This is true. An easy example is monkeys who eat food from trees, or hide there from other predators found on land that might attack them, or they live in the trees and sleep there, or hide from things like storms and bad weather. They are not the only ones and there are many mammals that do this.

What's the function of stomata in plants

Answers

Hey There!

Stomata is the process in plants, where the plants use the suns energy and carbon dioxide from the atmosphere, and oxygen is exchanged in return.

Have A Brainly Day!

Plants use their stomata to take in Carbon dioxide and take out oxygen during photosynthesis. It's how they "breathe" if that makes it more understandable.

The octet rule suggests that atoms _____.

Answers

Answer & explanation:

The octet rule states that atoms must have eight electrons in their valence shell (the last electron distribution layer of an atom, or the outer energy level).

For atoms to have the full valence shell, chemical bonds must be made to donate, receive, or share electrons. Normally, atoms tend to share electrons until they acquire stability (complete valence shell).

Noblegases are the elements of the periodic table that have eight electrons in the valence shell, with Helium (He) the only exception, which has two electrons.

When an element reaches its stability, it means that it will not bind to other atoms, because it no longer has a tendency to gain or lose electrons, that is why we find no compounds formed by noble gases.
