Answer:
A.) a substance with ph between 0 and 7.
Explanation:
as acid has pH value between 0 to 7.
1-refraction
2-transmission
3-reflection
4-diffraction
<u>Explanation:</u>
Refraction is the bending of a wave when it enters a medium where its speed is different.Refraction is responsible for image formation by lenses and the eye.
Transmission of light is the moving of electromagnetic waves through a material. This transmission can be reduced, or stopped, when light is reflected off the surface or absorbed by the molecules in the material.
Reflection is when light bounces off an object.Light is reflected when there is a mismatch between materials through which the light is travelling.
Diffraction is the slight bending of light. The amount of bending depends on the relative size of the wavelength of light to the size of the opening.
It is an atom with a charge of 0 because a positive atom would be +1 charge and a negative atom would be -1 charge. So neutral would just be 0
Answer:
What system interacts to perform the functions of regulation?
Body systems interact to perform the functions of regulation, nutrient absorption, reproduction, and defense from injury or illness
