The organic compounds that scientist use to cut, copy, and move segments of DNA

• carbohydrate

• enzymes

• harmones

• starches

In which cell structure is energy extracted from nutrients?

• chloroplast

• ribosome

• vacuole

single celled organisms are able to maintain homeostasis, even though they lack higher levels of organization such as organs and organ systems, because

• single-celled organisms do not carry out the same life processes as multicellular organisms

• multicellular organisms do not rely on tissues or organs to carry out life processes

• cell structures work together to maintain homeostasis in single-celled organisms

• single-celled organisms are able to coordinate organ functions to maintain homeostasis
