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 rotifer has an arrow pointing to it from the green algae. The green algae is a producer, so the rotifer is a primary consumer.
The bacteria have arrows pointing to them from the copepod and the shiner. Neither the copepod nor the shiner is a producer, so the bacteria are not primary consumers.
The black crappie has arrows pointing to it from the water flea, the rotifer, and the shiner. None of these organisms is a produce, so the black crappie is not a primary consumer.
The copepod has an arrow pointing to it from the golden algae. The golden algae is a producer, so the copepod is a primary consumer. | TheMrguiller/ScienceQA |

Question: [QUESTION]Which of the following contains a vague pronoun reference?
Solution: The first answer choice contains a vague pronoun reference. The pronoun they could refer to the branches or the power lines.
The second answer choice shows a possible correction for the vague pronoun reference. They has been replaced with the branches.
Since the branches had grown over the power lines, Lauren requested a permit to have the branches removed. | TheMrguiller/ScienceQA |

Solution: | 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 B has more mass than each particle in sample A. So, the particles in sample B have a higher average kinetic energy than the particles in sample A.
Because the particles in sample B have the higher average kinetic energy, sample B must have the higher temperature. | TheMrguiller/ScienceQA |
Question: [QUESTION]Is a book a solid, a liquid, or a gas?
Solution: A book is a solid. When you read a book, you bend the spine and turn the pages. But the book still has a shape of its own. | TheMrguiller/ScienceQA |
Question: [QUESTION]Which logical fallacy is used in the text?
Don't ever get a ride from Mariana. Her brother has been driving for only six months, and he's already gotten three speeding tickets.
Solution: The text argues that Mariana must be a reckless driver, because her brother is a reckless driver. However, even though Mariana's brother is reckless, that doesn't necessarily mean that Mariana is, too. This illustrates a type of logical fallacy known as guilt by association. | TheMrguiller/ScienceQA |
Question: [QUESTION]Based on this information, what is Toriel's phenotype for the coat color trait?
Solution: Toriel's genotype for the coat color gene is LL. Toriel's genotype of LL has only L allelles. The L allele is for a black coat. So, Toriel's phenotype for the coat color trait must be a black coat.
To check this answer, consider whether Toriel's alleles are dominant or recessive. The allele for a reddish-brown coat (l) is recessive to the allele for a black coat (L). This means L is a dominant allele, and l is a recessive allele.
Toriel's genotype of LL has two dominant alleles. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, Toriel's phenotype for the coat color trait must be a black coat. | TheMrguiller/ScienceQA |
