It is because of the different neurotransmitters and their receptors.
Sympathetic stimulation of arterioles in skeletal muscle is mediated by epinephrine acting on its β-adrenergic receptors.
Sympathetic stimulation of vasoconstriction occurs as a result of activation of α-1 adrenergic receptors by norepinephrine released by post-ganglionic sympathetic neurons.
Answer:
The initial step of producing protein in a pig kidney artificially may involve the study of number mRNA produced by kidney.
Explanation:
As the protein is produced mainly in the kidney by studying the mRNA produced in it. It shows the locations of kidney elevated proteins such as the – proximal tubules, glomeruli etc. The maximum amount of proteins is seen in the genes, present in the kidney.
The whole system of kidney shows that the gene expression is shared mostly with the liver. So while producing the artificial protein in pig kidney, the number of mRNA should be considered.
Answer:
Explanation:Motion is when an object moves from one place to another, while force is what causes an object to move or to stop moving. Examples of force include the kick that causes a ball to move across the field and the gravity that slows and eventually stops that ball from moving.
Answer:
The positive control should give a large amount of enzyme activity, while the negative control should give very low to no activity. If the positive control does not produce the expected result, there may be something wrong with the experimental procedure, and the experiment is repeated.
