Identify each adaptation as structural or behavioral adaptations.
Zina [86]

Answer:

Monkeys have a prehensile tail that allows them to grab and hold onto tree branches - structural

Moose make mating calls to locate potential mates - behavioral

Whales are covered in a thick layer of blubber, insulating their bodies in cold ocean waters - structural

Humans have five toes on each foot to help them maintain balance - structural

Many birds migrate south for the winter in search of food - behavioral

Explanation:

The structural adaptations are adaptations that help the organisms to survive in their environment through development of physical traits that give them an advantage. Such adaptations are the thick layer of blubber of the whales, the five toes of the humans, prehensile tail of the monkeys, rotational toe of the clouded leopard, long of the giraffe etc. The behavioral adaptations are adaptations that help the organisms to survive in their environment, but they manifested through their actions, not their physical traits. Such adaptations are the mating calls of the moos, the migration of the birds in winter, the hibernation of the bears etc.

Answer:

The correct answer is B. water will leave the balloon.

Explanation:

As the sucrose concentration is higher in the solution, the water in the balloon, where the sucrose is less concentrated, will tend to leave and try to dilute the outer solution until both sucrose concentrations are equal. But as the water leaves the balloon, the concentration inside will increase, so it will flow outside until both concentrations are equal and not until the outer concentration is similar to the initial concentration in the balloon.
