Answer:
A, gamma rays
Explanation:
Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.
When cells need to gain or get rid of certain things, diffusion is a form of passive transport that does not require a cell to expand any energy.
Answer:
0.112 M.
Explanation:
- Molarity is the no. of moles of solute in a 1.0 L of the solution.
M = n/V.
<em>M = (mass/molar mass)solute x (1000/V of the solution).</em>
mass = 127.62 g.
molar mass = 286.138 g/mol.
V of the solution = 4.0 L = 4000.0 mL.
<em>∴ M = (mass/molar mass)solute x (1000/V of the solution)</em> = (127.62 g / 286.138 g/mol) x (1000 / 4000.0 mL) = <em>0.1115 M ≅ 0.112 M.</em>
