Part B. Please turn in typewritten answers to the following questions1. Asexual reproduction in diatoms occurs when the two valves move slightly apart andthe cell divides in a plane parallel to the valves. A new valve is formed which nestswithin the parent valve. What happens to the average cell size in a population ofdiatoms reproducing in this manner? How has diatom life history evolved to resolvethis issue of changing cell size? Explain.2. Many benthic invertebrates produce planktonic larvae. Please provide a rationale fora meroplanktonic lifestyle. That is, what are the putative advantages of spending onlypart of the life cycle in the plankton?3. Many species of zooplankton will undergo daily vertical migrations, spending thedaylight hours lower in the water column and the evening hours closer to the surface.Please speculate as to why so many species display this common behavior.

Which of the following options correctly describes the functions of both cilia and flagella? Excretion Protection Locomotion Body’s defense BENTEN: During meiosis I, pairs of homologous chromosomes align randomly along the metaphase plate before being separated. This process helps generate genetic variation in the offspring of sexual reproduction. Which of the following best explains how the random alignment of homologous chromosomes during meiosis helps generate varied offspring? Random alignment increases the likelihood of crossing over between non-sister chromatids. Random alignment results in the formation of gametes that contain different numbers of chromosomes. Random alignment increases the number of possible chromosome combinations in the gametes. Random alignment results in the formation of some diploid and some haploid gametes.
