The answer is; A gopher snake occupies a burrow made by the desert rat
Commensalism involves a relationship between two organisms where one benefits while the other is unaffected. In this case, the gopher snake gets from the burrow made by the desert sake. The desert rat is unaffected (does not benefit or lose) by this action by the snake.
1. The population is under selection pressure from predators
<span>2. Hey now, no population is ever at H-W equilibrium: </span>
<span>mutations happen </span>
<span>immigration and emigration can occur </span>
<span>the population is not huge, which means that genetic drift can happen </span>
<span>mating is not completely random -- a rat is more likely to mate with someone local than with someone living in Paris, France. </span>
<span>b) The small rats will be selected for (assuming there are predators in this ecosystem that are less likely to look in bushes, and further assuming that the small rats do not have reduced fertility by dint of being small) </span>
<span>This is "directional selection" </span>
<span>c) I would expect the "smallness" allele frequency to increase in this population over time, and the "normal size" allele frequency to decrease.</span>

Answer:
Fragile X syndrome is a genetic condition that causes a range of developmental problems including learning disabilities and cognitive impairment. Usually, males are more severely affected by this disorder than females. Affected individuals usually have delayed development of speech and language by age 2.
During the cell cycle, it skips the whole process in the cell cycle to produce a cell, which causes errors within the cells and produce more of these errors. This how cancer occurs.
