Answer;
-Endocytosis
Explanation;
-Endocytosis includes; phagocytosis, pinocytosis, and receptor mediated: Endocytosis brings substances into the cell, plasma membrane surrounds the substances to be taken in, encloses them in a membrane-bound sac (vesicle) and brings them into the cell
-Phagocytosis: endocytosis of large solid particles (“cell eating”)
-Pinocytosis: endocytosis of extracellular fluid that contains dissolved solutes (“cell drinking”)
-Receptor-mediated: highly selective, ligands bind to specific receptor proteins on the plasma membrane and are then taken into the cell
-Exocytosis: the reverse of endocytosis: substances are removed from the cell; vesicles fuse with plasma membrane and release their contents into the extracellular fluid; important in nerve cells to release neurotransmitter and secretory cells to release cell products (ex. digestive enzymes, protein hormones).
Answer: how a virus differs from a cell...
It doesn’t contain any kind of cytoplasm, cell wall, cell membrane, ribosome or mitochondrion.
It doesn’t have any sort of metabolic enzyme of its own. So, no nutrition system is seen.
It can’t reproduce itself, without any help of the host living cell.
It can be crystallized, centrifuged or diffused.
It doesn’t have any sort of somatic development.
Chemically, its just a fusion of protein and nucleic acid. So, this characters differ a Virus from a living cell.
Explanation:
Yes, blood doping can improve your performance. Red blood cells contain lots of oxygen, thus, by filling your body with this oxygen-rich blood, you gain a lot more endurance and strength.
Let’s think about this, we can already cross out D because that is the small intestine’s function, that isn’t a picture of the small intestine.
We can also cross out A for the answers because the gallbladder is the organ that creates bile and that once again isn’t the picture of that organ.
That leaves C and B.
The stomach produces pepsin and makes hydrochloric acid, this isn’t a picture of the stomach, so that leaves you with C.
The answer to your question is C, since this is a picture of the pancreas, and the pancreas’ job is to produce enzymes that breaks down carbohydrates.
Specifically, urease catalyzes the hydrolysis of urea to produce ammonia and carbamate, the carbamate produced is subsequently degraded by means of spontaneous hydrolysis to produce another molecule of ammonia and carbonic acid. [1] Urease activity tends to increase the pH of the medium in which it is due to the production of ammonia. It is produced by bacteria, fungi and several higher plants. Urease, functionally, belongs to the superfamily of amidohydrolases and phosphotriesterases. [2]
