Ascorbic acid is a vitamin used by?
- A. Humans, but not for most other animals
- B. Plants
- C. All animals
- D. Some Plants
Correct Answer

A. A. Humans, but not for most other animals

Explanation

Ascorbic acid, also known as Vitamin C, is a vitamin that is essential for humans but not for most other animals. Humans lack the enzyme necessary to produce ascorbic acid in their bodies, so they must obtain it through their diet. Other animals, such as most mammals, can produce ascorbic acid internally and do not require it in their diet. Therefore, ascorbic acid is specifically used by humans and not necessary for most other animals.

Vitamin D is essential for what class of people?
- A. For people who are sick
- B. For people who are diabetic
- C. For people who do not have adequate skin exposure to sunlight
- D. For people who have malaria
Correct Answer

A. C. For people who do not have adequate skin exposure to sunlight

Explanation

Vitamin D is synthesized by the body when the skin is exposed to sunlight. Therefore, people who do not have adequate skin exposure to sunlight may not be able to produce enough vitamin D. This can be due to various reasons such as living in areas with limited sunlight, spending most of the time indoors, or covering the skin with clothing. In such cases, it is essential for these individuals to obtain vitamin D through other sources such as diet or supplements to maintain their overall health.
