- D.
D. When the organic compound develops
Correct Answer
C. C. When the organism cannot synthesize the compound in sufficient quantitiesExplanation
An organic compound is said to be a vitamin when the organism cannot synthesize the compound in sufficient quantities. This means that the organism is unable to produce enough of the compound on its own and therefore needs to obtain it from external sources, such as food or supplements. Vitamins are essential for various biological processes and functions in the body, and their deficiency can lead to various health problems. Therefore, when an organism is unable to synthesize a specific compound in sufficient quantities, that compound is considered a vitamin for that organism.Rate this question:

- D.
D. Some Plants
Correct Answer
A. A. Humans, but not for most other animalsExplanation
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.Rate this question:

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.Rate this question:
