The correct answer is A. Scientists reintroducing crested toads into the wild.
Explanation
Species Survival Plan is a conservation program promoted by conservationists and zoologists that specializes in those animals that are near extinct, endangered, or threatened. This program mainly aims to breed these species in captivity to ensure their future preservation and reintroduction to nature. According to the above, the effect that could be expected from the implementation of the Species Survival Plan in Puerto Rico with the crested toads would be the reintroduction of this species into the wild after being bred in captivity.

Chromosomes are rod shaped structures that contain DNA, are located in the nucleus, occur in numbers that are the same for all members of a certain species, are organized into karyotypes for scientists to analyze
<h3><u>
Explanation:</u></h3>
A chromosome is the threadlike arrangement of DNA and protein-containing genetic erudition. Chromosomes are packaged and saved inside the nucleus. Various species have distinct amounts of chromosomes. An organism's complete assortment of chromosomes can be observed by practicing pictures of cells dividing. These pictures are then designed to produce a karyotype. 
All the various chromosomes of an organism get up that organism's genome.DNA is the construction block of the genetic material observed in all living things. A very long chain of DNA can create a chromosome. In these chromosomes are areas designated as genes that code for particular proteins.
