Question 1:

What is natural selection?

Explanation: Natural selection is the process by which certain traits become more or less common in a population over time. It occurs when individuals with certain advantageous traits have higher reproductive success, leading to the increased frequency of those traits in subsequent generations.

Question 2:

What is adaptation?

Explanation: Adaptation refers to the process by which organisms develop traits that enhance their survival and reproductive success in their specific environment. These traits are favored by natural selection and contribute to the organism's fitness and ability to thrive in its surroundings.

Question 3:

Which of the following is an example of natural selection?

Explanation: The increased frequency of camouflage traits in a population of prey species is an example of natural selection. These traits provide an advantage by helping the prey species blend into their environment, making them less visible to predators and increasing their chances of survival and reproduction.

Question 4:

Which of the following is a key requirement for natural selection to occur?

Explanation: Variation in heritable traits within a population is a key requirement for natural selection to occur. If all individuals in a population have the same traits, there would be no basis for differential reproductive success based on those traits, and natural selection would not operate.

Question 5:

Which of the following statements about natural selection is true?

Explanation: Natural selection can lead to adaptation and evolution. It acts on individuals within a population based on the fitness of their traits, favoring those that contribute to better survival and reproduction. Over time, this can lead to the accumulation of advantageous traits and the emergence of new species.
