Knee flexion exercise is an exercise that involves bending the leg at the knee joint, thereby reducing the gap between the lower leg and upper leg.
The benefit of this exercise includes:
- Helps to strengthens the muscles in the back of the thigh.
- Helps to strengthens the muscles at the hamstrings.
The voluntary action that i may perform after experiencing fatigue from the exercise is to Stand Upright.
The action will helps my lower leg and upper leg to regain normal posture, thereby reducing the muscle tension around my knee.

Specific chemicals are bound by carrier proteins and transferred on one side of the membrane. The conformational changes they go through next enable the molecule to cross the membrane and exit on the other side.
How carrier protein facilitate the diffusion?
When a molecule diffuses, it usually moves from a high concentration location to a low concentration area until the concentration is the same everywhere in the space.
Contrary to channel proteins, another form of membrane transport protein that is less selective in the molecules it transports, carriers are proteins that move a particular material through intracellular compartments, into the extracellular fluid, or across cells. Carrier proteins are found in lipid bilayer cell structures such cell membranes, mitochondria, and chloroplasts, just like other membrane transport proteins.
Therefore, carrier proteins can facilitate the diffusion of glucose or other substances into the cell.

Explanation:
Changes in groups of organisms over time produce variations in a population. This relates to both macroevolution and microevolution.
These are evolutions within a small group or a population and across the whole species.
Answer:
3 ways to understand the differences between compounds and mixtures are described below in explanation.
Explanation:
1. In a mixture, no new product is formed. It is a simple tacking of two molecules without any chemical reaction occurring. For example water and sand. Compound is a new substance formed by chemical reactions occurring between various molecules. For example, carbon and oxygen combine to form carbon dioxide.
2. A compound is always homogeneous whereas a mixture can be homogeneous or heterogeneous.
3. Compounds have a fixed boiling and melting temperature. Whereas, mixtures do not have a definite melting and boiling temperature.
