What process keeps the amounts of molecules inside and outside the cell in balance
Kamila [148]

Answer:

Diffusion

Explanation:

Diffusion is the process through which molecules in the cell are kept in balance with those outside the cell.

Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration.

Through the above mechanism, molecules having higher concentration in the cell move out of the cell and vice versa thereby maintaining the balance of molecules in and outside the cell.

The density of gas particles in a section of Earth’s atmosphere decreases. Which of the following is the most likely explanation
aalyn [17]

Answer:

<em>A. The air pressure in that section of Earth’s atmosphere decreased. </em>

Explanation:

In the free air, the density of the air diminishes as the air is warmed. On increasing the pressure, the density also increases. The air is packed. The density increments as pressure increments.

The thickness and density of air decline with the increase of height because of that the surface area of the Earth's climate diminishes with increase in height, along these lines gas particles can spread out.

The density of the air is most minimal at a high rise on a hot day when the pressure of the atmosphere is low.
