This formative assessment explores concepts of cell specialization, differentiation, and gene regulation. It's designed to test students' understanding of how genetic expression is influenced by internal and external factors.
Which statement best explains why muscle and nerve cells in the same organism perform different functions?
Select two statements that describe what occurs during cell specialization. (Choose 2.)
If oxygen levels decrease in the body, which event is most likely to occur first?
Which two examples show external factors affecting gene expression? (Choose 2.)
A body cell exposed to high temperature begins producing heat-shock proteins that protect enzymes. What does this show about gene regulation?
Which statement describes how feedback maintains homeostasis?
During exercise, which two groups of systems work together to maintain oxygen balance? (Choose 2.)
A genetic mutation causes kidney cells to NOT sense low oxygen. What will most likely happen?
Which two outcomes occur when feedback regulation does NOT work? (Choose 2.)
A runner trains at high altitude for four weeks. When she returns to sea level, her body gradually reduces red blood cell count. Which statement best describes this process?
