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?
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 ValveThe 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.

You close your eyes, with your hand in front of your face for one minute. You quickly blink your eyes and find that even with your eyes closed, you can "see" your hand briefly. Why does this occur?
1) because elaborative rehearsal has transferred this image to your Long-Term Store/Memory, where it is stored indefinitely
2) because auditory images are held in Sensory Store/Memory for up to several seconds
3) because visual images are held in Sensory Store/Memory for up to about 1/4 second
4) because maintenance rehearsal keeps this image in your Short-Term Store/Memory indefinitely
Answer:
because visual images are held in sensory store/memory for up to 1/4 second
You can "see" your hand briefly because visual images are held in Sensory
Store/Memory for up to about 1/4 second.
When the sensory organ involving the eyes views an object briefly, the
information is usually passed to the brain which tells the type of object and
the action to take in response to the stimuli.
In this case, the visual image are usually held in the sensory
store/memory(brain) for few seconds which is why it is seen briefly even
after closing the eyes.

What does the graph tell you about the concentration of salt inside the cell?
Answer:
So,
Assuming that the plasma membrane is either semipermeable or fully permeable, either diffusion or osmosis will even out the concentration eventually. Therefore, options A and B are eliminated.
The only options left both say that osmosis will take place. We know that osmosis will always move the solvent from an area of low solute concentration (outside the cell) to an area of high solute concentration (inside the cell). Thus, water will move into the cell through osmosis. That is option C.
If the cell cannot get rid of the water quickly enough, the cell will explode by cytolysis.

describe evidence from biogeography that species evolve adaptations to their environment
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.

Fill in the blank with the correct term to complete the sentence provided. When the valve between the right atrium and right ventricle has an abnormal narrowing, this is known as
(Answer is NOT pulmonary valve or pulmonary stenosis)
Explanation:
if its correct please let me know
A narrowing of the valve between the lung arteries and the lower right heart chamber (right ventricle) is known as pulmonary valve stenosis (pulmonary arteries).
What is an abnormal narrowing in the heart?The valve flaps (cusps) of a constricted heart valve may thicken or stiffen, as a result, the valve's blood flow is decreased.
When that valve narrows, blood cannot flow correctly and aortic stenosis develops, mild to severe cases of the illness are possible.
The left ventricle of your heart has to work harder over time to force blood past the stenotic aortic valve.
Therefore, an abnormal narrowing of the right atrium and right ventricle is due to pulmonary valve stenosis.
