Benchmark 2 Review

Mechanical waves travel fastest through solids.

Rocks are not made of cells.

Gamma Waves have the highest frequency.

Violet has the highest frequency.

All cells must have some sort of DNA.

A mechanical wave is a disturbance that travels through a medium (solid, liquid, or gas) and requires a medium to propagate.

Living things are made of cells, can grow, reproduce, and respond to their environment, while non-living things do not have these characteristics.

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

DNA (deoxyribonucleic acid) is the molecule that carries the genetic instructions for life.
