The thing that differentiates baseline activities from health-enhancing activities would be that during health-enhancing activities one usually does something which increases the frequency of heart beats much more, compared to a baseline activity.
The circulatory system is also known as the cardiovascular system. They both allow blood to circulate throughout the body, transporting nutrients, oxygen, and carbon dioxide.
I hope this helps! :)
Answer:
The correct answer will be-
1. independent variable- the type of fertilizer
2. dependent variable- height of the plants
3. control group- The quadrant without any fertilizer treatment
4. Importance of control group- acts as reference to the experimental group as is performed without the key component in natural conditions.
Explanation:
A scientific experiment contains three types of variable and is divided into two types of group of samples.
The variables studied in the experiment are;
1. Independent variable: parameter which changes or is induced to change as per the demand of the experiment like the type of fertilizer in the experiment.
2. Dependent variable: parameter which depends on the independent variable and has to be studied in the experiment like the height or growth of the plant.
3. Control group: the group of samples left untreated in which the key component like fertilizer is not provided. So, the quadrant without any fertilizer treatment will be considered the control group.
What's the question if the answer is placebo just asking
