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:
The correct answer is - stereotype threat.
Explanation:
Stereotype threat is a conditional or temporally predicting in which individuals are likely to feel or experience themselves to be a risk of conforming to stereotype about their social groups.
In this case blacks, academic performance shows the impact of stereotype threat which is allegedly a key factor to racial for long period in academic performance.
Thus, the correct answer is - stereotype threat.
Answer The definitions are matched according to the terminology given below.
Ribosome This organelle is the site of polypeptide assembly. This two part organelle is found in endoplasmic reticulum.
Lysosome The cellular digestion and disposal of biological molecules occur inside this organelle. Mitochondrion Aerobic respiration occur in this organelle.
Endoplasmic reticulum This generally play role in cell defence.
