<span>Answer: Opening of Na+ and K+
Explanation:
Acetycholine binding opens Na+ and K+ ion channels in the receptors that allow simultaneous passage of Naâş into the muscle fiber and Kâş out of the muscle fiber. More Naâş ions enter than Kâş ions exit, which produces a local change in the membrane potential called the end plate potential.
Binding of acetycholine to receptor proteins opens Na+ and K+ channels resulting in jump in resting membrane potential(RMP) from -90mV to +75mV forming an end-plate potential (EPP).</span>
Answer:
spores
Explanation:
plant body grows and eventually produce spores through meiosis.These spores divide mitotically to produce haploid (having a single set of chromosomes)
Answer:
A.
Explanation:
When freshwater is met with the ocean salt is diluted to the freshwater. Therefore organism that require little salt would be put at a threat.
