Answer:
The effects of each kind of radiation is different on the molecules.
Explanation:
Microwave causes molecules that have two opposing poles to spin rapidly due to absorption of the electromagnetic radiation waves. When molecules absorb Infrared radiation, changes occur from a ground vibrational state to an excited vibrational state. When the visible light is absorbed by molecule, the electron is excited and goes to an orbital of higher energy than the lower energy. Ultraviolet radiation turns the stable molecule into a reactive species.
The periodic table was arranged by Mendeleev in the increasing order of atomic numbers. The arrangement sees to it that the elements belonging to the same column has similar properties and the rows are arranged in increasing number of valence electrons. The answer here is true.
Answer:
cellular respiration is needed for our cells to get energy from our food.
Explanation:
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
