Answer:
Long before Darwin and Wallace, farmers and breeders were using the idea of selection to cause major changes in the features of their plants and animals over the course of decades. Farmers and breeders allowed only the plants and animals with desirable characteristics to reproduce, causing the evolution of farm stock. This process is called artificial selection because people (instead of nature) select which organisms get to reproduce.
I think the answer is D all of the above hope this helps
Addition mutation
This is an addition mutation because the mutated strand has an additional one nucleotide (cytosine) at the end.
Explanation:
This kind of mutation , including deletion mutations, are lethal because they cause a frameshift mutation. Frameshift mutation are a change in codon sequences downstream of a mutation. This causes different amino acids to be coded by the different codons hence changing the translated protein.

Answer: D. The olivine became the crust and the Iron melting defended the earth to become the core.
Explanation:
Earth was formed after it has went through a molten stage that led to the heavy materials sure as Iron metal moving inward to form the core, and the light materials moves toward the surface to form the crust.
The heat for the melting came from meteorite impacts which is usually very hot, the moon's impact, and the decay of radioactive elements.
Geological activity on the earth is driven from this initial source of heat at the earth's formation until now.
Because they are manmade, fish farms are not considered fisheries.
the answer is false
