Answer: B. Low pressure
Explanation: Low-pressure areas are places where the atmosphere is relatively thin. Winds blow inward towards these areas. This causes air to rise, producing clouds and condensation. Low-pressure areas tend to be well-organized storms.
Answer: 2
Explanation:- Mechanical advantage is the ratio of the output force to the input force.
Mechanical advantage=
Given:
Input force = 320 N
output force= 640 N

When testing diffusion over a selectively permeable membrane, the proper setup is aimed at putting different concentrations into tubes and the same water volume.
<h3>What is a selectively permeable membrane?</h3>
A selectively permeable membrane is a physical barrier that allows the passage of certain substances but not others.
The cell membrane is a selectively permeable membrane that cells need to interchange nutrients and waste with their environment.
In conclusion, a suitable experiment to show the process of diffusion in a selectively permeable membrane is to put concentrations of the solute into tubes and the same volume of solvent (water).

Extracting aluminum from bauxite ore requires 20 times more energy than extracting it from aluminum from recycled sources so therefore that is a good reason to promote its recycling starting with pop and beer cans which are things that most of us use.
