Think about the magnetic force between the magnets in each pair. Which of the following statements is true?
[ "The magnitude of the magnetic force is the same in both pairs.", "The magnitude of the magnetic force is smaller in Pair 2.", "The magnitude of the magnetic force is smaller in Pair 1." ]
B
Distance affects the magnitude of the magnetic force. When there is a greater distance between magnets, the magnitude of the magnetic force between them is smaller. There is a greater distance between the magnets in Pair 2 than in Pair 1. So, the magnitude of the magnetic force is smaller in Pair 2 than in Pair 1.

[ "The magnitude of the magnetic force is smaller in Pair 2.", "The magnitude of the magnetic force is the same in both pairs.", "The magnitude of the magnetic force is smaller in Pair 1." ]
C
The magnets in Pair 2 attract. The magnets in Pair 1 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. Distance affects the magnitude of the magnetic force. When there is a greater distance between magnets, the magnitude of the magnetic force between them is smaller. There is a greater distance between the magnets in Pair 1 than in Pair 2. So, the magnitude of the magnetic force is smaller in Pair 1 than in Pair 2.

Based on this information, what is this trout's phenotype for the body color trait?
[ "a greenish-brown body", "a blue body" ]
A
You need to determine the rainbow trout's phenotype for the body color trait. First, consider the alleles in the trout's genotype for the body color gene. Then, decide whether these alleles are dominant or recessive. The allele for a blue body (b) is recessive to the allele for a greenish-brown body (B). This means B is a dominant allele, and b is a recessive allele. The rainbow trout's genotype of Bb 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, the rainbow trout's phenotype for the body color trait must be a greenish-brown body.

What is the expected ratio of offspring with a tall stem to offspring with a short stem? Choose the most likely ratio.
[ "4:0", "1:3", "2:2", "3:1", "0:4" ]
A
To determine how many boxes in the Punnett square represent offspring with a tall stem or a short stem, consider whether each phenotype is the dominant or recessive allele's version of the stem height trait. The question tells you that the h allele, which is for a short stem, is recessive to the H allele, which is for a tall stem. A tall stem is the dominant allele's version of the stem height trait. A pea plant with the dominant version of the stem height trait must have at least one dominant allele for the stem height gene. So, offspring with a tall stem must have the genotype HH or Hh. All 4 boxes in the Punnett square have the genotype HH or Hh. A short stem is the recessive allele's version of the stem height trait. A pea plant with the recessive version of the stem height trait must have only recessive alleles for the stem height gene. So, offspring with a short stem must have the genotype hh. There are 0 boxes in the Punnett square with the genotype hh. So, the expected ratio of offspring with a tall stem to offspring with a short stem is 4:0. This means that, based on the Punnett square, this cross will always produce offspring with a tall stem. This cross is expected to never produce offspring with a short stem.

The difference between the number of boys and girls in a tree planting event is 400. If there are 600 boys at the event, and the number of girls is more than the number of boys, what's 60% of the total number of boys and girls at the event?
null
960
If there are 600 boys at the event, and the difference between boys and girls is 400, there are 600+400=<<600+400=1000>>1000 girls. The total number of boys and girls at the event is 1000+600=<<1000+600=1600>>1600 60% of the total number of boys and girls at the event is 60/100*1600=<<60/100*1600=960>>960 #### 960

Which solution has a higher concentration of green particles?
[ "Solution B", "neither; their concentrations are the same", "Solution A" ]
A
In Solution A and Solution B, the green particles represent the solute. To figure out which solution has a higher concentration of green particles, look at both the number of green particles and the volume of the solvent in each container. Use the concentration formula to find the number of green particles per milliliter. Solution B has more green particles per milliliter. So, Solution B has a higher concentration of green particles.

Think about the magnetic force between the magnets in each pair. Which of the following statements is true?
[ "The strength of the magnetic force is the same in both pairs.", "The magnetic force is stronger in Pair 1.", "The magnetic force is stronger in Pair 2." ]
C
Distance affects the strength of the magnetic force. When magnets are closer together, the magnetic force between them is stronger. The magnets in Pair 2 are closer together than the magnets in Pair 1. So, the magnetic force is stronger in Pair 2 than in Pair 1.
