If a wave has a wavelength of 1 centimeter, it must be a(n) a) gamma ray b) microwave c) radio wave d) ray

Option B

Explanation:

The wavelength of gamma rays is very low and is nearly equal to or less than 10 Pico meters.

Wavelengths of microwave are with in centimeters with maximum wavelength ranging up to 30 centimeters

Wavelength of Radio Waves ranges between 1 mm to 100 kilometers and the wavelength of Ray is equivalent to the wavelengths of the visible spectrum which lies between 400 and 780 nanometers

Hence, option B is correct

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air

explanation:

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
