Answer:
i think it might be c but i know its not A or B and im
on the fence for D so the best answer would be C
Explanation:
C is not true. Background radiation is the uniform microwave radiation remaining from the Big Bang.
A velocity and wavelength
Explanation:
When a periodic wave travels from one medium to another, its velocity and wavelength changes in the process.
A periodic wave is a wave with repeating pattern.
- When a wave crosses different medium with different densities, their velocity and wavelength changes.
- This implies that wave causes disturbances in different ways.
- This change in wavelength and velocity as a wave crosses two medium is known as refraction.
- When a wave moves from a less dense medium to a denser one, the velocity reduces and the wavelength increases.

Topic 2: Should employers have the right to learn the genetic profiles of the people they hire? Are there special considerations for employees in jobs in which there is a high risk to others, such as airline pilots, doctors, bus drivers?
maybe this depends on finfing a correlation between accidents and who caused them ... were they prone and is there a gene for prone.
