Question: [QUESTION]What do these two changes have in common?
a piece of pear turning brown
salt and vinegar removing tarnish from a penny
Solution: Step 1: Think about each change.
A piece of a pear turning brown is a chemical change. The substances in the pear react with oxygen in the air and turn into a different type of matter.
If you scrape off the brown part of the pear, the inside will still be white. The inside hasn't touched the air. So the chemical change hasn't happened to that part of the pear.
Salt and vinegar removing tarnish from a penny is a chemical change. The salt and vinegar change the tarnish into a different type of matter that can be easily wiped away. This makes the penny look shiny again.
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.

In the Bible, Job complains to God about his hardships, saying that both strangers and those he loves have turned against him. He says, "My bone cleaveth to my skin and to my flesh, and I am escaped with the skin of my teeth." Scholars have long debated the exact meaning of the phrase, but many claim that Job is saying that he narrowly escaped death.
The allusion by the skin of his teeth means just barely. | TheMrguiller/ScienceQA |
Question: [QUESTION]What is the expected ratio of offspring with smooth fruit to offspring with bumpy fruit? Choose the most likely ratio.
Solution: To determine how many boxes in the Punnett square represent offspring with smooth fruit or bumpy fruit, consider whether each phenotype is the dominant or recessive allele's version of the fruit texture trait. The question tells you that the f allele, which is for smooth fruit, is recessive to the F allele, which is for bumpy fruit.
Smooth fruit is the recessive allele's version of the fruit texture trait. A cucumber plant with the recessive version of the fruit texture trait must have only recessive alleles for the fruit texture gene. So, offspring with smooth fruit must have the genotype ff.
There are 0 boxes in the Punnett square with the genotype ff.
Bumpy fruit is the dominant allele's version of the fruit texture trait. A cucumber plant with the dominant version of the fruit texture trait must have at least one dominant allele for the fruit texture gene. So, offspring with bumpy fruit must have the genotype FF or Ff.
All 4 boxes in the Punnett square have the genotype FF or Ff.
So, the expected ratio of offspring with smooth fruit to offspring with bumpy fruit is 0:4. This means that, based on the Punnett square, this cross will never produce offspring with smooth fruit. Instead, this cross is expected to always produce offspring with bumpy fruit. | TheMrguiller/ScienceQA |

Question: [QUESTION]Which property do these three objects have in common?
Solution: Look at each object.
For each object, decide if it has that property.
A translucent object lets light through. But you cannot see clearly through a translucent object. All three objects are translucent.
A rough object feels scratchy when you touch it. None of the objects are rough.
A hard object does not change shape when pressed or squeezed. None of the objects are hard.
The property that all three objects have in common is translucent. | TheMrguiller/ScienceQA |

Question: [QUESTION]Which of the following organisms is the primary consumer in this food web?
Solution: Primary consumers eat producers. So, in a food web, primary consumers have arrows pointing to them from producers.
The barren-ground caribou has an arrow pointing to it from the lichen. The lichen is a producer, so the barren-ground caribou is a primary consumer.
The brown lemming has arrows pointing to it from the bilberry and the bear sedge. The bilberry and the bear sedge are producers, so the brown lemming is a primary consumer.
The snowy owl has an arrow pointing to it from the short-tailed weasel. The short-tailed weasel is not a producer, so the snowy owl is not a primary consumer.
The bear sedge does not have any arrows pointing to it. So, the bear sedge is not a primary consumer. | TheMrguiller/ScienceQA |
Question: [QUESTION]Which solution has a higher concentration of pink particles?
Solution: In Solution A and Solution B, the pink particles represent the solute. To figure out which solution has a higher concentration of pink particles, look at both the number of pink particles and the volume of the solvent in each container.
Use the concentration formula to find the number of pink particles per milliliter.
Solution A and Solution B have the same number of pink particles per milliliter. So, their concentrations are the same. | TheMrguiller/ScienceQA |
Question: [QUESTION]Is the following statement about our solar system true or false?
The volume of Earth is more than ten times the volume of Mercury.
Solution: To determine if this statement is true, calculate the value of ten times the volume of Mercury.
Then compare the result to the volume of Earth. The volume of Earth is 1.08 x 10^12 km^3, which is greater than 6.08 x 10^11 km^3. So, the volume of Earth is more than ten times the volume of Mercury. | TheMrguiller/ScienceQA |

Question: [QUESTION]Compare the average kinetic energies of the particles in each sample. Which sample has the higher temperature?
Solution: The particles in both samples have the same average speed, but each particle in sample A has more mass than each particle in sample B. So, the particles in sample A have a higher average kinetic energy than the particles in sample B.
Because the particles in sample A have the higher average kinetic energy, sample A must have the higher temperature. | TheMrguiller/ScienceQA |
