The food sources available for a particular species in an ecosystem. Also space where they can live and reproduce, but food is the main factor.
A protein kinase that is specific to the amino acids serine and threonine is known as a mitogen-activated protein kinase (MAPK or MAP kinase; also known as a serine/threonine-specific protein kinase).
<h3>Mitogen-activated protein kinase :</h3>
A small number of cell surface receptors can ultimately generate a large intracellular response due to activation of kinase cascades.
In order to trigger an appropriate physiological response, such as cellular proliferation, differentiation, development, inflammatory reactions, and death in mammalian cells, MAPK pathways relay, amplify, and integrate information from a variety of stimuli.
Tyrosine phosphorylation, specifically numerous tyrosines on each RTK in the dimer, is how cross-linking triggers the tyrosine kinase activity in these RTKs. The term "cross-phosphorylation" refers to this action.
The activation of a MAPKKKK or MAPKKK by stimulation of plasma membrane receptors is the initial stage of signal transduction. The MAPKKK then phosphorylates two serine or threonine residues in the S/T-X5-S/T (X is any amino acid) motif of its activation loop, activating a downstream MAPKK.

Let’s think about this, we can already cross out D because that is the small intestine’s function, that isn’t a picture of the small intestine.
We can also cross out A for the answers because the gallbladder is the organ that creates bile and that once again isn’t the picture of that organ.
That leaves C and B.
The stomach produces pepsin and makes hydrochloric acid, this isn’t a picture of the stomach, so that leaves you with C.
The answer to your question is C, since this is a picture of the pancreas, and the pancreas’ job is to produce enzymes that breaks down carbohydrates.
The answer is B. this has to be 20 characters long.
A virus is an infectious particle that reproduces by "commandeering" a host cell and using its machinery to make more viruses.
