Question

in what way do adaptations help the survival of a species?
a. they increase the genetic diversity of the species.
b. they prevent reproduction from happening.
c. they ensure that many alleles are passed on.
d. they reduce the number of alleles.

Explanation:

Adaptations are traits that enhance an organism's ability to survive and reproduce in its environment. When different adaptations exist within a species, it leads to a greater variety of genetic material (genetic diversity). This diversity is crucial because it provides a "pool" of traits that can help the species respond to environmental changes (such as new predators, diseases, or climate shifts). For example, if a disease emerges, some individuals with certain adaptations (due to their genetic makeup) may be resistant and survive, allowing the species to continue. Options B (preventing reproduction would harm the species' survival), C (while passing on alleles is part of it, the key is the diversity that adaptations bring), and D (reducing alleles would decrease genetic diversity and harm survival) are incorrect.

Answer:

A. They increase the genetic diversity of the species.
