- Forest fires reduce the number of trees that remove carbon dioxide from the atmosphere.
Answer:
B. Mutualistic bacteria in the hindgut of the termite digest the cellulose into sugars
Explanation:
Cellulose is a polysaccharide, cell walls of plant cells are made of cellulose. Termites eat cellulose and live on cellulose for their energy needs. Termites chew dead wood, but for its digestion termites depend on bacteria and protozoa which are present in their gut. They provide enzymes which can digest the cellulose of wood. Thus, they are in mutualistic relationship with termites. These microbes may starve ouside the termite body.
Answer:
The correct answer is d Insulin initiates a protein kinase cascade that utilizes glycogen synthase kinase.
Explanation:
During muscle contraction glycogen degradation occur which result in the formation of glucose-6-phosphate that is supplied to the muscle.This total phenomenon is signaled by steroid hormone epinephrine that deals with the breakdown of glycogen.
But the peptide hormone insulin exhibit the opposite effect that to stimulate glycogen synthesis by activating the catalytic activity of glycogen synthase through the help of phosphorylation by glycogen synthase kinase.
