Answer:
Gene flow is the exchange of alleles between two or more populations. For this reason it is sometimes referred to as allele flow or gene migration. While migrating animals often carry new alleles from one population to another, they must interbreed with the new population for gene flow to occur. In the image below, a beetle from a population of brown beetles migrates into a population of green beetles.
Answer: Earth's rotation
Explanation:
Luis was most trying to model the Earth's rotation. As you know the earth rotates around it's axis once every 24 hours and this is why we have different times in the day because the sun shines on different parts of the Earth as it rotates.
