Passage 1
1) Sedimentation, the process of suspended particles settling, has also been suggested as a cause of coral bleaching. Which scientist would most likely agree with this cause?
C. Scientist 3-sediment would block the light from reaching the algae and coral
What was the temperature of the propanol after 20 minutes of heating during experiment 3?
d) 65 c
14) in experiment 2, what additional change could be tested for its effect on catalase activity?
A) addition of sugar. Look for an answer choice that was not already in table 2
20) In experiment 1, what force would be measured if a wood block with a mass of 0.6kg was pulled across sand paper B?
c) 4.1N focus only on sandpaper B, and don't be distracted all the blocks are wood.
26) The mass of planet 3 is approximately ______ the mass of planet 4?
A) 4 times look for the 2 masses and divide the smaller into the larger.
3) How could the relationship between coral and algae be described?
A) mutualistic: in the introduction it explains that both benefit.
9) In experment 1, as the total elapsed time increase, the temperature of the metals:
H) increased, then decreased
15) Why were the test tubes in the water bath for 10 minutes?
h) the hydrogen peroxide only begins to decompose after 10 minutes.
You have to read the text to get this one. then read the choices and ask yourself is this possible?
21) based on the results of experiment 1, which type of sandpaper was used in experiment 2?
F) A look for the same force with a 0.4 kg mass as the wood in experiment 2.
27) According to figure 1, what two planets would most likely contain craters?
G) Planet 3 and planet 4 it states that planets that come closest to the asteroid field whose signs of craters. Look at orbits not just which two appear closest in the picture.
4)How does the view of scientist 2 differ from both 1 and 3?
F) describes direct damage as well as bleaching
10.vBased on Experiment 1, what would the temperature of the iron be after 80 seconds?
B) 27.6 focus on the iron find the temp before and after 80 seconds.
16) Based on Experiment 2, how much time is needed for enough oxygen to be produced by the yeast to make the filter paper bouyant in acid conditions?
b) 30 seconds Find the data for acid. the one that is most similar to the data listed is the correct choice.
22) Which sandpaper and block combination would have the least friction?
c) glass and sandpaper c. look for the materials that had the lowest amount of force
28) If Mars were in system 273, where would its orbit most likely be located in relation to the other planets?
C) between planets 3 and 4 The further the planet the lower the mean temperature. Find where Mars would fit with the other temperatures.
6) All three scientists agree that coral bleaching is caused by...
J) chemical pollution (in the introduction)
11. The experiment design of experiment 2 differs from experiment 1 in that in experiment 1:
g) The mass of the metal was constant in test.
17) Which graph best represents the results of experiment 3?
g) as time went on the temperature dropped
23) A fifth type of sandpaper was tested. based on the results of experiment 1. which correctly lists the sandpaper in order of increasing friction?
J) C A B E D label a mark on the graph where the 5th sandpaper would fit and then order the letters from lowest to highest friction
29) Planet 2 and planet 4 have similar diameters, but the surface gravity is quite different. What is a possible explanation?
According to scientist 3, it can be assumed that..
f) coral live in shallow clear water
12) In experiment 2 why was styrofoam used as the container for the experiment?
c) it insulates. (you just need to know that styrofoam is an insulator from every day knowledge)
19) Which of the following conclusions are supported by the results of experiment 1?
J) Cooked tissues do not contain as much catalase as raw tissues. Use the process of elimination for to find the correct answer.
24) According to experiment1, if the mass of a block is doubled, the force of friction would.....
a) double look at any of the lines to answer the question.
30) A 5th planet was discovered . Based on the info, where would the planet be located?
B) beyond planet 4, because the mean temperature is lower than planet 4.
