In what ways do historical events change our attitude/valuation towards the environment?

Lapatulllka [165]

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.

Fossil seashells have been found in rock beds on land. what can you infer about how the area has changed
olga55 [171]
When we go to the beach one of the most exiting activities that we do is of course collect the best looking seashells. Now I have never seen seashells in another place other than the beach.

 My point in this entery that I have just mentioned is that where there is seeashells there is body of water. What those fossils mean is that that particular place whhere those seashells were once found means that maybe a very long whille back that place was onetime a body of water. Some natural dissaster came and that place doughtet and the water moved to some place else. 


My pleasure to help, over and out ;)
