Question: [QUESTION]What do these two changes have in common?
a piece of avocado turning brown
boiling sugar to make caramel
Solution: Step 1: Think about each change.
A piece of avocado turning brown is a chemical change. The avocado reacts with oxygen in the air to form a different type of matter.
If you scrape off the brown part of the avocado, the inside will still be green. The inside hasn't touched the air. So the chemical change hasn't happened to that part of the avocado.
Boiling sugar to make caramel is a chemical change. The heat causes the sugar to change into a different type of matter. Unlike sugar, the new matter is brown and sticky.
Step 2: Look at each answer choice.
Both are only physical changes.
Both changes are chemical changes. They are not physical changes.
Both are chemical changes.
Both changes are chemical changes. The type of matter before and after each change is different.

Question: [QUESTION]Think about the magnetic force between the magnets in each pair. Which of the following statements is true?
Solution: The magnets in Pair 1 attract. The magnets in Pair 2 repel. But whether the magnets attract or repel affects only the direction of the magnetic force. It does not affect the magnitude of the magnetic force.
Magnet sizes affect the magnitude of the magnetic force. Imagine magnets that are the same shape and made of the same material. The larger the magnets, the greater the magnitude of the magnetic force between them.
Magnet A is the same size in both pairs. But Magnet B is larger in Pair 1 than in Pair 2. So, the magnitude of the magnetic force is greater in Pair 1 than in Pair 2. | TheMrguiller/ScienceQA |

The Davidsons see their relatives whenever they visit Florida.
The second answer choice shows a possible correction for the vague pronoun reference. The text has been rewritten so that the meaning is clear.
Whenever the Davidsons visit Florida, they see their relatives. | TheMrguiller/ScienceQA |
Question: [QUESTION]Select the organism in the same genus as the bobcat.
Solution: A bobcat's scientific name is Lynx rufus. The first word of its scientific name is Lynx.
Halichoeres hortulanus is in the genus Halichoeres. The first word of its scientific name is Halichoeres. So, Halichoeres hortulanus and Lynx rufus are not in the same genus.
Lynx lynx is in the genus Lynx. The first word of its scientific name is Lynx. So, Lynx lynx and Lynx rufus are in the same genus.
Macropus rufus and Lynx rufus are not in the same genus.
These organisms are not in the same genus, but part of their scientific names is the same. Macropus rufus and Lynx rufus have the same species name within their genus, rufus. But the first words of their scientific names are different. Macropus rufus is in the genus Macropus, and Lynx rufus is in the genus Lynx. | TheMrguiller/ScienceQA |
Question: [QUESTION]Which bird's beak is also adapted to crack hard seeds?
Solution: Look at the picture of the bronze mannikin.
The bronze mannikin has a short, thick beak. Its beak is adapted to crack hard seeds. The bronze mannikin uses its short, thick beak to press down on a seed and crack open its hard shell.
Now look at each bird. Figure out which bird has a similar adaptation.
The large ground finch has a short, thick beak. Its beak is adapted to crack hard seeds.
The sword-billed hummingbird has a long, thin beak. Its beak is not adapted to crack hard seeds. The sword-billed hummingbird uses its beak to drink nectar out of long flowers. | TheMrguiller/ScienceQA |
Question: [QUESTION]What is the source of the allusion in the sentence below?
Alana thinks Mr. Cline is a Luddite because he doesn't own a cell phone.
Solution: The source of the allusion Luddite is British history.
In the early nineteenth century, factories were replacing the jobs of craftsmen. Some of these craftsmen banded together to destroy the new machinery; those who did so were called Luddites.
The allusion Luddite means a person opposed to new technology. | TheMrguiller/ScienceQA |
Question: [QUESTION]Based on this information, what is Clyde's phenotype for the coat pattern trait?
Solution: You need to determine Clyde's phenotype for the coat pattern trait. First, consider the alleles in Clyde's genotype for the coat pattern gene. Then, decide whether these alleles are dominant or recessive.
The allele for solid coloring (A) is dominant over the allele for white spots (a). This means A is a dominant allele, and a is a recessive allele.
Clyde's genotype of Aa has one dominant allele and one recessive allele. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, Clyde's phenotype for the coat pattern trait must be solid coloring. | TheMrguiller/ScienceQA |

Solution: This country is Saint Kitts and Nevis. | TheMrguiller/ScienceQA |
Question: [QUESTION]Will these magnets attract or repel each other?
Solution: To predict if these magnets will attract or repel, look at which poles are closest to each other.
The south pole of one magnet is closest to the north pole of the other magnet. Opposite poles attract. So, these magnets will attract each other. | TheMrguiller/ScienceQA |
Question: [QUESTION]Which of these organisms contains matter that was once part of the lichen?
Solution: Use the arrows to follow how matter moves through this food web. For each answer choice, try to find a path of arrows that starts from the lichen.
The only arrow pointing to the snowy owl starts from the short-tailed weasel. The only arrow pointing to the short-tailed weasel starts from the brown lemming. The brown lemming has two arrows pointing to it. These arrows start from the bear sedge and the bilberry. Neither the bear sedge nor the bilberry has any arrows pointing to it. So, in this food web, matter does not move from the lichen to the snowy owl.There is one path matter can take from the lichen to the grizzly bear: lichen->barren-ground caribou->grizzly bear. There are two paths matter can take from the lichen to the mushroom: lichen->barren-ground caribou->mushroom. lichen->barren-ground caribou->grizzly bear->mushroom. brown lemming. The brown lemming has two arrows pointing to it. These arrows start from the bear sedge and the bilberry. Neither the bear sedge nor the bilberry has any arrows pointing to it. So, in this food web, matter does not move from the lichen to the brown lemming.. bilberry. The bilberry does not have any arrows pointing to it. So, in this food web, matter does not move from the lichen to the bilberry.. | TheMrguiller/ScienceQA |

Solution: Look at the legend on the map.
The rest of the Thirteen Colonies were part of New England or the Southern Colonies. | TheMrguiller/ScienceQA |
Question: [QUESTION]Which object has more thermal energy?
Solution: The two bricks have the same mass but different temperatures. Since the 365°F brick is hotter than the 285°F brick, it has more thermal energy. | TheMrguiller/ScienceQA |
Question: [QUESTION]Which of the following could Isabelle and Kayla's test show?
Solution: | TheMrguiller/ScienceQA |
Question: [QUESTION]Think about the magnetic force between the magnets in each pair. Which of the following statements is true?
Solution: Magnet sizes affect the magnitude of the magnetic force. Imagine magnets that are the same shape and made of the same material. The smaller the magnets, the smaller the magnitude of the magnetic force between them.
Magnet A is the same size in both pairs. But Magnet B is smaller in Pair 2 than in Pair 1. So, the magnitude of the magnetic force is smaller in Pair 2 than in Pair 1. | TheMrguiller/ScienceQA |
