The hyperalgesia that is common in phantom limb pain could potentially be blocked if a new drug was developed that could prevent

gregori [183]

Answer: The answer is B- Diffusion of calcium ions through NMDA receptors.

Explanation:

Phantom limb pain (PLP) is a painful sensation experienced after the loss or amputation of a limb. The limb is no longer there but the individual can still feel real and severe pains in the limb. This occurs soon after surgery.

NMDA is a receptor for Glutamate which is an excitatory neurotransmitter. The activation of NMDA receptors are associated with hyperalgesia which is an abnormally heightened sensitivity to pain.

The right ventricle transports oxygenated blood to the lungs true or false

adell [148]

I believe the correct answer is FALSE.

<h2>Explanation:</h2>

The heart is an organ located at the center of the chest in the thoracic cavity and functions to supply blood to and from tissues giving the tissues oxygen and nutrients while taking away carbon dioxide and waste products. It is divided into 4 chambers and 2 chambers are separated by a muscular wall that prevents mixing of the blood.

<h2>Further Explanation:</h2>

Blood enters the heart via the vena cava which is divided into the superior vena cava that recieves blood from the upper region of the body that includes the head, neck and chest while the inferior vena cava recieves blood from the lower extremeties that includes the legs, the abdomen, the pelvic region and the thighs. The blood is deposited into the right atrium and is de-oxygenated. When it is deposited into the right atrium, the change in volume of the atrium and the expansion causes the valve to open and allow the de-oxygenated blood to flow into the right ventricle. The right ventricle then pumps the blood that is de-oxygenated to the lungs via the pulmonary artery which is the only artery that pumps de-oxygenated blood. In the lungs, carbon dioxide is removed and oxygen added to the blood and is taken to the left atrium which pumps the oxygenated blood to the left ventricle and then the left ventricle pumps the oxygenated blood to the rest of the body. The blood is then again taken through the body via the capillaries and the veins pick up the blood that has been removed of oxygen and added with carbon dioxide and transport the blood back to the heart via the vena cava. It enters the right atrium via both the inferior and superior vena cava and the de-oxygenated blood is circulated again to the lungs for oxygenation from the left ventricle.

For each of the following statements, indicate whether the statement describes the P generation, F1 generation, or F2 generation

madreJ [45]

Answer:

The plants that were allowed to self pollinate were the First filial generation, filial, Latin for family. Or just the F1 generation plants.

The plants that are true breeding are Parental generation or for shorthand, the P generation plants.

The plants where there were three times as many tall plants as short plants are in the second filial generation, or the F2 generation.

This question is based on the Mendel’s Experiment.

Sir Gregor Johann Mendel.

mariarad [96]

The answer is pili. the specific type of pili that can exchange genetic information is conjugative pili. when bacteria exchange geetc information, this process is called bacterial conjugation. conjugative pili can also be named as sex pili because they also allow exchange of genes
