Answer:
Experimental groups: type of dogs
Dependent variable: hearth rate
Independent variable: the amount of caffeine
Explanation:
The dependent variable is the variable being measured or tested in a given study, while the independent variable isn't changed by the other variables. In this case, the heart rate is dependent on the amount of caffeine, which is then the independent variable. The experimental groups are the groups exposed to the independent variable.

Which statement describes gravity, There is no define of measurement for gravity, Gravity is the force that pulls objects towards Earth's center, Objects that have a small mass will have no gravitational pull, Gravitational pull between two objects decrease as the mass of one increases.
Answer:
Gravity is the force that pulls objects towards the earth centre.
Explanation:
According to the postulation of Sir Isaac Newton, explaining Gravity using an apple falling down from a tree. He was so curious to find out why this happened. I hope this helps.
The statement which best describes gravity is that it is the force that pulls objects toward Earth's center. Thus, the correct option for this question is B.
What is Gravity?Gravity may be defined as a type of force through which a planet or any other celestial body draws objects toward its center. It is only the force of gravity that specifically keeps all of the planets in orbit around the sun. This force attracts a body toward the center of it.
According to the context of this question, it is a fundamental interaction that causes the mutual attraction between things with mass or energy.
The best example of gravity is understood by throwing a ball high in the air, it will certainly be coming back to the surface of the earth after attaining its maximum height with respect to the energy by which is thrown.
Therefore, the statement which best describes gravity is that it is the force that pulls objects toward Earth's center. Thus, the correct option for this question is B.
