galben [10]
The right answer is: vitamin C and choline
Choline (vitamin B4) is the precursor on the one hand acetylcholine (important neurotransmitter and neuromodulator) and on the other hand, the cascade initiated by betaine (intermediate in the biological methylation and precursor of membrane lipids). In this, it is considered, by extension, as an integral part of the family of B vitamins,
Vitamin C protects against cellular aging, is essential for the immune defenses and increases the assimilation of iron of plant origin. It also contributes to the formation of collagen. Its deficiency leads to a disease called scurvy (hence the ascorbic acid name of vitamin C).

what will happen if one of the levels in the biological organization will not perform its function properly?​
Sedaia [141]

Answer:

It would affect the functionality of the other levels including the organism

Explanation:

The level of biological organization is a hierarchical step consisting of how a multicellular organism forms. According to this level of organization, CELLS are the simplest unit of life and the collection of cells with a similar function is termed TISSUE. Tissues form ORGANS, organs form ORGAN SYSTEMS and finally, a collection of all the systems in the body forms the ORGANISM.

Based on this, one would observe that each level is related to the next in such a way that one forms from the other. Hence, if one of the levels in the biological organization will not perform its function properly, the other levels will be affected. For example, if the kidney cells do not perform it's function, it would affect the functionality of the kidney tissues, kidney organ, the excretory system, and the organism at large.
