Mutations are changes that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.
They increase the genetic variation within a species because they can create entirely new alleles in a population, random mating, random fertilization, and recombination between homologous chromosomes during meiosis which reshuffles alleles within an organism's offspring.

I Believe the answer to your question is True.<span />
That statement is true because The amount of energy at each trophic level decreases as it moves through an ecosystem at least is 10% of the energy at any traffic levels transferred to the next level the rest is lost largely through the metabolic process as heat.
Answer:
Along the Kuroshio Current, because it is carrying water north towards melting ice caps
Explanation:
The ocean currents have the tendency to be faster when they are warmer, and to be slower when they are colder. The reason for this is that the warmer water is less dense, thus it can move more quickly, while the colder water is denser, thus heavier, so it moves slower. The Kuroshio Current moves from the lower latitudes toward the higher latitudes. As it does, this ocean current is becoming colder and colder as it gets closer to the higher latitudes, so it is becoming denser, heavier, and because of it slower. Another thing that will contribute to this current's slowing down are the melting ice caps because of the climate change, as they will make the water even colder, and the Kuroshio Current will come across this cold water, so it will decrease its speed significantly.
