D. Meiosis is the only source of genetic variation for sexual reproduction
Explanation:
Sexual reproduction is the form of reproduction that involves two parent organisms which produce gametes or sex cells that unite while asexual reproduction involves only one parent to occur. One advantage of sexual over asexual reproduction is that there is room for genetic VARIATION among offsprings produced.
However, this genetic variation occurs in sexual reproduction as a result of a process called CROSSING OVER in MEIOSIS. Meiosis is the only division that produces gametes in living organisms and it only occurs in sexually reproducing organisms.
Biomes are typically not classified by temperature, because some biomes can experience extreme temperatures from one season to the next. Other biomes might have a more consistent temperature throughout the year.
