Answer:
true
Explanation:
the molecules will naturally follow the concentration gradient. they will always try to flow from high concentration to low concentration. (like on a crowded elevator, you try to move away from people)
Answer:
EXERCISE
Explanation:
In an experiment, the independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable outcome.
In this case, an experiment is carried out to test the hypothesis that "exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time". The experiment contained two groups (one group sits quietly before squeezing a clothespin as many times as possible and the other does 25 JUMPING JACKS before squeezing a clothespin as many times as possible).
The independent variable is the EXERCISE (jumping jacks) that was changed for each group in the experiment.
In the chemical bonds in molecules
Answer:
Hi
The answer is:
Thiamine, Adenine, Guanine, Cytosine
Explanation:
These four are the nitrogenous bases that are integral components of the DNA molecule. These along with phosphates and deoxyribose sugar make up the DNA molecule. The Adenine always pairs with the Thiamine base, and the Guanine always pairs with the Cytosine base in a DNA molecule, through hydrogen bonds.
Hope this helps!
