What dose shining light through a prism show?
answers:
Light can be magnified
Light moves in a straight line
Light can be changed into heat
Light is composed of many different colors
answers:

Light can be changed into heat
Light is composed of many different colors
The correct answer is:
Light is composed of many different colors.
Light is composed of many different colors.
Are you sure?
I apologize for the confusion. Let me clarify:
Shining light through a prism shows that light is composed of many different colors. When white light passes through a prism, it gets refracted and separates into a spectrum of colors, known as a rainbow. This phenomenon demonstrates that light is made up of various wavelengths and colors.

How dose Gregor Mendel's work with pea plants affect human life today?
answers:
People continue to cross pea plants to fix Mendel's many experimental mistakes.
People use Mendel's knowledge of DNA and chromosomes to create new species.
People use strains of pea plants that Mendel developed as a major food source.
People continue to selectivity breed plants and animals to produce predictable results.

What is the main cause of earths global winds?
answers:
The equator receives more direct incoming solar radiation than the poles
The depletion of the ozone layer causes more UV radiation to escape from earth
The air, water, and sand on earth are evenly heated at the equator and the poles
The average kinetic energy of air molecules decreases when solar radiation is received
