Answer:
Green house gases like carbon dioxide, carbon monoxide, carbon tetra chloride, methane, sulphur dioxide, nitrogen dioxide, etc .. are responsible for Global warming and Chlorofluorocarbons and nitrides of oxygen are responsible for Ozone layer depletion.
Explanation:
One of the first things the IPCC concluded is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, buildings, factories, and power plants. The gas responsible for the most warming is carbon dioxide, or CO2.
Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion. The total amount of effective halogens (chlorine and bromine) in the stratosphere can be calculated and are known as the equivalent effective stratospheric chlorine (EESC).

Explanation:
The hydrogen bonding that created its hexagonal shape....the molecules get closer together and there will be more hydrogen bonding making it solid
If a somatic human cell is about to divide, then it has 92 chromatids. this is because there are 23 pairs of homologues chromosomes in a cell, one is given by both parents. when a cell divides my mitosis, the pairs separate into 46 chromatids, each one that is replicated which gives you 92 chromatids.
