Atmosphere and Hydrosphere are the answer. The atmosphere is a layer of gases that surrounds in the planet or other material inside the body that is held in place by the gravity of that body. There is also Atmosphere in earth or what we called Air, it is also a layer of gases. It is the whole mass of air that surrounds the earth so that we can breathe freely. Earth atmosphere contains 78% nitrogen, 0.9% argon, 21% oxygen and 0.03% carbon dioxide. Hydrosphere in the other side is all the water on the earth’s surface example are lakes, seas and sometimes including water over the Earth’s surface like clouds.
Next you should analyze the data
Water exists as a solid at or below 0 degree Celsius.
At 0 degree Celsius, water can go through a phase change, either freezing or melting, depending whether energy is given or taken away. If the temperature is below 0, water should exist as solid as the temperature is lower than its melting point. If the temperature is right at 0 degree, the water can partially be solid and liquid at the same time, during phase change.
Therefore, water exists as solid at or below 0 degree Celsius.
Mutations present permanent and heritable changes in the genome. We distinguish gene and chromosome mutations. Mutations in the level of genes are called point mutations because only one to several nucleotides are changed. These processes are known as deletion, insertion, and substitution. Deletion presents a loss of nucleotides which changes DNA sequence. When new nucleotides are embedded in the DNA chain, it is known as insertion. Substitution implies the process where new nucleotides are inserted while the ones that were present in that specific spot in a DNA molecule are deleted.
Mutations can also appear in chromosomes altering their number and structure. There are four types of mutations - deletion, duplication, inversion, and translocation. In deletion, a whole or one part of a chromosome is lost. Duplication presents an extra copy of a whole or one part of a chromosome. In an inversion, parts of a chromosome change order, while in translocation a part of one chromosome detaches and then connects to another.
