Simple diffusion and facilitated diffusion both allow molecules to cross the cell membrane without any expenditure of energy by the cell. They are each classified as a type of passive transport.
In meiosis, a diploid parent cell divides to form haploid daughter cells.
That'd be A. The formula for photosynthesis is carbon dioxide + water + light energy = glucose + oxygen
The Sun is located
at the center of our Solar System, at a distance of about 150 x 106 kilometers from
Earth. The Sun produces solar heat energy. This energy travels through space in the form of electromagnetic
waves. The process of heat transfer is known as radiation.Before reaching the sea-level the sun's rays have to pass through the whole thickness of the atmosphere.
So, the first surface that has the potential to come into contact with solar radiation are the clouds.
Nitrogen and carbon are considered molecules
