Answer ;

Phagocytosis is when smaller organisms or other food particles are eaten.

Autophagy is when a damaged organelle or small amount of cytosol becomes surrounded by a double membrane and a lysosome fuses with the outer membrane of the vesicle.

Enzymes break down the material. Food vacuoles fuse with a lysosome, whose enzymes digest the food.

Explanation;

-The Lysosomes are organelles that are responsible for intracellular digestion. Lysosomes are vesicles that contain hydrolytic digestive enzymes capable of breaking down large molecules into smaller ones.

-There are several ways in which different varieties of macromolecules may be digested by lysosomes. One mechanism is phagocytosis, the other is autophagy, which entails the removal of membrane-bounded organelles or other cytoplasmic components through the action of lysosomes, and lastly the hydrolytic enzymes may break down or digest the unwanted materials.

Lynna [10]

When looking at a Neuromuscular Junction (NMJ), we know that neurotransmitters (NT) are released from the presynaptic cell and they then bind to the receptors that are located on the postsynaptic cell - this causes the effect of the NT being released.

So we are told that NT are still being released, however they are not having an effect. This would mean that they are probably being blocked by something - in this case, it seems that the neurotoxin is the culprit in the blocking of these receptors.

Therefore, if the NT cannot bind to the receptors on the postsynaptic cell, they are not going to have any effect, no matter how much NT is being released.

So the answer in this case is: The neurotoxin is most likely C) Blocking the receptors on the postsynaptic cell.

irina [24]

Answer:

Increases homocysteine levels

Explanation:

Homocysteine is an aminoacid that is resent in our blood already. This is mostly increased in our blood due to increased consumption of meat and other potential reasons, such as smoking.

High level of this aminoacid are linked to the development of heart diseases. This is because a high homocysteine level causes development of heart diseases along with other risks of renerl diseases.
