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.

Answer:
B. It washes minerals from the topsoil.
Explanation:
“leaching” refers to an agricultural process in which a liquid, typically water, percolates through the soil and drains it off soluble minerals, chemicals, and or nutrients. Leaching affects some soils more than others depending on factors like its soil structure and external environment.

Answer:
hypertonic; loses water
Explanation:
The extracellular fluid that has higher concentration of solute particles relative to the cytosol of the cell is called hypertonic solution. Thus the less concentrated solution inside the cell is called hypotonic solution.
When the <u>cell is placed in a hypertonic solution</u>, <u>water diffuses from the inside of the cell to the outside</u> i.e. from a region of low solute concentration to a region of high solute concentration, through the cell membrane due to osmotic pressure. <u>Thus causing the cell to shink and get wrinkled.</u>
<u />
<u>Therefore, when a cell is placed in a hypertonic solution, it loses water and gets wrinkled.</u>
