1) Both have molecules or atoms
2) Both occupy space and have mass
3) Both can be ionized
4) Solids conduct electricity similarly gas can also conduct electricity in discharge tube under low pressure
5) Both have densities
The correct answer is the Tyndall effect. This is also known as the Tyndall scattering. It is the light scattering by the particles in a colloid or in a suspension. This phenomenon is used to determine size and density of particles in colloidal matter.
The correct answer would be that they have more MASS per volume than air.
41. Mercury,Venus, Earth,mars,Jupiter, Saturn,Uranus and Neptune
42. Nebula - Their birth places are huge, cold clouds of gas and dust
Answer:

Explanation:
Aly's teacher said some bacteria can be as small as 0.00365 cm long.
In this problem, we need to write the length of the bacteria written in scientific notation. Any number can be written in the form of scientific notation as follows :

a is a real no and b is an integer
In the given number, there are two zeroes before 3. We need to shift the decimal after 3. It can be done as follows :

Hence, this is the required solution.
