In an experimental study of the effect of copper deficiency on coat color in bicolored juvenile rats, the independent variable i
lana [24]

Answer:

amount of copper

Explanation:

<em>The independent variable would be the amount of copper fed into the experimental rats.</em>

An independent variable during an experiment is a variable whose value is not dependent on any other variable being measured in the experiment.

The value of an independent variable is not changed by any other variable in an experiment. In actual fact, the effect of the independent variable is being tested on other variables (dependent variables) in the experiment.

<u>Hence, in an experimental study of the effect of copper deficiency on coat color in rats, the amount of copper fed into the system of the rats will be varied and the effects of this variation on the coat color of the rats would be observed by measuring relevant variables. Therefore, the amount of copper is the independent variable.</u>

Disassembly of the nuclear envelope ________________. select one:
Alex777 [14]
Disassembly of the nuclear envelope must occur for kinetochore microtubules to form in animal cells. This disassembly of nuclear envelope is triggered by the cyclin-dependent kinase at the onset of mitosis. The reassembly is mediated by multiple interactions of the INM proteins with chromatin. Dephosphorylation of INM proteins at late anaphase/telophase is required for nuclear envelope reassembly.
