This chart shows the annual catch statistics for the red grouper for the state of North Carolina during the 1990’s. Red grouper
begin their lives as females, and the largest fish change sexes to become male during mating season. Only large females mate with these males and lay eggs. You are a fisheries biologist for the state of North Carolina. You are charged with protecting the fish population, while also keeping professional fishermen from losing their jobs. Based on the chart above, what would you conclude and what would your solution be?

You are a fisheries biologist for the state of North Carolina. You are charged with protecting the fish population, while also keeping professional fishermen from losing their jobs. Based on the chart above, what would you conclude and what would your solution be?<span><span>A)There is a serious problem with overfishing of red grouper, so there must be a problem with other fish as well. All fishing for any species should be banned.</span><span>B)There is not a very serious problem. The smaller size and population are probably just due to some bad years. Do nothing and monitor the situation.</span><span>C)There is a problem with overfishing. Ban fishing for large fish so their size and population can recover, but allow the fishermen to take smaller fish.</span><span>D)<span>There is a problem with overfishing of red grouper, but the fishermen need to stay in business. Bring in another species of grouper from Australia, so that there are more fish to catch.
a) recovered from pituitary glands removed from human cadavers.
Explanation:
The human growth hormone is responsible for growth along with cellular proliferation and reproduction in humans.
The hormone is secreted by the pituitary gland.
Therefore, before the recombinant DNA techniques were available the hormone was isolated from the pituitary glands fo human cadavers.
However, this method was not continued because the extract hormone became a source of infection for diseases such as the Creutzfeldt-Jakob disease.
Therefore, alternatives were looked for and with the advent, in recombinant DNA techniques, the scientist was able to successfully make the recombinant human growth hormone as well.
The speed of an object is the distance the object travels in one unit of time. To calculate the speed of an object, divide the distance the object travels by the amount of time it takes to travel that distance.
