Answer:

D. ACTIVE TRANSPORT THROUGH A PUMP PROTEIN.

Explanation:

The process is one which is from a low concentration outside to a high concentration inside (against the concentration gradient) and it requires energy.

Amino acids and monosaccharides can be transported into the cell by facilitated diffusion with the help of a transporter protein and through active transport.

For the question, the appropriate answer is active transport via a pump (Secondary active transport)

An example is the sodium cotransport.

In this process, sodium is transported alongside another substance like amino acids. The energy needed for the movement of sodium is obtained from ATP while the energy released by the movement of sodium is used for the transport of amino acids and glucose.

Develop a hypothesis to explain why you think eurypterids developed legs even though they lived on the ocean floor.
expeople1 [14]

I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor. Their movements mostly on the ocean floor. So fin would not help them "stick" to the floor. Also there are still gravity acts on the Eurypterids and the feet would help them move faster. Hope this helps.

A child falls and suffers a deep cut on her leg. The cut went through her skin and she is bleeding. Which of the following defen
Vesnalui [34]

Answer:

The correct answer is option C) phagocytosis in the inflammatory response.

Explanation:

Our body has an immune response mechanism for when we get hurt or when<u> it feels that something outside our body wants to harm us</u>, so its automatic reaction is to defend against all those bacteria and viruses that want to attack us.

The system is responsible for <u>identifying the antigens and destroying them.</u> The antigens are all bacteria, harmful viruses and dead substances that are found on the cells. Our system has its own proteins that are HLA antigens. But as these are normal for the body, it does not counterattack them.

There are <u>several defense mechanisms that work as barriers</u> to prohibit the passage of any bacteria that harm us, and one of these mechanisms is inflammation.

In this case, when our body suffers some kind of injury from a bacterium, a cut or a blow, the damaged cells release substances that spill onto the tissue through the blood vessels, causing inflammation.

This allows the foreign substance to be “locked up” and cannot enter the body.

These spilled substances also attract white blood cells, which are called phagocytes which<u> are responsible for eating dead germs and cells</u> through the phagocytosis process.
