Answer:
yes.
Explanation:
I believe that some form of life exists outside of our planet. the galaxy is gigantic and ever-expanding. there's a very low chance that with every planet out there, there's no other life form. Now, humans have depicted aliens in many ways. green with black eyes, brown like E.T.... some speak English and some speak a language we cannot understand. I'm not sure if the life forms that are out there would be as developed as we imagine, but anything is possible with an ever-expanding universe. I think the closest we'll ever get to finding an "alien" is a couple of cells that are "alive"
<span>Let's look at all the statements:Which of the following statements is true?

Tundras have a high diversity of species. - this is not true - compared to the rain forest, for example, tundras are not very diverse</span>

<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>
