What is the process by which wastes are removed from the body?

Excretion
Fallout
Farsightedness
Fatty acid

The correct answer is: Excretion

The correct answer is excretion. This is the physiological process through which the body eliminates waste products resulting from metabolic activities. Excretion plays a crucial role in maintaining homeostasis by regulating the composition of body fluids and ensuring that harmful substances do not accumulate to toxic levels. Other terms included in the choices refer to different concepts. Fallout relates to the residual radioactive material following a nuclear explosion, and farsightedness is a vision condition where distant objects can be seen more clearly than close ones. Fatty acids are components of fats, important in energy storage and cellular function, but they are not directly related to the process of waste removal. Thus, excretion is clearly the term that matches the described process.
