Answer:
Objective Lenses: Usually you find 3 or 4 objective lenses on a microscope. They almost always consist of 4x, 10x, 40x and 100x powers, when coupled with a 10x (most common) eyepiece lens, total magnification is 40x (4x times 10x) 100x, 400x and 1000x
Explanation:
Objective lenses come in various magnification powers, with the most common being 4x, 10x, 40x, and 100x, also known as scanning, low power, high power and typically oil immersion objectives, respectively
Answer: A. Frequency
B. Wavelength
Explanation: Electromagnetic waves are waves which can travel through the vacuum. Electromagnetic waves have electrical and magnetic component associated with them.
Electromagnetic waves are arranged in order of increasing frequencies or decreasing wavelengths.
Radio waves, X-rays, and gamma rays are all electromagnetic waves which have different wavelengths and thus have different frequencies. But they all travel with the speed of light.

The order of frequency of given waves : gamma rays > X rays> Radio waves.
The order of wavelength of given waves : gamma rays < X rays < Radio waves.
Answer:
They decompose dead things and absorb the nutrients and get their food
