Final answer:
The statement is false as senescence refers to the aging process, not the body's ability to maintain stability, which is instead called homeostasis. Senescence includes a decline in the body's functions, while homeostasis involves regulatory mechanisms that maintain a stable internal environment.
Step-by-step explanation:
The statement that 'senescence is the body's ability to keep organs stable in the face of environmental stress' is False. Senescence refers to the process of aging which includes various biological, emotional, intellectual, social, and spiritual changes. It is characterized by a decline in the functions of cells, tissues, and organs over time. This decline can manifest in several ways, such as reduced elasticity in skin and other tissues, loss of muscle tone, graying hair, and a decrease in cognitive functions like memory and clarity of thought. Aging is affected by genetic makeup, lifestyle, and environmental factors.
Homeostasis, on the other hand, is the body's ability to maintain a stable internal environment in response to external changes. It is a dynamic process where various physiological mechanisms work to keep bodily functions within specific ranges, ensuring the health and stability of an organism.
