	[QUESTION]What is the expected ratio of offspring with dumbo ears to offspring with normal ears? Choose the most likely ratio.	[OPTIONS](A) 3:1 (B) 0:4 (C) 2:2 (D) 4:0 (E) 1:3	0:4	To determine how many boxes in the Punnett square represent offspring with dumbo ears or normal ears, consider whether each phenotype is the dominant or recessive allele's version of the ear type trait. The question tells you that the E allele, which is for normal ears, is dominant over the e allele, which is for dumbo ears. Dumbo ears is the recessive allele's version of the ear type trait. A rat with the recessive version of the ear type trait must have only recessive alleles for the ear type gene. So, offspring with dumbo ears must have the genotype ee. There are 0 boxes in the Punnett square with the genotype ee. Normal ears is the dominant allele's version of the ear type trait. A rat with the dominant version of the ear type trait must have at least one dominant allele for the ear type gene. So, offspring with normal ears must have the genotype EE or Ee. All 4 boxes in the Punnett square have the genotype EE or Ee. So, the expected ratio of offspring with dumbo ears to offspring with normal ears is 0:4. This means that, based on the Punnett square, this cross will never produce offspring with dumbo ears. Instead, this cross is expected to always produce offspring with normal ears.	false

A symbol contains either one capital letter or a capital letter followed by one or two lowercase letters. The chemical formula for platinum is Pt. This formula contains one symbol: Pt. So, the formula tells you that platinum is made of one chemical element. Substances made of only one chemical element are elementary substances. So, platinum is an elementary substance.

[QUESTION]Which logical fallacy is used in the text? Since Laura Ellis became vice president of the parent-teacher association, student performance has declined and teacher morale is down. We on the school board believe that Ellis bears sole responsibility for the downtrend.

[OPTIONS](A) red herring: the use of a completely unrelated topic or idea (B) false causation: the assumption that because two things happened together, one caused the other

false causation: the assumption that because two things happened together, one caused the other

The text argues that Laura Ellis is responsible for the decline in student performance and teacher morale. However, even though things declined after Ellis became vice president of the parent-teacher association, that doesn't necessarily mean that she caused the downturn. This illustrates a type of logical fallacy known as false causation.

[QUESTION]Which logical fallacy is used in the text? The number of pirates in existence decreased as the global average temperature rose. Therefore, we can conclude that hotter weather reduces piracy.

[OPTIONS](A) false causation: the assumption that because two things happened together, one caused the other (B) slippery slope fallacy: the false assumption that a small first step will lead to extreme consequences (C) guilt by association: a negative association intended to discredit someone or something

false causation: the assumption that because two things happened together, one caused the other

The text argues that an increase in the global average temperature causes less piracy. However, that's not necessarily true. The fact that piracy decreased as global average temperature increased does not mean that hotter weather reduces piracy. This illustrates a type of logical fallacy known as false causation.

[QUESTION]What is the expected ratio of offspring with dumbo ears to offspring with normal ears? Choose the most likely ratio.

[OPTIONS](A) 3:1 (B) 0:4 (C) 2:2 (D) 4:0 (E) 1:3

0:4

To determine how many boxes in the Punnett square represent offspring with dumbo ears or normal ears, consider whether each phenotype is the dominant or recessive allele's version of the ear type trait. The question tells you that the E allele, which is for normal ears, is dominant over the e allele, which is for dumbo ears. Dumbo ears is the recessive allele's version of the ear type trait. A rat with the recessive version of the ear type trait must have only recessive alleles for the ear type gene. So, offspring with dumbo ears must have the genotype ee. There are 0 boxes in the Punnett square with the genotype ee. Normal ears is the dominant allele's version of the ear type trait. A rat with the dominant version of the ear type trait must have at least one dominant allele for the ear type gene. So, offspring with normal ears must have the genotype EE or Ee. All 4 boxes in the Punnett square have the genotype EE or Ee. So, the expected ratio of offspring with dumbo ears to offspring with normal ears is 0:4. This means that, based on the Punnett square, this cross will never produce offspring with dumbo ears. Instead, this cross is expected to always produce offspring with normal ears.

a ship that moved 145kilometers west in 10hours

Look at the distance each ship moved and the time it took to move that distance. The direction each ship moved does not affect its speed. Notice that each ship moved for 10 hours. The ship that moved 145 kilometers moved the shortest distance in that time. So, that ship must have moved at the lowest speed.

[QUESTION]Think about the magnetic force between the magnets in each pair. Which of the following statements is true?

[OPTIONS](A) The magnitude of the magnetic force is greater in Pair 1. (B) The magnitude of the magnetic force is greater in Pair 2. (C) The magnitude of the magnetic force is the same in both pairs.

The magnitude of the magnetic force is greater in Pair 1.

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.
