Lab 12: Meiosis kimberleigh Lewis Biology 1408-63400 Consider the Concepts Experiment: 1. A common misconception about meiosis appears when students identify which of the two divisions converts a diploid cell into two haploid cells. Meiosis I is the division immediately following DNA replication and replication does not occur again before meiosis II. However‚ meiosis I is the "reduction" division when a diploid cell forms two haploid cells. If the DNA duplicated before meiosis I‚ how

moist gas exchange surface ensures the gases can be dissolved. Thirdly‚ the membrane through which gases diffuse must be thin. Gas exchange is driven by concentration gradients. Diffusion is the process which moves the gases. The rate of diffusion is determined by the concentration gradient and the distance so having a smaller distance for the gases to travel increases the rate at which gas exchange can occur. A thick membrane would mean a slower rate if diffusion because the gases have to travel further
