Answer: (Simple/facilitated) diffusion occurs across the membrane, but (Simple/facilitated) diffusion occurs through selective transport proteins. In Facilitated diffusion, molecules move (down a concentration gradient/ against a concentration gradient).
Explanation:
Answer
D. nitrogen, oxygen, and trace amounts of other gases.
Explanation:
Earth is composed of an atmosphere that sustains life. It protects its inhabitant against direct radiation from the sun that could be of adverse effect. The earth consist of Nitrogen-78%, oxygen-21%, carbindioxize- 0.04%, Argon - 0.93% and trace element such us helium, hydrogen, krypton and water vapour. The earth consist of 5 different layers this include the stratosphere, thermosphere,
Atmosphere, troposphere, Mesosphere.
Earth is the only planets that sustains life and its has the ability to accommodate different living organism because of its diverse climatic condition.
Option D is the answer because Nitrogen and oxygen are contain in large amount and otherwise trace quantity.
