Answer:
The geosphere transfers carbon to the biosphere when volcanic eruptions occur. Burning fuels like carbon dioxide, fossils, gasoline also transfers carbon from the geosphere to the biosphere.
Carbon is incorporated into the geosphere when an organism dies. The carbon then forms fossils fuels etc. which are consumed by humans. The shells becoming limestone also transfers carbon. These limestones are used by humans for various purposes.
C.) To copy a segment of DNA into RNA.
Transcription is the process of copying a segment of DNA into RNA. The outcome of transcription is a complimentary strand of messenger RNA(mRNA)
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.
