Question

Dr. Lone Dove has begun studying the effects of a newly discovered hormone on aging. He hypothesizes that the new hormone protects the body's cells from deterioration by strengthening the cell wall against detrimental substances. Dr. Lone Dove is finding evidence for the ________ theory of aging.

a) Cellular clock
b) Free radical
c) Hormonal
d) Wear and tear

Answer 1

Dr. Lone Dove's hypothesis points towards the free radical theory of aging, which suggests that oxidative stress from reactive oxygen species contributes to cellular damage and aging.

Step-by-step explanation:

Dr. Lone Dove is finding evidence for the free radical theory of aging. According to this theory, aging is the result of accumulated cellular damage from oxidative stress, which contributes to age-related changes in the body. The free radical theory posits that substances such as reactive oxygen species can damage cell components, leading to the aging process and associated health issues. Several aspects of this theory suggest that reducing oxidative damage can extend lifespan, although research continues to explore the full implications of the theory.
