Biology

Diploid plants have two sets of chromosomes. Polyploid plants have more than two sets of chromosomes, are often larger, and have more desirable characteristics. To create polyploid plants, plant breeders can treat diploid plants with a chemical that prevents the separation of sister chromatids during mitosis. Resulting cells that have any partial chromosome sets, even if in addition to one or more complete chromosome sets, typically do not survive this process. If a diploid plant cell treated with such a chemical goes through a single round of mitosis, what is the MOST LIKELY genetic composition of the resulting cells that survive?

A
These cells will be haploid, each having one complete set of chromosomes.

B
These cells will be triploid, each having three complete sets of chromosomes.

C
These cells will be tetraploid, each having four complete sets of chromosomes.

D
These cells will be octaploid, each having eight complete sets of chromosomes.

Endangered

Explanation:

Endangered species are organisms that are at risk of extinction if deliberate efforts are not made to conserve them due to a rapid decrease in their population.

Hence, if a marine biologist writes an article about saving whales and labels them as endangered species, all efforts should be geared towards saving the animals lest they go extinct and leave a vacuum in the functioning of the ecosystem.  Every species have the critical roles they play in the functioning of the ecosystem and the extinction of any particular species represents a loss that might not be replaceable.
