Final answer:
If any of the life processes were absent in a human, their ability to function would be decreased.
Step-by-step explanation:
Most processes that occur in the human body are not consciously controlled. They occur continuously to build, maintain, and sustain life. These processes include: organization, in terms of the maintenance of essential body boundaries; metabolism, including energy transfer via anabolic and catabolic reactions; responsiveness; movement; and growth, differentiation, reproduction, and renewal.
If any of these life processes were absent in a human, their ability to function would be decreased. For example, if metabolism was absent, there would be no energy transfer, leading to a lack of cellular functions and eventually cell death.
The three primary topics related to this question are human life processes, body functions, and consequences of absent life processes.
