Answer:
The correct option is : a. causing threshold to be reached more quickly
Explanation:
Norepinephrine, also known as noradrenalin, is an organic compound, which belongs to the catecholamine family. It acts as a hormone and a neurotransmitter in the brain and the body and also impacts the heart.
It is one of the hormones secreted by the adrenal medulla. Norepinephrine is a part of the fight-or-flight mechanism of the body. It acts by binding to the β-1 receptors and opens the chemical or ligand gated calcium and sodium ion channels. Therefore, <u>it causes the threshold to be reached faster </u>by increasing the rate of depolarization and thus causes heart arrhythmia.
Therefore, <u>Norepinephrine acts on the heart by </u><u>causing threshold to be reached faster.</u>
Answer:
288ng/ml
Explanation:
A serial dilution is any dilution where the concentration decreases by the same quantity in each successive step.
- Serial dilutions are multiplicative.
it to 3 rounds of dilutions for the first tube so 3x6=12 so the 300-12=288
Answer:
A. True
Explanation:
They inhibit ACE, there is no conversion to Ang II, the activation of bradykinins is inhibited and they accumulate creating adverse effects. Vasodilation of the efferent arteriole occurs in the kidney, intraglomerular pressure is decreased and secondary damage caused by hypertension can be improved.
