The cholera toxin, an AB exotoxin, attaches an ADP-ribose group to the host's stimulatory G factor (Gs). The normal function of

SCORPION-xisa [38]

<h2>b) option is correct </h2>

Explanation:

Some bacterial toxins cause disease by altering the activity of G protein, cholera toxin is one of them
Cholera toxin catalyse ADP ribosylation of Gs and blocks GTPase activity thus Gs GTP become permanently active
Constitutive activation of Gs protein continuously induce adenylyl cyclase, cytosolic cAMP level rises that leads to activation of protein kinase A (pKA)
Activated pKA catalyse phosphorylation of two transmembrane proteins of intestinal epithelial cells:
CFTR cause excessive outflow of Cl- ion and Na+ H+ exchange cause efflux of Na+ ion, both enters in gut and form Na+ Cl-
Na+Cl- leads to outflow of water from the gut, resulting in diarrhea and dehydration and this condition may cause death of organisms due to loss of water and ions

Plzzzz help Creating models to examine concepts is important in science. Some of these are experiments

Nady [450]

Knowing that a model is considered a representation of something, the correct option is option B, in which the apple represents the Earth.<em> An apple is sectioned into quarters to represent the ratio of water to land on Earth.</em>

--------------------------------

To answer this question, you can think about a model as a representation of something.

A scientific model can represent an object, a system, a process, a phenomenon, etcetera.

Models are used to explain, predict, or describe natural events. They constitute a significant tool in modern science and are essential to scientific practice.

Knowing this, among the provided options, the one that is a model is <u>option B. </u>

<em>The apple is representing the ratio of water to land on Earth. </em>It is a representation of the earth.

All the other options are experiments performed to see what is going to be the result.
