Answer:
The correct answer is option C. up-regulation.
Explanation:
When the body requires the increased level of the hormone, target cells increase the synthesis of more receptors on the cell surface of the target organ. This process is known as the up-regulation of the receptors for the hormone.
Up-regulation is an increase in the receptors present on the cell surface of target cells so that cells can easily bind to the hormone. Up-regulation makes the cells increase the sensitivity to a hormone.
Thus, the correct answer is option C up-regulation.
Answer:
Proten W
Explanation:
SDS-PAGE gel is a method used for the separation of proteins in which proteins are separated based on their length (smaller proteins move faster through the gel, due to less resistance).
When treated with proteolytic enzymes, proteins are cut and become short fragment. This means that the fragments formed after the use of proteolytic enzymes, will move faster and thus, migrate a longer distance. Proteolytic enzymes in Set 2 cells will act only on plasma membrane proteins (because they cannot penetrate), while in Set 2 they will act on both, plasma membrane and interior proteins. Control group will have only the large fragments (not treated with enzyme).
Protein W travels the same distance on a gel of proteins from Set 1 and Set 2, but different than control group. It means that the proteolytic enzyme worked the same on Set 1 and Set 2.
Answer:
<em>Staphylococcus aureus</em>
Explanation:
<em>S. aureus</em> is a toxin producer and even though the bacteria can be destroyed with heat, <em>its toxin is heat stable</em>, this means that it can survive after heating producing food poisoning. This kind of poisoning occurs in foods that require hand preparation, like the potato salad or ham in the example, especially because in the example those food were at room temperature, in the picnic, allowing the<em> S. aureus</em> to produce the toxin.
