One method to reduce the risk of extinction is to create gene banks. What are gene banks? (A) A payment that is made toward the conservation of a species. (B) A secure place where the genetic material of a species is stored. (C) Small sections of DNA that are stored and can be genetically engineered into different species. Or (D) a store of genetic material within an organism that can be extracted to produce new individuals.

You may remember, as this question indicates, that gene banks can be used in the effort to avoid the extinction of a species. Extinction refers to the end of the existence of a species, because all of the living members of that species have died, leaving no offspring.

We can’t avoid the fact that the living members of any species will die at some point. So, the purpose of using a gene bank is to address the issue of offspring. If scientists can use methods to produce more offspring of a species, they may be able to increase the number of living individuals and ultimately help prevent the extinction of that species.

How do gene banks help produce more offspring? Well, gene banks store reproductive material. For endangered plants, this might include storing seeds or cuttings of the plants, which can be used to produce more plants of that species. For animals, gene banks may store sperm and egg that can likewise used to produce offspring through assisted reproduction. So, gene banks are where reproductive material such as seeds, cuttings, sperm, and egg are stored. And they are particularly used to store the reproductive material of species in danger of extinction, to be used to try to help prevent that extinction.

Therefore, the correct answer to this question is (B). A gene bank is a secure place where the genetic material of a species is stored.
