2. which of the following do all animals not need to do in order to a. capture prey.
b. obtain oxygen.
c. eliminate waste.
d. avoid predators.

3. how would having a prehensile tail a tree-dwelling chameleon? a. its tail would it grasp branches.
b. its tail would it capture food.
c. its tail would it balance in the treetops.
d. its tail would it maintain homeostasis.

2. A. capture prey, and D. avoid predators

3. A. Its tail would help it grasp branches.

Explanation:

All animals need at least food, oxygen, shelter, space to survive. These needs, which are common to all animals, are fundamental to their survival and successful reproduction. However, from the options given in the question, not all animals need to capture prey to survive, as not all animals are carnivores. Some are herbivores that feed on plants, and do not prey on other animals. Also, not all animals need to avoid predators. For example, lions are predators and carnivores, they do not need to avoid predators. The correct options are option A and option D.

A prehensile tail is a tail that is adapted for grasping or holding, and it is common among arboreal animals, i.e. animals that dwell on trees. Therefore, a prehensile tail would help a tree-dwelling chameleon to grasp branches. The correct option is "A. Its tail would help it grasp branches."

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
