What is the difference between independent and dependent variables

Biology
1 answer:

The two main variables in an experiment are the independent and dependent variable.

An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable.

A dependent variable is the variable being tested and measured in a scientific experiment.

The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.

For example, a scientist wants to see if the brightness of light has any effect on a moth being attracted to the light. The brightness of the light is controlled by the scientist. This would be the independent variable. How the moth reacts to the different light levels (distance to light source) would be the dependent variable.

When results are plotted in graphs, the convention is to use the independent variable as the x-axis and the dependent variable as the y-axis.

Answer: <u>Capillaries </u>

Explanation: There are two kinds of vessels which carry the blood throughout the body. These are veins and arteries. Now apart from these two, there is a third type which is called as capillaries, which are the connecting vessels between arteries and veins. These are relatively thinner and allow exchange of gases between tissues and the blood. Therefore, arteries and veins are incorrect options.

Heart is the pumping organ, and its function is to pump the blood to every cell of the body, so this can't be correct option.

stealth61 [152]

Answer:

Absolute dating is a technique that uses radioactive minerals present in rocks and fossils while relative dating compare the sample in terms of age difference. However, absolute dating is more accurate because it uses half-life of an element and provides dates in years.
