independent group
responding group

computer modeling
homogenization

We'll be glad to check your answers.

For the first question, the group in an experiment that is not exposed to changes in the independent variable is called the control group. To determine the answer, you need to understand what the control group is in an experiment. The control group is a group that is used as a baseline or standard to compare the experimental group(s) to. It does not receive the treatment or manipulation of the independent variable. By comparing the results of the control group to the experimental group(s), researchers can determine the effect of the independent variable.

For the second question, the process of separating different parts of cells that have been broken apart is called centrifugation. To arrive at this answer, you need to understand what centrifugation is and its application in cell biology. Centrifugation is a technique that uses centrifugal force to separate components of a mixture based on their density. In the context of cell biology, centrifugation is often used to separate cellular organelles and other cellular components based on their size and density.
