7 0

The answer is A. True.

Plankton includes a diverse group of organisms that live in the water but are not capable of active swimming against the water current. On the contrary, nekton includes a diverse group of organisms that live in the water but are capable of active swimming without the help of the water current. A shark is capable of active swimming, therefore, it is the example of nekton.

Answer:

c. Beginning with the return from the systemic circulation, blood enters the right atrium. 

a. Blood enters the right ventricle from the right atrium through the right atrioventricular valve which is also known as the tricuspid valve

d. The right ventricle contracts next, which forces blood up through the right semilunar valve which is otherwise known as the pulmonary valve .

e. After circulating through the pulmonary capillaries, the blood returns to the left atrium. 

f. From the left atrium, blood moves through the left atrioventricular valve which is also referred to as the bicuspid or mitral valve.

b. From the left ventricle, the blood is pumped up to aorta the through the left semilunar valve which is sometimes referred to as the aortic valve.

Answer:

Analogous structures

Explanation:

Analogous structures are similar structures that evolved independently in two living organisms to serve the same purpose.

Analogous structures are examples of convergent evolution, where two organisms separately have to solve the same evolutionary problem – such as staying hidden, flying, swimming, or conserving water – in similar ways. The result is similar body structures that developed independently.

In the case of analogous structures, the structures are not the same, and were not inherited from the same ancestor. But they look similar and serve a similar purpose.

For example, the wings of an insect, bird, and bat would all be analogous structures: they all evolved to allow flight, but they did not evolve at the same time, since insects, birds, and mammals all evolved the ability to fly at different times.

A feeding adaptation an iguana has is it’s short nose. This feature is important for feeding because it helps it eat algae off rocks.

Marine and Land iguanas have similar traits even though they aren’t the same kind of iguana because, most of their predators are the same. Therefore a bird or other prey would not be able to tell the difference so that’s why land and marine would both need spines on their back.

I think the camouflage is the most beneficial in land iguanas because their predators can’t spot them that easily, and it’s a quick way to blend in. I also think that the iguanas nose on marine iguanas is the most important because when they eat algae it’s easy to eat and they don’t have to change their position when feeding.
