Answer:
A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound.
Answer:
Flat surface parallel to mesophyll walls position
Chloroplast assumed this position in condition <u>of low light intensities or optimum light intensities</u> for the reception of maximum amount of incident light. necessary for photosynthesis
Perpendicular to the incident light position.
During condition of <u>extreme high light intensit</u>ies chloroplast aligned in this position to avoid the loss of electrons from the chlorophyll from absorption of photons; (PHOTOXODATION.)
Basically photooxdation is a wasteful process which destroys the plants.
Explanation:
Is it talking about their sugars? I need a little more detail..
The answer is: contribute to ozone depletion.
CFC (chlorofluorocarbon), including freon, is used as the aerosol propellant. <span>An aerosol is a suspension in the gaseous form of solid or liquid particles. when these compounds reach the stratosphere, UV light affects them and they release chlorine atoms. Chlorine atoms are capable of breaking down ozone molecules. With fewer ozone molecules, the ozone layer becomes thinner and harmful UV light passes through it. </span>
