5 Written questions

5 Matching questions

  1. spores
  2. cellular respiration
  3. synapse
  4. pioneer population
  5. endoskeleton
  1. a The gap between two neurons, spanning the space between the axon of one and the dendrites of the other. In order to pass an impulse across a synapse, neurons must release neurotransmitters.
  2. b Usually unicellular and microscopic, spores are produced by protist molds, fungi, and plants and are able to develop into new individuals. Spores are able to survive without food or water for long periods. Most fungi spend part of their life cycle as hyphae and part as spores.
  3. c The process in which the cell burns glucose to create ATP with the aid of oxygen. Cells have two different methods of turning food into usable fuel: aerobic respiration and anaerobic respiration.
  4. d An interior skeleton found in vertebrates made of bone and cartilage.
  5. e The first population to move into a geographic location and begin the process of ecological succession.

5 Multiple choice questions

  1. Term that refers to one organism eating another. Predation covers both carnivorous and herbivorous consumption.
  2. The final stage of aerobic respiration. The electron transport chain establishes an electrochemical gradient across the inner mitochondrial membrane that powers the synthesis of ATP in oxidative phosphorylation.
  3. The genetic transmission of traits from parents to offspring, so that offspring resemble their parents. Traits transmitted this way are called hereditary traits.
  4. Part of the brain responsible for the control of involuntary functions such as breathing, cardiovascular regulation, and swallowing.
  5. Long-term growth of a plant toward or away from a stimulus.

5 True/False questions

  1. bulbThe shaft of the pistil that leads from the stigma down into the ovary.

          

  2. myelin sheathA structure that speeds the movement of action potentials along the axon of a neuron. The sheath is built of Schwann cells, which wrap themselves around the axon of the neuron, leaving small gaps in between known as the nodes of Ranvier.

          

  3. root hairThe part of a plant beneath the soil; responsible for collecting water and minerals from the soil, storing nutrients, and securing the plant to the ground. Can be fibrous or a taproot.

          

  4. fermentationThe second stage of anaerobic respiration, which produces the NAD+ necessary for glycolysis. There are two types of fermentation: alcoholic fermentation and lactic acid fermentation. Yeast engage in alcoholic fermentation, while muscle cells lacking oxygen produce lactic acid.

          

  5. pelagic zoneThe open-ocean zone at the greatest depth in a marine habitat. This zone is divided into a photic (down to 600 feet below the water's surface) and aphotic zone.
