D. A section of DNA that codes for a Specific trait
Answer:
In the transition of metaphase to anaphase, the cohesin complex is cleaved by the separase enzyme in a process dependent on the activation of specific proteins that trigger posttranslational modifications (i.e., protein degradation by ubiquitination). This process of cleavage enables the sister chromatids to separate and move to opposite sides of the cell
The correct answer is the independent variable is one that you manipulate, control, or vary to investigate its effects and the dependent variable that being tested and measured in an experiment .
The simplest way to determine which variable in your experiment is the Independent Variable (IV) and which is the Dependent Variable (DV) is to put both variables in the sentence below in the correct order. "A change in the DV is caused by the IV." It is impossible for DV to cause any change in IV."
Example: Independent and dependent variables You plan a study to see if changes in room temperature affect math test scores. The temperature of the room is your independent variable. You change the temperature of the room by making it cooler for half of the participants and warmer for the other half.
