Answer:
I don't know where you got the four answers from, but I just spent 5 minutes trying to find the answer. The energy is suppose to go from the chloroplast to the mitochondria, to mix with carbon to become glucose. It is, however, called the Calvin Cycle. My apologies if I'm just misinterpreting the question, but this is the answer I found.
Explanation:
He could race multiple cars with different weight added on them and do multiple races (just to be sure) and see if his theory was correct, if not he should right down what he has learned from his experience! :D
-You'll never learn if u don't try ;)
Genetic variation can be caused by mutation (which 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).
First, prophase this is when the chromosomes are just chillin in the nucleus that is protected by the nuclear envelope(the purple circle in the blue circle).
Then, metaphase this is when the nuclear envelope breaks down and the chromosomes line up on the metaphase plate in a line.
Then, anaphase this is when the two chromatids that make up one chromosome are pulled apart by spindles.
Then, telophase this is when the spit chromatids start to form new nucleus and causing the cleavage furrow, the line in between the cells that holds them together, to form.
Finally Cytokinesis, this is where you finally get your too new cells.
