- Horizontal gene transfer probably started soon after endosymbiosis. It has resulted in genes being moved from the mitochondrion to the nucleus. What is a reasonable explanation for why some genes still remain in the mitochondria? A. The products of those genes are rapidly damaged and need to be quickly replaced. B. The products of those genes are not required for organelle function. C. The ability for lateral gene transfer ended about a billion years ago and some genes simply got “stuck” within mitochondria. D. The products of those genes are only needed in the mitochondria.arrow_forwardWhich statement about slime molds is correct? A. Cellular slime molds have haploid zygotes. B. Cytoplasmic streaming helps distribute nutrients and oxygen in cellular slime molds. C. In plasmodial slime molds, the haploid condition is the dominant part of the life cycle. D. Cellular slime molds have fruiting bodies that function in sexual reproduction. E. Cellular slime molds form masses when food is scarce, but their cells remain separated .arrow_forwardThe cell walls of fungi are strengthened by chitin, a strong but flexible polysaccharide. Which of these statements about the function of chitin in fungal cell wall is TRUE? a. Chitin-rich walls of fungi improves feeding by facilitated diffusion. b. The movement of water and nutrients into fungal cells creates pressure that could cause them to burst if they were not surrounded by a chitin-rich cell wall. c. The chitin present in fungal cell wall does not impart any advantage in terms of nutrient acquisition from the environment. d. Chitinous tubular cell walls confers motility to multicellular fungi.arrow_forward
