Answer the following question given this paragraph: Cells are the building blocks of life. This is clear from the photo in Figure below . It shows stacks upon stacks of cells in an onion plant. Cells are also the basic functional units of living things. They are the smallest units that can carry out the biochemical reactions of life. No matter how different organisms may be from one another, they all consist of cells. Moreover, all cells have the same basic parts and processes. Knowing about cells and how they function is necessary to understanding life itself. Q: What are the building blocks of life? Choices: - muscles - seeds - bricks - cells A:
cells
Answer the following question given this paragraph: Q: Archaeal cell walls contain a variety of polysaccharides and proteins but lack what? Choices: - RNA - DNA - S-layers - peptidoglycan A:
peptidoglycan
Q: Answer the following question given this paragraph: During the diakinesis stage, chromosomes further condense. The chiasmata remain intact during this stage. The remainder of this stage is similar to prometaphase of mitosis: the nucleoli disappear, the nuclear membrane disintegrates, and the meiotic spindle begins to form. Q: Chromosomes further condensed in which stage? Choices: - tracheophyte stage - zooflagellate stage - zygum stage - diakinesis stage A:
A: diakinesis stage

Answer the following question given this paragraph: Figure 15.1 Fight or Flight? Though the threats that modern humans face are not large predators, the autonomic nervous system is adapted to this type of stimulus. The modern world presents stimuli that trigger the same response. (credit: Vernon Swanepoel). Q: The fight or flight response involves what system? Choices: - functional nervous system - cellular nervous system - voluntary nervous system - autonomic nervous system A:
**Answer**
autonomic nervous system
Answer the following question given this paragraph: Acceleration is a vector, and thus has a both a magnitude and direction. Acceleration can be caused by either a change in the magnitude or the direction of the velocity. Instantaneous acceleration a is the acceleration at a specific instant in time. Deceleration is an acceleration with a direction opposite to that of the velocity. Q: Acceleration is a vector, and thus has a both a magnitude and what else? Choices: - temperature - pressure - wavelength - direction A:
direction
