The term "independent variable" means precisely what it sounds like. It is a variable that is independent of the other factors you are attempting to assess.
<h3>What is independent and Dependent variable?</h3>
- Dependent variables are so named because their values are explored in an experiment under the assumption or requirement that they are dependent, by some law or rule, on the values of other variables.
- The group that does not get the new medication being investigated in a clinical trial. This group is compared to the group that receives the new treatment to see if the new treatment is effective.
- Assume you want to put a new ADHD medicine to the test. One group would be given the new medication, while the other would be given a tablet that looked precisely like the one given to the others, but it would be a placebo.
- The control group would be the group that receives the placebo. A control group is the "untreated" group with which an experimental group (or treatment group) is contrasted in experimental designs.
- It is made up of research units that did not receive the treatment whose effect is being studied.

Answer:
No information can be inferred
Explanation:
Chromosome number provides no reference for establishing any relationship between organisms. The number of chromosome cannot depict whether a living species belong to plant kingdom or animal kingdom. It cannot even depict the evolutionary history of any species. Thus, the organism with lesser chromosome has not necessarily evolved from the species having larger number of chromosome or vice versa.
Chromosome number can only depict the quantity of genetic material with in an organism and hence no relationship can be established living species only on the basis of chromosome number.

The Trachea also known as the windpipe has tons of 'little hairs' called cilia in the epithelium that protect the throat. When someone smokes or breathes in gases it is destroyed and exposes the trachea. But thats another story. :)
The integumentary system (skin) reacts different on different sun intensity (different length exposure to sun).
For example, moderate exposure to the sunlight contributes to the production of melanin and vitamin D by the body. On the other hand, high exposure to sunlight can have negative health effects such as sunburn, which is an inflammatory response to DNA damage caused by UV radiation.
