Vacuoles, they ares used for storage and are always larger in plant cells.
C. Sending a message to the pituitary gland to start producing a hormone when the levels in the body are low.
Answer:
GlnA will be overexpressed and the cells will have more glutamine than glutamate
Explanation:
Glutamine synthetase (glnA) is an enzyme involved in nitrogen metabolism that catalyzes the amidation of glutamate to glutamine. Moreover, the phosphorylated form of the NtrC response regulator protein (NtrC~P) acts as a transcriptional activator of genes associated with nitrogen metabolism, including glnA. NtrC~P exhibits 1-an enhanced DNA binding activity (increased oligomerization on the target DNA template) and 2-ATPase activity (oligomerization of the NtrC phosphoprotein), which are fundamental features for transcriptional activation. In consequence, it is expected that a higher level of NtrC~P (due to a defective form of the phosphatase that dephosphorylates NtrC~P) leads to the overexpression of glnA, thereby increasing glutamine levels and simultaneously decreasing glutamate concentration.
Answer:
B.
Explanation:
It isn't any of the others and the competitive exclusion principle talks about how two similar species cannot coexist under the same resources for long. I suppose you could conclude they were trying to fullfill the same niche, but only under the assumption of comp. exclusion. So just B.
