Water and those Pointy things
Two species of sea urchins live practically side-by-side in sandy bottoms. The two species appear to have the same diet: drift seaweeds and other bits of organic matter. They can live in the same environment without competing.
As it compels them to live in the same environmental surroundings so the characteristics of living nature also get developed as their current following situation that's helping them to get the same food & habitat.
Answer:
I don't understand it I am so sorry
The right option is; a. It is rich in minerals from volcanic deposits.
Volcanic soil (andisol) is a light and fluffy soil that is formed from volcanic ash and cinder deposits. Volcanic soil is very fertile because it is highly composed of non-crystalline minerals, such as allophane and imogolite from volcanic deposits. These minerals create strong bonds with organic matter which leads to the accumulation of organic matter in the soil. Volcanic soil has high water retention capability and it supports the growth of crops such as rice, maize and fruits.
The volume of the gas expansion is 0.71 liters.

Boyle's law</h3>
Boyle's law states that the volume of a given mass of a gas is inversely proportional to its pressure provided that temperature remains constant.
P₁V₁ = P₂V₂
where;
- P₁ = 30 psi
- V₁ = 0.35 liters
- P₂ = 1 atm = 14.7 psi
The volume of the gas expansion is calculated as follows;
