When a plant leans toward the sun, what is this character of life
likoan [24]

Answer:

Among the seven characteristics in life, the one should be sensitivity. It is where living organisms detect and react to stimulus or changes to the environment.

Specifically among plants, this change is called a tropic response, or tropism for short. Plants reacts to aspects like light, gravity, or water.

This response is controlled by a plant hormone called auxin. Auxin is produced at the tip of the plant, and they diffuse among the plant. The auxin accumulates at the side of the plant that doesn't receive as much sunlight, and auxin can stimulate its growth on that side so the plant bends. That's how a plant bending works.

Anyways, the answer to the question should be sensitivity.

Many receptor tyrosine kinase pathways have mapk as a downstream signaling component. mapk can phosphorylate target proteins. wh
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.
