Answer:
Leaf.
Explanation:
A house has rooms. A tree has leaves. When completing these analogy exercises try to relate the words in a sentence, then test the options. For example, if you first come up with the sentence "a house has rooms," use the same structure to test out the options for "tree." There are "a tree has forests" which does not work, "a tree has plants" which does not work, so it must be "a tree has leaves."

The lens aperture is usually specified as an f-number, the ratio of focal length to effective aperture diameter. A lens typically has a set of marked "f-stops" that the f-number can be set to. A lower f-number denotes a greater aperture opening which allows more light to reach the film or image sensor.
The energy needed to break the bonds of 2 moles of O2 gas would be 968 jk/mol.
<h3>What is a chemical bond?</h3>
A bond is a term that refers to the attractive interaction between atoms and molecules.
The energy needed by moles to interact is measured in joules per mole and is represented as follows:
In the case of O2 moles, they require 494 jk/mol, therefore, if we need to separate 2 moles of O2, we need 968 jk/mol.
