Answer:
<u>23</u> chromosomes
Explanation:
Each daughter cell <u>will have half of the original 46 chromosomes</u>, or 23 chromosomes. Each chromosome consists of 2 sister chromatids. The daughter cells now move in to the third and final phase of meiosis: meiosis II.
<span>Nicotinic acetylcholine receptors (nAChR), are <span>ligand-gated ion channels and they can be a Na+, K+ and Ca2+ ion channel. Since nifedipine is a Ca2+ channel blocker (Ca2+ channel antagonist), it might inhibit the response of acetylcholine (if its receptor is Ca channel).</span></span>
Theories explain phenomena, whilst laws are generalizations which characterize them.
Answer: ionotropic; metabotropic
Explanation:
A receptor can directly open the channel and exerts an ionotropic effect. The ionotropic effect takes place by the help of ionotropic receptors. These receptors are membrane bound receptor proteins which responds by the bonding of the ligand.
Due to ligand binding the channel opens and allows the movement of ions into the cells which helps in either increasing or decreasing the action potential.
The receptors can also bind to the ligand and produce metabotropic effect which means by the second messenger.
