Answer:

C

Explanation:

The experimental and control group differ by <u>only one factor</u> for a scientist, and that is the independent variable.

<em>A scientist will always try to isolate the effects that are due to a variable and keep every other variable constant. The variable that is manipulated in order to measure its effect is known as the independent variable. A control group usually forms the basis for measuring the effects of the independent variable. While the independent variable is varied in experimental groups, it kept at the zero level for the control group.</em>

The correct option is, therefore, C.

Ad libitum [116K]
Spray drying is a process in which a liquid containing dissolved or suspended solids is sprayed through a nozzle into a chamber in which hot air is being blown into at the same time. As the nozzle releases small drops of the solution, it comes in contact with the hot air and the moisture content of each droplet is removed. This way, the liquid is turned to powder form which moves to a conveyor belt at the bottom of the chamber.

Asthmatic airway epithelial cells differentially regulate fibroblast expression of extracellular matrix components
quester [9]

Asthmatic airway epithelial cells differentially regulate fibroblast expression of extracellular matrix components of anxiety (low vs. high) and stress (low vs. moderate vs. high) on test.

Everyone experiences anxiety occasionally, but persistent anxiety can reduce your quality of life. Though likely best fibroblast for altering behavior, worry can have negative effects on our physical health. Anxiety speeds up our fibroblast and breathing, concentrating blood flow to the parts of our brains that need it. You are getting ready for a challenging situation by having this extremely bodily reaction. Test performance may be impacted by anxiety. According to studies, pupils with low levels of test anxiety perform better on multiple-choice question (MCQ) exams than pupils with high levels of anxiety. Studies have indicated that female students have greater levels of test anxiety than male students.
