Answer:
c.Ionic bond is formed between two metals or two non metals.
<span>The S strain of bacteria that Griffith used was virulent meaning that when injected into the mouse, the mouse would die from pneumonia The R strain was nonvirulent and did not result in the death of the mouse. When Griffith injected mice with a dead S strain of pneumatic bacteria the mice remained healthy.
I hope this helps!

Explanation:
Incomplete dominance is an intermediate effect of the dominance where the allele for a trait does not express its complete effect of a paired allele as a result both the alleles show their equal effect on the trait.
The generations are produced having a third trait as observed in the case of snapdragon flowers. In the case of flowers
The allele which
1. Determines the red color will be- R
2. Determines the white color will be- r
The monohybrid cross will have parents with genotypes:
1. Red flower- RR
2. white flower-rr
The F₁ generation will have offsprings with genotype-
RR X rr = Rr (Pink flower)
The F₂ generation will have offsprings with-
Rr x Rr= RR, Rr and rr.
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.
