Explanation:
A frameshift mutation is an insertion or deletion in a sequence of DNA which disrupts the way the code is read. It occurs when the codons undergo a disruption through the deletion or insertion of one or multiple nucleotides (given that the number removed or added are not multiples of 3) - this alters the open reading frame; the amino acids produced through translation simply occur in a different sequence.
Further Explanation:
During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:
- somatic: these only occur within certain cells, and arise from environmental factors such as UV light
- hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.

B. It was an explanation for how the earth originated.
This indicated that Photosynthesis was occurring.
Photosynthesis- Green plants employ a process called photosynthesis to produce their own sustenance. Life on Earth depends on photosynthesis. Without it, there wouldn't be any green vegetation, and there wouldn't be any creatures either. Interactive. Sunlight, <u>chlorophyll</u>, water, and carbon dioxide gas are necessary for photosynthesis.
Chlorophyll- Chlorophyll is a pigment found in certain living creatures and all green plants. It is necessary for the process of photosynthesis, which turns light energy into chemical energy. The pigment chlorophyll is what gives plants their green color.
Pigment- A chemical that may be found in animal or plant tissue and gives off a distinctive color, such hemoglobin in red blood or chlorophyll in green plants.
