Insulin helps control blood glucose levels by signaling the liver and muscle and fat cells to take in glucose from the blood. Insulin therefore helps cells to take in glucose to be used for energy. If the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.
Explanation:
Actually respiration can release oxygen, carbon dioxide and nitrogen together, but the one that is in high amount is carbon dioxide.
Plants get the carbon dioxide they need from the air through their leaves. It moves by diffusion through small holes in the underside of the leaf called stomata. These let carbon dioxide reach the other cells in the leaf, and also let the oxygen produced in photosynthesis leave the leaf easily.
I think it's epidermis? IDK if I spelled that right...
Answer:
All energy in the system are either potential or kinetic.
Option A to D are true
Explanation:
Kinetic Energy is the energy in a body when the body is not at rest (i.e. when it is in motion)
Whole
The potential energy of an object is energy of the body in a stored form. This means that when the body is at rest (not moving but waiting to do work). This is seen in Option A where the ball is held motionless above the floor.
The potential energy of a body decreases when the body moves downward and the kinetic energy increases. This is seen in Option B and C.
The last option D is supported by the first law of thermodynamics, also known as Law of Conservation of Energy, which states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. The potential e ergy of the body when held motionless above the floor is equal to the kinetic energy of the body when it hits the floor.
