What is "Osmosis"? A. process by which some organism use sunlight to synthesize (make) food from carbon dioxide and water.

B. the fourth and final stage of mitosis, in which the chromosomes reach two sides of a cell and are incorporated into two new nuclei

C. a type of cell division in which the resulting cells have half the chromosome number of the parent

D. the diffusion of water across a semipermeable membrane

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
