  1. Unit #4 Exam Review Quiz Grade: «grade» «subject» Subject: «date» Date:

  2. 1 A gastrovascular cavity is best described as a pit or a sack in which food in inserted to be digested and diffused prior to being ejected back out of the same orifice. Which of the following has the best demonstration of a GVC: A Porifera B Humans C Echinoderms D Cnidarians

  4. 3 Which chemical is predominantly responsible for acid rain: A sulfur dioxide B carbon dioxide C chlorine dioxide D methane gas

  5. 4 The greenhouse effect involves: A energy from the sun being trapped within the atmosphere & warming an area B energy from the sun being trapped within the atmosphere & cooling the area C energy from the sun causing carbon dioxide to turn into a solid D energy from the sun converting halides into noble gases

  6. 5 While you are walking along a beach you suddenly feel a stinging pain in your foot. You look down to see a Man-O’-War (similar to a jellyfish) attached to your stinging foot, and at the same time you notice that the toes on your foot begin to go numb. You were stung by the _________ of the Man-O’-War and it injected a ___________ into your foot. A Tentacle, hemotoxin B Nematocyst, neurotoxin C Nematocyst, hemotoxin D Tentacle, neurotoxin

  7. 6 Cnidarians are polymorphic. Their two different stages are called: A Asexual and hermaphroditic B Asexual and sexual C Polyp and medusa D Polyp and asexual

  8. 7 Amebocytes help digest food and diffuse the nutrients to which of the following types of organisms: A Porifera B Cnidaria C Echinoderms D Choanocytes

  9. 8 Detrivores get their energy from: A Using photosynthesis to create glucose B Consuming living organisms to create ATP C Using chemical, such as heavy metals, to create energy D Consuming dead tissue to create ATP

  10. 9 Which of the following organisms would be best fit to survive within an intertidal zone: A An organism that can grow rapidly & defend itself well when exposed to consistent amount of dissolved oxygen B An organism that can withstand drastic changes in temperature, pH, and pressure C An organism that has a shell to prevent dehydration & limbs strong enough to move itself without the buoyant force of water D An organism that has so few cell layers that it only needs to buoyant force of water to stay suspended within the water column

  11. 10 Which of the following gives a porifera its rigid structure: A ostia B choanocytes C spongin D spicules

  12. 11 Which of the following describe a thermocline that would be found in a lentic body of water: A A gradual decline in the temperature of an ocean that is directly connected to the decline of sunlight within the body of water B A gradual decline in pressure of an ocean that is directly connected to the tides C The warm upper layer of water found in a lake D A zone in a lake where the temperature of the water changes rapidly

  13. 12 All of the following are true about zooxanthellae EXCEPT: A Zooxanthellae are responsible for the color in many coral polyps B Zooxanthellae are responsible for the majority of energy within many coral polyps C Zooxanthellae replication is responsible for coral bleaching D Zooxanthellae are symbiotes that live within many Cnidaria

  14. 13 In an aquarium containing a jellyfish a student knocks over a toxic sample of chlorine indicator. This indicator splashes into the water directly above the jellyfish and the jellyfish begins to move to the opposing side of the aquarium. The receptor most likely responsible for this detection is a(an): A Photoreceptor B Chemoreceptor C Ocelli D Statocyst

  15. 14 Which of the following organisms would be best fit to survive within an intertidal zone: A An organism that can grow rapidly & defend itself well when exposed to consistent amount of dissolved oxygen B An organism that can withstand drastic changes in temperature, pH, and pressure C An organism that has a shell to prevent dehydration & limbs strong enough to move itself without the buoyant force of water D An organism that has so few cell layers that it only needs to buoyant force of water to stay suspended within the water column

  16. 15 You would be able to find a large quantity of phytoplankton in a(n) A Eutrophic Lake B Oligotrophic Lake C 2nd Order Stream D Headwaters

  17. 16 All of the following are representative of radial symmetry, EXCEPT: B A C D

  18. 17 When a cnidarian releases medusa copies off of the top of the organism, this is best demonstrating A Sexual reproduction B Asexual reproduction C Hermaphroditic reproduction D This is a defense mechanism addressing the difficulty of finding a mate

  19. 18 One advantage of a complete digestive system (1-way) over an incomplete digestive system (2-way) is that an organism with a complete system: A Must pause to eject waste through its mouth prior to eating a food source larger than its’ GVC B Can continue to consume food without having to eject that food through the same orifice that it is consuming food C Must input food through multiple orifices while ejecting waste out of similar orifices D An organism can simply diffuse nutrients through the thin tissues surrounding the organism

  20. 19 Porifera are made up of four different cells. Which of the following is NOT one of those cells: A Choanocytes B Amoebocytes C Spongin D Oscullum

  21. 20 When a bacterium is stressed it will form a ________ in an attempt to keep its offspring alive. A Spore B Gemmule C Capsid D Cyst

  22. 21 An example of hermaphroditic reproduction would be: A A Platyhelminthes tearing itself in two on a sharp object and then regenerating into two organisms B A star fish being cut in half by a fisherman and regenerating once tossed back into the water C Two medusas releasing sperm and egg and those gametes intermingling and forming offspring D A Porifera releasing sperm and egg and those gametes intermingling and forming offspring

  23. 22 The number of organisms of one species that live in a specific area defines: A a community B an ecosystem C a population D a biome
