- What is the scientific name of the locust causing havoc to Africa?What is a sporophyte? A diploid plant that undergoes meiosis A haploid plant that produces gametes via meiosis A diploid plant that produces gametes via mitosis A haploid plant that undergoes mitosisWhat is the common ancestor of the Galapagos finches? What are the thirteen Galapagos finches? What characteristics make each of the thirteen finches a distinct species? How is each finch isolated from the others? What habitat does each finch live?
- Researchers working in a Brazilian rain forest recently discovered eight species of bioluminescent mushrooms at a single site. The mushrooms continually emit a faint glow that, although undetectable in daylight, makes them visible at night. Suggest a mechanism by which glowing in the dark could benefit a mushroom. Why do you think so many species with this unusual trait live in the same region?What do you think would happen to the phenotypes of the peppered moth if the tree bark was significantly darkened again by disease or pollution?A number of different, unrelated species of Arctic fishes have evolved an adaptation to avoid freezing in frigid, winter waters. These different species all use the same glycoprotein that they circulate through their blood to prevent ice crystals from forming in their bloodstream. What is the adaptation of freeze resistance in these fishes is an example of? Parsimony Paraphyly Homoplasy Synapomorphy
- What will happen to the two Canthium species in terms of outgroup comparison?What is an archipelagoThe biological species concept depends on the existence of barriers to reproduction. What are they? Does this species concept apply in all situations? Think of an example from nature where the biological species concept would NOT be that applicable. Which species concept would be better in this example? How does speciation occur? What environmental factors might contribute to speciation? Can an individual speciate? Use terminology for the two kinds of speciation we have learned about. What is “gene flow”? What does it mean if there is NO gene flow? Two groups of individuals are separated by either side of a canyon. One researcher found that they do not cross the canyon at any point. The group on the north side have fluffy tails and thicker coats, and they do not eat moss. The south side individuals eat moss almost exclusively, have a thin coat and tail, but otherwise are generally identical. When in the lab they mated successfully, and the offspring of that mating also mated…
