Question

question ① which of the following is true of an aging tissue? select all that apply less efficient tissue maintenance epidermal cells proliferate decrease in the rate of metabolism more fragile connective tissue

Explanation:

• For "Less efficient tissue maintenance": As tissues age, the ability of cells to repair and maintain the tissue declines, so this is true.
• For "Epidermal cells proliferate": In aging, epidermal cell proliferation (growth and division) actually slows down, so this is false.
• For "Decrease in the rate of metabolism": With aging, cellular metabolism (chemical reactions in cells) generally decreases, so this is true.
• For "More fragile connective tissue": Aging connective tissue (like collagen changes) becomes more fragile, so this is true.

Answer:

• Less efficient tissue maintenance
• Decrease in the rate of metabolism
• More fragile connective tissue
