Question 1 of 40
1. Question
1 pointsA solar eclipse occurs when the moon blocks our view of the sun. Select the diagram that best represents the position of the sun, the Earth, and the moon during a solar eclipse, as well as the correct orbits
Correct
Incorrect
This diagram corresponds to the correct arrangement of Earth, moon, and the sun during a solar eclipse. The moon is located between the Earth and the sun, blocking the Earth’s view of the sun. It also corresponds to the correct orbits, with the moon orbiting around the Earth, and the Earth around the sun. Choice b is wrong because it shows the sun orbiting around the Earth, and the moon around the sun. Choice c is wrong because the Earth, moon, and sun are not aligned as they should be during an eclipse, and the moon is not orbiting around the Earth. Choice d shows correct orbits, but the moon is not blocking the sun from the Earth’s view. In fact, choice d corresponds to a lunar eclipse. Choice e is wrong because it shows the Earth and the sun orbiting around the moon.

Question 7 of 40
7. Question
1 pointsQuestions 7 and 8 are based on the following passage
According to scientists, the sun has existed for 4.6 billion years. The sun produces energy by a nuclear conversion of hydrogen into helium. When hydrogen runs out, according to this theory, the sun will expand, engulfing Earth and other planets. Not to worry—the expansion will not affect us, since the sun has enough hydrogen for another 4.6 billion years. When it expands, the sun will become what is called a red giant star. In another 500 million years, the sun will shrink to the current size of the Earth and will be called a white dwarf, cooling down for several billion years.
According to the passage, the sun will eventually
Correct
Incorrect
The passage states that the sun will first expand (not shrink—choices b, c, and e) when it runs out of hydrogen (not helium—choice d), and then 500 million years later, it will shrink.

Question 9 of 40
9. Question
1 pointsWebbed feet enable ducks to swim better by
Correct
Incorrect
Webbed feet enable ducks to swim better by increasing the surface area on their feet. In swimming, being hydrodynamic, not aerodynamic, is important (choice a). Stuck particles between a duck’s toes, choice c, would most likely not be a frequent problem. Webbed feet would not affect the duck’s density, choice d, by much. The rate of heat loss, choice e, maybe slightly higher because of the larger surface area, but heat loss is not essential for swimming.

Question 10 of 40
10. Question
1 pointsDetermine how much water is in the graduated cylinder drawn below by reading the bottom of the meniscus (surface of water).
Correct
Incorrect
The top division on the graduated cylinder is the 10 ml mark. There are 10 divisions, so each one is 1 ml. The bottom of the meniscus is between 7 ml and 8 ml, so 7.5 ml is the best answer.

Question 11 of 40
11. Question
1 pointsIn addition to magnifying the image of an object, a microscope inverts the image left to right. The image of the object observed through the microscope is also upside down. Looking through the eyepiece, you would therefore see the upside-down mirror image of the object under the microscope lens. What would the object below look like if observed through the microscope?
Correct
Incorrect
This is what the object looks like when it is inverted left to right (mirror image).When the object is flipped upside down, there is no change in its appearance.

-
Question 16 of 40
16. Question
1 points. In 1969, two scientists devised an experiment to test a hypothesis that the number of species in an ecosystem depends on the area of the ecosystem. They counted all the arthropod species on a few very tiny islands. They then exterminated all the arthropods (mostly insects) with a pesticide. Over six months, they monitored the gradual repopulation of the island and noticed that by the end of the observation period, each island had almost the same number of species as it had before pesticide was used. However, the kinds of species that arrived often differed from the
species that were on the island prior to pesticide use. Here is a chart that illustrates the results.Based on the chart, which trophic level suffered the greatest net loss (number of species) in diversity?
Correct
Incorrect
The number of species lost was greatest in ants.
-
Question 17 of 40
17. Question
1 pointsQuestions 17 and 18 are based on the following passage.
A science student hypothesized that the rate of evaporation of water depends on the shape of the container the water is placed in. She decided to measure the amount of water evaporated when 300 ml of water in five different containers was heated from room temperature to 90° C on preheated hot plates. She used five cylindrical 500-milliliter glass containers, each having the same wall thickness but a different base radius and height. In other words, some containers were narrow and tall, others were wide and shallow. The following table lists the dimensions of the containers and the amount of water initially present.
She placed each container, containing the same amount of water, on a hot plate, and placed a thermometer in each to monitor the temperature. She noticed that the temperature was increasing faster in the containers with a larger radius. After some time, the temperature in the 10-cm radius container reached the set 90° C. Following container 5, the water in containers 4, 3, 2, and 1, in that order, reached the set temperature. The student checked the volume of the water in each container and found that it was lower than 300 ml. She also found that the decrease in volume was highest in the container with the largest radius. In container 1, volume decrease was barely detectable.
What can the student conclude from the data?
Correct
Incorrect
“She also found that the decrease in volume was highest in the container with the largest radius. In container 1, volume decrease was barely detectable.” Choice d and e are false because the container with the larger radius reached the set temperature faster.

Question 18 of 40
18. Question
1 pointsQuestions 17 and 18 are based on the following passage.
A science student hypothesized that the rate of evaporation of water depends on the shape of the container the water is placed in. She decided to measure the amount of water evaporated when 300 ml of water in five different containers was heated from room temperature to 90° C on preheated hot plates. She used five cylindrical 500-milliliter glass containers, each having the same wall thickness but a different base radius and height. In other words, some containers were narrow and tall, others were wide and shallow. The following table lists the dimensions of the containers and the amount of water initially present.
She placed each container, containing the same amount of water, on a hot plate, and placed a thermometer in each to monitor the temperature. She noticed that the temperature was increasing faster in the containers with a larger radius. After some time, the temperature in the 10-cm radius container reached the set 90° C. Following container 5, the water in containers 4, 3, 2, and 1, in that order, reached the set temperature. The student checked the volume of the water in each container and found that it was lower than 300 ml. She also found that the decrease in volume was highest in the container with the largest radius. In container 1, volume decrease was barely detectable.
Which two statements are valid objections to the experimental setup?
I. All the containers were filled with the same amount of water.
II. A different hot plate was used to heat water in different containers.
III. Water in different containers was heated for different amounts of time.
IV. The containers were not filled completelyCorrect
Incorrect
There is nothing wrong with I and IV. Using different hot plates can have an effect because some hot plates may be heating more efficiently than others. Heating water in all the containers for the same amount of time, rather than up to a fixed temperature, would be better because the rate of evaporation is the amount of water lost per unit of time. By using different times, the student is changing an important variable.

Question 19 of 40
19. Question
1 pointsThe following graph shows how the concentration (amount per unit volume) changes with
time. What information can be obtained from the data?Correct
Incorrect
Choice a is wrong because initially, the concentration decreases. There is no information about the product on the chart, so choice b is incorrect. Choice d is wrong because at 500 seconds, the concentration is not zero. Choice e is wrong because at 300 seconds, the concentration is lower than at other times, at the start of the experiment.

Question 20 of 40
20. Question
1 pointsQuestions 20 and 21 are based on the following passage
Is Pluto a Planet?
Based on perturbations in Neptune’s orbit, the search for a ninth planet was conducted and Pluto was discovered in 1930. Pluto orbits the sun just like the other eight planets, and it has a moon, Charon, and a stable orbit. Based on its distance from the sun, Pluto should be grouped with the planets known as gas giants. In addition, Pluto, like the planet Mercury, has little or no atmosphere. Pluto is definitely not a comet because it does not have a tail like a comet when it is near the sun. Pluto is also not an asteroid, although its density is closer to an asteroid than to any of the other planets. Pluto is a planet because it has been classified as one for more than sixty years since its discovery.Which argument supporting the classification of Pluto as a planet is the weakest?
Correct
Incorrect
This is the weakest argument because it is justified with authority, tradition, and past belief, rather than scientific facts. People have been wrong in the past, and noting that something has been done a certain way for years does not mean that there are no better ways, and it is not a convincing scientific argument.

Pluto is also not an asteroid, although its density is closer to an asteroid than to any of the other planets. Pluto is a planet because it has been classified as one for more than sixty years since its discovery.Which one of the following statements is NOT backed with an explanation?
Correct
Incorrect
The passage states that Pluto’s density is closer to an asteroid’s than to any of the planets’. This would lead the reader to think that Pluto, based on its density, maybe an asteroid. But the passage states that this is not the case and does not give arguments to support the statement. The statements in all other choices are supported by facts.

Question 27 of 40
27. Question
1 pointsQuestions 27 and 28 are based on the following passage
Farm animals can carry salmonella, a kind of bacteria that can cause severe food poisoning. However, animals fed antibiotics can carry especially deadly strains of salmonella. In Minnesota in 1983, 11 people were hospitalized with salmonella poisoning. This number itself was not striking at all. Forty thousand Americans are hospitalized with salmonella poisoning every year. What was striking about the cases in Minnesota was that each patient had severe symptoms and all the patients were infected with the same, rare strain of salmonella, resistant to several common antibiotics. A young scientist, Scott Holmberg, noted that eight patients were taking the same antibiotics for sore throats. He ruled out the possibility that the antibiotics themselves were infected with the bacteria because three of the patients were not taking antibiotics at all. He later showed that the people were infected with salmonella prior to taking the antibiotics, but that the antibiotics triggered the onset of salmonella poisoning. He postulated that salmonella suddenly flourished when the patients took antibiotics because the antibiotics killed off all other competing bacteria. He was also able to trace the antibiotic resistant salmonella to the beef that was imported to Minnesota from a farm in South Dakota, at which cattle were routinely fed antibiotics and at which one calf died of the same strain of salmonella.
As a result of this finding, the Food and Drug Administration should
Correct
Incorrect
Choice a is already being done, and since the antibiotics weren’t directly making people ill (choice e), these measures wouldn’t be necessary. There is nothing that indicates that all meat from South Dakota has salmonella or that meat from everywhere else is always healthy, so choice b would not be necessary. Choice d is wrong because antibiotics are not resistant to salmonella; some salmonella is resistant to antibiotics.

Question 37 of 40
37. Question
1 pointsQuestions 37 and 38 are based on the following passage.
Radiation from radioisotopes can be used to kill cancer cells. Chemist Marie Curie received two Nobel Prizes for her work with radioisotopes. Her work led to the discovery of the neutron and synthesis of artificial radioactive elements. She died of leukemia at 67, caused by extensive exposure to radiation. Curie never believed that radium and other materials she worked with were a health hazard. In World War I, glowing radium was used on watch dials to help soldiers read their watches in the dark and to synchronize their attacks. Unfortunately, women who worked in factories were drawing their radium stained brushes to fine points by putting them between their lips. As a result, their teeth would glow in the dark. But this was an amusement for children more than a cause of worry. About ten years later, the women developed cancer in their jaws and mouths and had problems making blood cells. This exposed the dangers of radiation.
Based on the information in the passage, which statement about radioisotopes is false?
Correct
Incorrect
There was no mention of Einstein in the passage. All the other statements were made.

Question 39 of 40
39. Question
1 pointsQuestions 39 and 40 are based on the following passage.
In the past, people thought that the Earth was flat and that a ship that sailed too far would fall off the edge of the world. The Earth appears flat because the Earth is too large for humans on Earth to see its curvature. Several events helped shed the misconceptions. For one, during a lunar eclipse, the Earth is positioned between the sun and the moon. It eclipses the moon by casting a shadow on it. The shadow the Earth casts is round. When Magellan circumnavigated the Earth, he proved that one could not fall off the edge of the Earth, because the Earth was round and had no edges. Finally, space missions provided us with images of our round Earth from far away and showed us how beautiful our planet looks, even from a distance.
In the passage, what was cited as proof that the Earth is round?
I. Earth casts a round shadow on the moon during a lunar eclipse.
II. Earth revolves around the sun.
III. Magellan circumnavigated the Earth.
IV. images from spaceCorrect
Incorrect
Statements I, III, and IV were made in the passage. Statement II is true, but it does not prove that the Earth is round and was not discussed in the passage.
