Question

genetic bottlenecks can be caused by __. flood. extreme temperatures. hunting. overfishing. all of the above. question 10 true/false. populations evolve and individuals adapt. true false

Explanation:

• Question 9: A genetic bottleneck occurs when a population's size is drastically reduced. Natural disasters like floods (A) and extreme temperatures (B), as well as human - caused activities such as hunting (C) and overfishing (D) can all cause a significant reduction in population size, leading to a genetic bottleneck. So all of these factors can cause genetic bottlenecks.
• Question 10: Evolution is a change in the genetic composition of a population over time. Adaptation is a process by which an individual becomes better suited to its environment. Populations evolve as the frequencies of genes change within the group. Individuals can adapt through physiological or behavioral changes during their lifetime. So the statement “Populations evolve and individuals adapt” is correct.

Answer:

• Question 9: E. All of the above
• Question 10: A. True
