in redi's second experiment, the independent variable is presence of the gauze, or lack of it, while the dependent variable is appearance of maggots .
<h3>What are
independent variable and independent variable?</h3>
independent variable can be described as the variable that stands alone and whereby the other variables can not impact it when one is trying to measure. For instance someone's age is independent variable.
On the other hand ,dependent variable are variable that can not stand alone , hence in redi's second experiment, the independent variable is presence of the gauze, or lack of it, while the dependent variable is appearance of maggots .

Down Syndrome is caused by a chromosomal - the trisomy of chromosome 21. The non-disjunction of the homologous chromosomes during meiosis causes some of the daughter cell to have two sets of chromosome 21. During fertilization, the resulting zygote, therefore, will have three chromosomes 21. The symptoms of this genetic disorder are; intellectual disability and stunted growth.

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>
