<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>
<span>The answer is autosomes.
</span>In
a human diploid somatic cell (2n), there are 22 chromosomes
present in two copies and 1 pair of sex chromosomes. This means
there are 23 pairs of chromosomes - 22 pairs of autosomes and 1
pair of sex chromosomes. <span>There are in total 46 chromosomes (23 pairs
in 2 copies: 23 × 2 = 46).</span>
Answer:
What happens after water particles returns to the ocean is that it'll evaporate over the island, and precipitation happens :3
Explanation:
:3
Atoms in molecules share pairs of electrons when they make ionic bonds.
The correct answer would be option A. Leafy gametophytes. The feature that differentiates mosses from liverworts and hornworts are the leafy gametophytes. A gametophyte is a multicellular haploid generation which is involved in the process of alternation of genes along with a diploid generation called as sporophyte.
