-low densities
-some may float on water
Hope this helps.
Answer:
Density-independent regulation
Explanation:
It is given that before the arrival of hurricane, the population of mice has stabilized.
This means the rate of birth and deaths are approximately equal.
But as the hurricane came, it disrupted this balance and would have led to a change in both the birth and death rates. This is termed as Density-independent regulation as abiotic factors and environmental factors have affected the birth and death rates
That’d be B.

Atom is the
most basic unit of matter. They are the general term used to describe pieces of
matter. But a different kind of atom makes up an element. A combination of atom of different elements
creates a molecule. For example, you have water; it has a chemical formula of
H2O. If you separate H from O, you have two atoms. Two atoms for hydrogen and
one atom for oxygen. However, they are of different elements. And when you
combine them to form H2O, you create a molecule. Another example of molecules are air. Air pressure is gravity pulling down on air molecules. Like us,
air has also mass and the pressure is brought down by the earth’s gravity
causing an increase in weight exerted on you as you descend lower into the
atmosphere. So, as you enter into the other layers of atmosphere above the
troposphere, the air pressure starts to decrease. <span>Below the atmosphere is the
hydrosphere. This is where all liquid forms are located. And since the seawater
has a greater mass than air, it has the greatest pressure. </span>
