Nonpolar and small polar moleculescan pass through the cell membrane, so they diffuse across it in response to concentration gradients. Carbon dioxide and oxygen are two molecules that undergo this simple diffusion through the membrane. The simple diffusion of water is known as osmosis.
The correct answer is:
d.
all of the above
Explanation:
In plate tectonics, a convergent boundary, also recognized as a destructive plate boundary, is a section of active deformation where two or more tectonic plates or parts of the lithosphere are near the edge of their life cycle. If two tectonic plates strike, they create a convergent plate boundary.
In this case, the physiotherapist is using Constraint-induced movement therapy.
In Constraint-induced movement therapy, the therapist forces the use of the affected arm, by restricting the movement of the arm. In this condition, the therapist block all the possible to work with an unaffected arm, which force the person to use the other arm, and hence, it helps in restoring the movement of the affected arm.
Producers are called producers because when they take in carbon dioxide and water, and they produce glucose and oxygen. Animals need oxygen to survive and producers are the reason that all of the animals on earth haven't used up all the oxygen in the atmosphere. We need producers to survive, otherwise the Earth would be carbon dioxide rich and we humans couldn't breath it.
