Question

which of the following are effects of aging on the bodys tissues?
○ a change in tissue chemistry
○ an increased risk of cancer
○ a decline in tissue repair
○ all of the listed responses are effects of aging on body tissues.

Explanation:

• Aging causes changes in tissue chemistry (e.g., altered protein structure, metabolic changes).
• With aging, cellular repair mechanisms decline, so tissue repair ability reduces.
• Mutations accumulate over time, increasing cancer risk as cells age. Thus, all listed are effects of aging on body tissues.

Answer:

D. All of the listed responses are effects of aging on body tissues. (Note: Assuming the options are labeled A - D with the last option as D; if original labels differ, adjust accordingly, but the content is "All of the listed responses are effects of aging on body tissues.")
