The correct answer is "grey; central canal".
Explanation:
Grey matter refers to an area of the brain, brainstem and cerebellum comprised of unmyelinated neurons and other cells that has given its name for having a pinkish-grey color in the living brain. Grey matter is also present in the spinal cord in an are of three grey columns that are H-shaped and it is located around the central canal filled with cerebrospinal fluid
Answer:
Anabolic.
Explanation:
The metabolic reactions of the body are important to maintain the physiology and homeostasis of the body. Two main types of reaction in the body are catabolic reactions and anabolic reactions.
The anabolic reaction is the reactions that are involved in the formation of the large molecules from the simpler substances. The anabolic reactions are involved in the growth and repair process as complex protein and factors are required that can only be obtained by the anabolic reactions.
Thus, the correct answer is option (3).
Answer:
When the natural resources Exhausted
The purple color of potassium permanganate gradually spreads throughout the water in the jar by the process of diffusion.
- Diffusion is the process of movement of a substance from the region of higher concentration to the regions of lower concentration. Diffusion occurs in liquids as well as gases.
- Potassium permanganate is a purple color compound, when it is added in a jar of water it spreads throughout the water by the virtue of diffusion.
- The concentration of potassium permanganate is higher at one point and the other regions in the jar have its nil or low concentrations initially, this leads to the set up of a concentration gradient.
- As time passes diffusion occurs and the particles of potassium permanganate keep on migrating to the regions of low concentration until the concentration is uniform throughout the jar. Ultimately, it spread throughout the jar making the water purple.

Answer:
Food must be broken down into nutrients for the body to use for energy, development, and cell repair. Before the blood absorbs and transports nutrients to cells in the body, food and drink must be broken down into smaller nutrient molecules.
