The lithosphere is largely made up of soil, minerals, and rocks—essentially the earth’s crust. A sister to the lithosphere, the hydrosphere contains the liquid parts of the earth. The cryosphere consists of all frozen water on the earth. Frozen water makes up about 75 percent of the earth’s fresh water. For the atmosphere, the system changes from water to air. The atmosphere is the thin layer of gasses surrounding the planet. The biosphere includes all living organisms, from the bottoms of the oceans to the upper reaches of the atmosphere.
Answer AND Explanation:
Mutation is a spontaneous change in the DNA. Gene mutation refers to changes in the nucleotide sequence in a particular gene while chromosomal mutation are changes in the gross structure of chromosomes.
During transcription or translation, RNAs are formed which are not heritable. Many copies of RNA are produced and a single bad one is not a big problem to the organism. Mismatch repair enzymes can fix any errors that were missed by the polymerases during transcription.
