Which statement best explains why muscle and nerve cells in the same organism perform different functions?

They have different DNA.

They copy DNA from other cells.

They gain new chromosomes during development.

Low oxygen at high altitude

A body cell exposed to high temperature begins producing heat-shock proteins that protect enzymes. What does this show about gene regulation?

Heat removes unused DNA from the cell.

Temperature breaks down proteins permanently.

The cell stops all gene activity.

Which statement describes how feedback maintains homeostasis?

Feedback increases mutation rates.

Feedback only works in one organ system.

Oxygen levels stay balanced automatically.

DNA stops making proteins permanently.
