What, generally, is the current level of deforestation in the United States? In developing nations? How would you expect the deforestation in developing nations to change in the next 100 years? Explain.

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).

since there are no options posted i'll give you a few examples.

a dolphin's flipper, bird's wing, cat's leg.

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
