 <span>The control group would not receive any medication or they would be given the salt solution without any drugs with it (basically a placebo). 

A dependent variable is a variable dependent on another variable: the independent variable. In simple terms, the independent variable is said to cause an apparent change in, or simply affect, the dependent variable. 

The variables you have are what the rats are feed (their diet), number in cage, size of the cage (things such as a smaller care with more within it should cause undue stress), what they are exposed to within their environment. Even things sun as amount of light within the room, the temperature of the room, etc. </span>

List 4 ways in which you can decrease your chances of catching the flu or cold
shutvik [7]
Hi there!

#1 Washing you’re hands after touching anything that may be dirty, or even just using the restroom.

#2 Disinfecting door nobs, handles, desks and things you may touch on a daily basis.

#3 Stay away from those you may think are sick.

#4 Having those around you remember to cover their mouths and noses while sneezing.

Remember to do this using the pit of you’re elbows NOT you’re hands. This can spread germs more easily.

Hope this helps you!

What is the percent of the genes on the chromosome?
kati45 [8]
Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people. Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.

Hope this helps
