Out of the following given choices;

a. they increase the amount of energy transferred from the lungs to the blood

b. they increase the flexibility of the lungs as they expand during inhalation

c. they increase the volume of the lungs, allowing more oxygen to be inhaled

d. they increase the surface area of the lungs, allowing the efficient gas exchange

The answer is D. Due to their microscopic nature, they are numerous in the lungs and are also circular-shaped so as to increase the surface area for gaseous exchange. Other characteristics of alveoli that increase gas exchange are that they thinned-walled (with only a layer of cells) and moist.

Which graph most likely represents a rabbit population that found a new, larger habitat, but then eventually experienced an
klio [65]

The graph will have a sharp curve in upwards manner when the new, larger habitat is found, but than will be followed by slight decrease when the predation increases.

Explanation:

If a population of rabbits finds a new, larger habitat, than the population will experience rapid rise, especially if there isn't high scale predation on them. This will be due to the abundant food resources, but also because of the fast reproduction of the rabbits. The low predation will mean that most of the rabbits will survive, so the numbers will be on the rise.

When the population starts to experience in increase in predation, the situation changes. The larger number of predators means that they would need much more food, so much more rabbits will be killed and consumed by the predators. This will stop the population rise, and it will either stagnate, or most probably it will experience slight decline.
