Biology 100 Quiz 1
1. Which is the smallest unit of life that can survive and reproduce on its own? x | a cell | | a molecule | | an organ | | a population | | an ecosystem |
2. The instructions in DNA are used to make x | proteins | | carbohydrates | | DNA | | energy | | homeostasis |
3. The chemical processes in the living cell are collectively called | adaptation | | homeostasis | | evolution | | respiration | x | metabolism |
4. Organisms designated producers usually obtain their energy from | other producers | | dead consumers | | decomposers | x | the sun | | all of these |
5. About 12 to 24 hours after the last meal, a person's blood sugar level normally varies from 60 to 90 milligrams per 100 milliliters of blood, although it may rise to 130 mg/100 ml after meals high in carbohydrates.
