Mendel knew that the variations in the offspring generations resulted from his experiments because he
sasho [114]

Mendel was able to attribute the variation observed in the offspring of his experiment to the controlled fertilization process.

Mendel was able to control pollination and, thus, the fertilization process in the pea plants used for his experiment.

Mendel was able to effectively predict the outcome with self-pollination or cross-pollination with different results coming from each. Thus, he logically concluded that the variation observed in the offspring of his crosses is due to the fact that he controlled the fertilization process.

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.
