5 Matching questions

  1. hydrophilic
  2. phloem
  3. neritic zone
  4. somatic nervous system
  5. endoskeleton
  1. a The medium depth zone of the marine biome. Extends to 600 feet beneath the water's surface and sits on the continental shelf, hundreds of miles from any shore. Algae, crustaceans, and fish inhabit this region.
  2. b Vascular tissue composed of cells that are living at maturity; transports the products of photosynthesis throughout the plant body.
  3. c Having an affinity for water; usually polar molecules. For the SAT II Biology, this is principally important in relation to the phospholipid bilayer.
  4. d One half of the motor system of the peripheral nervous system. Responsible for voluntary, or conscious, movement. Neurons in this system target skeletal muscles and release the neurotransmitter acetylcholine.
  5. e An interior skeleton found in vertebrates made of bone and cartilage.

5 Multiple choice questions

  1. Epidermal plant cells found in pairs surrounding the stomata of leaves. By increasing or decreasing their size, guard cells regulate gas exchange by opening and closing individual stoma.
  2. The maximum number of individuals in a population that can be sustained in a given environment. As populations become increasingly concentrated, competition for food and space, predation, and disease all determine carrying capacity.
  3. Structures that create movement in an organism by contracting under a stimulus from a neuron. There are three types of muscle: skeletal, which is responsible for voluntary movement; smooth, which is responsible for involuntary movement; and cardiac, which makes up the heart.
  4. An organelle often found in protozoa that pumps excess water out of the cell to keep the cell from bursting in a hypotonic environment (like freshwater).
  5. The center of the central nervous system. The brain coordinates the processes of the body. It is composed of various distinct regions, all of which have different functions, including the cerebrum, cerebellum, medulla oblongata, and hypothalamus.

5 True/False questions

  1. kingdomConnective tissue between bones and muscles.


  2. speciationThe development of a species through evolution. A species forms when its members become reproductively isolated from all other organisms. Speciation can occur through geographic separation that eliminates gene flow or through adaptive radiation.


  3. aphotic zoneLiterally, zone without light. The aphotic zone is part of the marine pelagic zone and begins 600 feet below the surface of the ocean. Only chemosynthetic organisms, scavengers, and predators are able to survive in this habitat.


  4. hydrolysisHaving an affinity for water; usually polar molecules. For the SAT II Biology, this is principally important in relation to the phospholipid bilayer.


  5. electron transport chainThe process by which a plant loses water to its environment through evaporation.
