Answer:
False
Explanation:
Mass and volume are two different quantities. In fact:
- Mass is a scalar quantity representing the "amount of matter" contained in a certain substance. It is measured in kilograms (kg), which is one of the 7 fundamental SI units.
- Volume is a scalar quantity representing the amount of "three-dimensional space" occupied by an object or a substance. It is measured in cubic meters (
).
Therefore, mass and volume are two different quantities. They are related through another quantity called density, given by:

where
m is the mass
V is the volume
So the density of a substance represents the amount of mass contained in a certain volume of the substance.
Answer: Experiment.
Explanation:
Suppose that we have two related variables, A (independent) and B (dependent)
We could design an experiment where we can manipulate the value of A at will, and we also can observe how the variable B changes.
This is called an experiment, where the objective is to see how the variable B is related to the variable A, and then try to make a model that explains this relationship.
Answer:
As competition increases and resources become increasingly scarce, populations reach the carrying capacity (K) of their environment, causing their growth rate to slow nearly to zero. This produces an S-shaped curve of population growth known as the logistic curve (right).
