The melting of the ice caps makes Earth warmer because less solar energy is reflected due to loss of Albedo
Answer:
lactose, repressor, RNA polymerase (or mRNA might fit here), transcription, repressor, RNA polymerase
Explanation:
Hope this will help.
Maybe because of global warming and the glacier water melting makING it bigger and deeper. (I hope this is the answer you are looking for)
<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
