Histamine is a chemical substance released in inflammatory and allergic responses. The histamine H1 receptor on target cells is
grin007 [14]

Answer:

-Histamine binds extracellularly to the H1 receptor.

-When histamine binds to the H1 receptor. the receptor undergoes a conformation change and binds the inactive G protein.

-Once the G protein is active, it binds to the enzyme phospholipase C, activating it.

-Histamine is likely hydrophilic.

When histamine encounters a target cell, it binds extracellularly to the H1 receptor, causing a change in the shape of the receptor. This change in shape allows the G protein to bind to the H1 receptor, causing a GTP molecule to displace a GDP molecule and activating the G protein. The active G protein dissociates from the H1 receptor and binds to the enzyme phospholipase C, activating it. The active phospholipase C triggers a cellular response. The G protein then functions as a GTPase and hydrolyzes the GTP to GDP. The G protein dissociates from the enzyme and is inactive again and ready for reuse.

Which statement best describes ecological succession?
Delicious77 [7]

The correct answer is it always occurs in a predictable pattern.

Ecological successsion is defined as a <em>change in the structure of species of an ecological community over a period of tim</em>e. The succession that begins in a new environment by uninfluence of pre-existing species is called primary succession. The disruption of pre-existing community because of succession is called secondary succession. Ecological succession happens in a predictable pattern. The ecological communities undergoes predictable change which creates a disturbance or initial formation of new habitat.

incomplete dominance. A heterozygous condition in which both alleles at a gene locus are partially expressed and which often produces an intermediate phenotype.
