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.

The chemical formula C6H12O6 is the chemical formula of glucose which is a monosaccharide containing an aldehyde group (-CHO) with 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms. Glucose is a product produced from photosynthesis.
The chemical molecular formula for the photosynthesis process is 6CO2+6H2O→C6H12O6+6O2. The synthesis process is a reaction that occurs in plants to produce food to be used as energy for cells. The process of photosynthesis requires materials in the form of air which is represented by H2O and carbon dioxide which is represented by the formula CO2 in the chemical formula of the photosynthesis process. The products of photosynthesis are glucose which is represented by C6H12O6 and oxygen which is represented by O2 in the chemical formula.
Some people often refer to the chemical formula of photosynthesis as CO2+H2O→C6H12O6+O2, this formula is an unbalanced equation. Because the auction will produce glucose with the chemical formula C6H12O6 having 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms, then should the chemical formula carbon dioxide H2O and water O2 also have a total of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.

Answer:
Evidence for evolution comes from many different areas of biology:
Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.
Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.
Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).
