3. Niacin.

4. Beta carotene.

5. Osteoporosis.

6. Calcium.

7. Epithelial.

8. Intrinsic.

9. Sunlight.

Step-by-step explanation:

1. Riboflavin and thiamin are important for energy production within cells, including nervous system cells.

2. Pellagra: the niacin-deficiency disease causing dermatitis.

3. Niacin: this vitamin can be produced in the body if enough tryptophan (an amino acid in proteins) is present.

4. Beta carotene: is one of the plant-based forms of vitamin A that must be made active in the body.

5. Osteoporosis: Thinning of bones that occurs in older age and results in serious fractures.

6. Active vitamin D acts on 3 key target organs/tissues in the body to raise the blood calcium levels.

7. Epithelial: Type of tissue that lines and protects the digestive tract and respiratory tract and is maintained by vitamin A.

8. Intrinsic factor, produced in the stomach, is needed for the body to be able to absorb adequate amounts of vitamin B12.

9. Vitamin D can be produced by exposure of the skin to sunlight.
