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.

And at the long run, the protein will be precipitated. This is what is referred to as the 'salting out' procedure.
