6 Final Jeopardy Famous Scientists

7 Final Jeopardy Neils Bohr Scientist who proposed that electrons move around the nucleus in certain paths

8 $200 Fresh water This is Daphnia’s habitat..

9 $400 A jerky motion Dapnia moves in this way.

10 $600 Algae or bacteria Microorganism eaten by Daphnia.

11 $800 Excellent protection An advantage of having an exoskeleton.

12 $1000 parthenogenesis Asexual reproduction in which eggs hatch without fertilization.

13 $200 somersaults The way that Hydra moves in the water.

14 $400 Enzymes or acids Substance produced by Hydra’s inner layer of cells in the digestive cavity.

15 $600 diffusion This process is used to distribute nutrients throughout the Hydra’s body.

16 $800 They lay eggs (sexually) Hydra reproduce this way in the winter due to the cold temperatures.

17 $1000 Nerve net Part of Hydra that controls movement of muscles.

18 $200 Salt water Jellyfish habitat.

19 $400 water Jellyfish are composed of 95% of this substance.

20 $600 Tentacles or nematocysts Structure used for hunting that Jellyfish have in common with Hydra.

21 $800 Box jellyfish Type of Jellyfish that are extremely deadly.

22 $1000 Low oxygen levels Conditions under which Jellyfish thrive, caused by dumping of chemicals in the ocean.

23 $200 Crustacea Class of organisms with gills, 2 pair of antennae and many appendages.

24 $400 Hollow bodies and tentacles Two characteristics shared by Cnidarians.

25 $600 Arthropoda Daphnia is a member of this phylum.

26 $800 Insecta Organisms in this class are related to Crustaceans but have wings and do not have gills.

27 $1000 They lack freedom of movement/flexibility Disadvantage arthropods have regarding their exoskeletons.

28 $200 Carapace Transparent exoskeleton found in Daphnia

29 $400 Sting cell Type of cell on Hydra that contains a nematocyst.

30 $600 Stimulant Substance that causes the heartbeat to increase.

31 $800 Brood chamber Place where eggs are stored in Daphnia.

32 $1000 Gills Structures used for gas exchange, found in Daphnia and other Crustaceans.

33 $200 movement This is the function of Daphnia’s second antenna.

34 $400 Portugese man-of-war Type of jellyfish that gives severe stings to humans, but is not usually lethal.

35 $600 budding Method of reproduction found in Hydra and yeast.

36 $800 bristles Structure found on legs of Daphnia, used to catch food particles.

37 $1000 Alcohol (or depressant) Example of a substance that slows the heartbeat of organisms, including Daphnia.

38 $ sodium

39 $800 Halogens

40 $ He

41 $ In order for a compound to be stable, the oxidation numbers must add up to this number

42 $2000 Non metals Elements that tend to gain electrons easily are called

51 $1600 quarks Protons and neutrons are actually composed of these smaller particles

52 $2000 neutrons Carbon-14 is different from carbon-12 because it has 2 more of these particles in its nucleus

53 $400 families The vertical columns of the periodic table are called groups or

58 $400 Non metals All of the noble gases are (metals, non metals)

59 $800 argon An element in this group that is used in light bulbs

60 $ Group number

61 $ This group is unreactive because most of the elements have this number of valence electrons

62 $2000 inert Another name for the noble gases

63 $400 valence An atom’s chemical reactivity is determined by its number of these kind of electrons
