I believe it is mono-lateral because most animals are divided in half at the spine.

I don't now about this question
Answer:
Can either be a solid, a liquid or a gas
Explanation:
A solvent can either be a solid, liquid or a gas. It is the carrier medium in a solution. It is the one in which the solute is dissolved.
Although quite unusual, a solvent might also be a solid. An important application of this can be seen in the production of alloys. Alloys are mixture of metals. To produce let’s say an alloy containing just two metals, the use of a solid solvent is needed. Here, one of the two metals is known as the base metal. It is this base metal that will serve as the carrier medium for the other metal
Answer:
1.81 x 10²⁴atoms
Explanation:
Given parameters:
Number of molecules = 3 moles
Unknown:
Number of atoms = ?
Solution:
To solve this problem, we are going to use the mole concept.
1 mole of any substance contains 6.02 x 10²³ atoms
So
3 mole of propanone will contain 3 x 6.02 x 10²³ atoms = 1.81 x 10²⁴atoms
