Ingestion of foreign substances by macrophages and yeast cells by an amoeba is known as <u>Phagocytosis</u>
<u>Explanation:</u>
Phagocytosis that is the name given to the process of ingestion of foreign particles by macrophages. In human body the white blood cells does this function. Macrophages is found in all the tissues. Any foreign particle entering the body is engulfed by this process hence protecting the organisms.
Once a bacteria enters the body it is at once detected and recognised as the foreign particle. Then it is attached to the phagocyte. Then it is engulfed into a vesicle called phagosome. Then this is killed by the process of phagocytosis.
Mitochondria(Mt) are the cell's "power stations" because the energy currency for the metabolic processes in the cell is synthesised inside this organelle via aerobic respiration. This process is known as oxidative phosphorylation. Mt is a double membraned, semi-autonomous organelle.
The mitochondrion's structure is specially tailored to the function it performs:
- The outer membrane contains carrier proteins that allow pyruvate produced during glycolysis to be transported from the cytoplasm.
- The electron transport chain(a series of protein complexes) and ATP synthase are located in the inner membrane to transfer electrons and ATP production respectively.
- The inner membrane is folded into numerous pockets called cristae, which raises the surface area: volume ratio.
- When proton accumulation occurs, the small intermembrane space between two membranes increases the hydrogen gradient.
- Matrix is the core chamber containing the necessary enzymes and pH for the Krebs cycle(oxidation of acetyl-CoA derived from pyruvate) to take place.

The key factor that influences BAC(blood alcohol concentration) would be <span>all of the above.
Height and body weight would increase the total amount of your body volume. The more your blood volume, the less alcohol concentration will be. Consuming food also delay alcohol absorption and make alcohol peak concentration less high.

Answer:
C.
Explanation:
So, a pathogen is something that causes disease, like a virus like the rhinovirus, which causes the common cold.
The goal was to orbit a spacecraft around the Earth. It has people in it. So the answer is B.
