Answer:
Try answer B that should be correct
Explanation:
Because the mouth breaks down the food and the stomach uses acid to break food down even more...
Depending on the organism, the cell can get its energy from the sun (Plant; Photosynthesis) or through ATP energy (Animal).
DNA is copied during mitosis and when the two resulting copies of DNA are compared they are found to contain the same order of nucleotides is not the result of mutation in the DNA sequence of an organism.
Explanation:
Mutation is the process
It is caused by certain chemicals called mutagens or by environmental factors.
In mutation the nucleotide get change which eventually changes the protein product.
In mutation purine base gets mutated to purine base and pyrimidine base gets mutated to pyrimidine only.
A single change in nucleotide is called point mutation and the effect occurring because of it is called frame shift mutations.
In S phase there are checkpoints which ensure that DNA replication is accurate and when mitosis follows it equal distribution of DNA takes place between the two daughter cells hence no mutation will takes place.
D. This is because artificial selection is basically the human breeding of plants or animals, and we do so in a way to bring forth the best traits to solve a problem or create a better product.
Hope this helps!
