Binomial nomenclature 02. What are the four major groups of organic molecules involved in the metabolic process? 03. Suppose the population of marine algae in Creation increased dramatically. What would most likely happen to the levels of oxygen and carbon dioxide in the atmosphere? 04. As you will learn in a later module, there are organisms down in the very deep parts of the ocean where light cannot penetrate. These organisms, however, can produce their own energy from various chemicals in their environment. Would you classify these individuals as autotrophs or heterotrophs? 05. If a single-celled organism can propel itself through the water, can you tell if it is a prokaryote or a eukaryote just by this information? 06. Distinguish between an organ and a tissue. 07. Which part of a cell allows only selected molecules to enter inside? 08. Tide pools are areas at the shorline of oceans that sometimes become isolated from the waves and thus are exposed to the sun's heat, evaporation, or rain. If an osmoregulator found itself in such a tide pool, would the composition of its body fluids change with the changing tide pool conditions? 09. Explain how a large tuna can remain active in cold water despite the fact that its body temperature changes with its environment. 10. Corals are organisms that can reproduce both asexually by individuals dividing into two identical individuals, or sexually by broadcasting gametes into the water. If you come across a colony of coral that is connected together, is it more likely that the individuals in this colony are a result of asexual reproduction or sexual reproduction? 11. Two marine organisms appear to be very similar and are bred together in an aquarium, producing offspring. The aquarium owner tried to breed the next generation a year later in order to sell their offspring, but they do not appear to be fertile. Assuming there is no problem with the water quality or nutrition, what could you suppose about the first two organisms?
