What are possible benefits of studying Biology?
IRINA_888 [86]
Science means to know. Biology is the study of living things.
You understand a lot more of the function of the body (EMT, healthcare, diseases, etc.)
animals (veterinary work,etc.) You will understand the intro into genetics, and the ways in which the sun and plants directly influences our entire world.
Biology is a form of science that is pretty broad, and at the same time a form of science you can use in every day life of understanding the basic things that happen around you (in culture, family, news, environment, behavioural, etc.)
Biology is also a great way to get your feet wet into basic science- a launching pad for chemistry, physics, etc. Hope this helped. :)

Mrrafil [7]

Answer:

Independent variable: varying amounts of light

Dependent variable: plant growth

Explanation:

The variable, which are factors that can be altered, in an experiment can either be independent or dependent. An independent variable is one in which the experimenter manipulates or controls in order to bring about an outcome. For this experiment conducted by Rachel, the independent variable is the VARYING AMOUNT OF LIGHTS.

The dependent variable is the variable that responds to changes of the independent variable. In other words, the dependent variable is the outcome of manipulating the independent variable. Hence, the dependent variable is dependent on the independent variable. For Rachel's experiment, the PLANT GROWTH is the dependent variable because it is what responds to changes in amount of light (independent variable).
