What is the name for the structure that allows one way movement of blood from the atria to the ventricle on the oxygenated side of the heart?​

Answers

The heart is a muscular organ of the body that pumps blood to the organs of the body.  The name for the structure that allows one-way movement of blood from the atria to the ventricle on the oxygenated side of the heart is;

The Mitral Valve

The valves of the heart prevent the backward flow of blood from the heart. There are four types of valves, namely, the tricuspid valve, the mitral valve, the aortic valve, and the pulmonary valve.

The oxygenated part of the heart is the left side. The mitral valve regulates the flow of blood from the left atrium to the left ventricle.

Therefore, the mitral valve allows one-way movement of blood from the atria to the ventricle on the oxygenated side of the heart.

describe evidence from biogeography that species evolve adaptations to their environment

Answers

Answer:

Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.

To give one classic example, the forelimbs of whales, humans, and birds look quite different on the outside. That's because they're adapted to function in different environments. However, if you look at the bone structure of the forelimbs, you'll find that the organization of the bones is remarkably similar across species. It's unlikely that such similar structures would have evolved independently in each species, and more likely that the basic layout of bones was already present in a common ancestor of whales, humans, and birds.

The Human population is currently:
A: increasing at an increasing rate
B:increasing at a steady rate
C: increasing at a slowing rate
D: Decreasing​

Answer:

A is the best answer for now I think. Because the world population grew by 100 million over the past year

Do turtles have exoskeleton?

Answers

Answer:

Mark me brainliest (⌒▽⌒)

Explanation:

The turtle shell isn't like any other protective element of any living animal: it's not an exoskeleton, like some invertebrates have, nor is it made of ossified scales like armadillos, pangolins, or some snake and reptile species. ... The turtle shell is actually a peculiar evolution of a turtle's bone structure

No. Turtles are vertebrate animals with internal skeletons. Even the shell is made of bone covered by a thin layer of tissue and keratin scutes (material similar to your fingernails). The entire skeleton is on the inside. A turtle’s shell is no more an exoskeleton than your own skull is.
