Answer:
Increase the genetic diversity by introducing other subspecies of cougar to the population.
Explanation:
- Genetic diversity is the total number of genetic makeup of species. It includes the number of species that have differences within the species and is distinguished from the genetic variability.
- The genetic diversity services allow for the population to adapt to the environment and continue to generate more. Thus introducing the subspecies of cougar can be done to save the species from getting extinct.
This is called a chemical bond.
Answer:
b. They are produced by memory B cells
Explanation:
The rapid cell division in activated B cells is followed by the differentiation of daughter cells into the plasma cells. The plasma cells are the precursor for antibodies and memory B cells. The antibodies kill the antigens while memory B cells are long-lived cells.
Hence, antibodies are not produced by memory B cells but by plasma cells.
