cells are also called epithelial cells
