Explanation:
Although Darwinian ideas are purely biological and scientific, they have aided theoretical research in other sciences as well, psychology, in particular. The theory of evolution does not only explain the evolution of the human body, but also that of the brain. The brain's psychological mechanisms and the behaviors they produce can largely be understood through Darwin's theories; the theories of natural and sexual selection have directed much of psychological research.
In general, scientists accept Darwin's theories but in specific fields, such as social psychology and neuroscience, scientists have formulated surprising explanations using Darwinian ideas.
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.
