Which of the following is the best description of adaptation?
1. a characteristic that evolves
2. a characteristic that an organism avoid predators
3. a characteristic that an organism find food
4. a characteristic that an organism survive and reproduce

which of the following is not an example of adaptation?
1. the secretions made by a clown fish to protect the organism from sea anemones
2. the white fur of polar bears
3. an individual choosing to put on a coat and stay warm

3. the migration of a large group of animals from a summer breeding ground to a warmer winter ground would be considered which of the following?

1. behavioral adaptation
2. structural adaptation
3. chemical adaptation

Number 1 is 4

Number 2 is 3

Number 3 is 1

Explanation:

QUESTION 1:

Adaptation is a modification or change in an organism's body or behavior that helps it to survive and reproduce in its environment. An organism needs to adjust to their environment to be able to survive the climatic conditions of the ecosystem, predators and other species that compete for the same food and space.

QUESTION 2:

The first example depicts the clown fish possessing structural features that enables it keep away predators (sea anemones), hence, ensuring its survival in the aquatic environment.

The second example shows a bear with a structural feature (white fur) making it able to survive the polar (cold) region.

The third example is not a feature to enable survival, it is just an action to keep warm.

QUESTION 3:

Behavioral adaptation is the process by which an organism or a species changes its pattern of action to better suit its environment. Any behavior or action that helps ensure the survival of an organism can be considered BEHAVIORAL adaptations. They are the things organisms do to survive, which is contrary to structural adaptation, which is the already possessed physical features that makes them better adapted.

In this example, the group of animals take an action by migrating from a cold to warm region in order to survive
