	[QUESTION]What is the expected ratio of offspring with climbing growth to offspring with bush growth? Choose the most likely ratio.	[OPTIONS](A) 4:0 (B) 0:4 (C) 2:2 (D) 3:1 (E) 1:3	2:2	To determine how many boxes in the Punnett square represent offspring with climbing growth or bush growth, consider whether each phenotype is the dominant or recessive allele's version of the growth pattern trait. The question tells you that the G allele, which is for climbing growth, is dominant over the g allele, which is for bush growth. Climbing growth is the dominant allele's version of the growth pattern trait. A rose plant with the dominant version of the growth pattern trait must have at least one dominant allele for the growth pattern gene. So, offspring with climbing growth must have the genotype GG or Gg. There are 2 boxes in the Punnett square with the genotype GG or Gg. These boxes are highlighted below. Bush growth is the recessive allele's version of the growth pattern trait. A rose plant with the recessive version of the growth pattern trait must have only recessive alleles for the growth pattern gene. So, offspring with bush growth must have the genotype gg. There are 2 boxes in the Punnett square with the genotype gg. These boxes are highlighted below. So, the expected ratio of offspring with climbing growth to offspring with bush growth is 2:2. This means that, on average, this cross will produce 2 offspring with climbing growth for every 2 offspring with bush growth.	false

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

The magnitude of the magnetic force is smaller in Pair 2.

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. 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.

[QUESTION]Complete the sentence. In this chemical reaction, gasoline is a ().

[OPTIONS](A) reactant (B) product

reactant

Read the underlined text carefully. Look for information about what happens to gasoline in this chemical reaction. Gasoline provides the energy that powers many car engines. In an engine, gasoline and oxygen are mixed together and burned, creating carbon dioxide gas and water vapor. This process releases energy that the engine uses to turn the wheels, making the car move. The underlined text tells you that when gasoline and oxygen combine, carbon dioxide and water are formed. When gasoline and oxygen react, or go through a chemical change, their atoms are rearranged to form carbon dioxide and water. Because gasoline reacts in this chemical reaction, gasoline is a reactant.

[QUESTION]What is the expected ratio of offspring with climbing growth to offspring with bush growth? Choose the most likely ratio.

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

2:2

To determine how many boxes in the Punnett square represent offspring with climbing growth or bush growth, consider whether each phenotype is the dominant or recessive allele's version of the growth pattern trait. The question tells you that the G allele, which is for climbing growth, is dominant over the g allele, which is for bush growth. Climbing growth is the dominant allele's version of the growth pattern trait. A rose plant with the dominant version of the growth pattern trait must have at least one dominant allele for the growth pattern gene. So, offspring with climbing growth must have the genotype GG or Gg. There are 2 boxes in the Punnett square with the genotype GG or Gg. These boxes are highlighted below. Bush growth is the recessive allele's version of the growth pattern trait. A rose plant with the recessive version of the growth pattern trait must have only recessive alleles for the growth pattern gene. So, offspring with bush growth must have the genotype gg. There are 2 boxes in the Punnett square with the genotype gg. These boxes are highlighted below. So, the expected ratio of offspring with climbing growth to offspring with bush growth is 2:2. This means that, on average, this cross will produce 2 offspring with climbing growth for every 2 offspring with bush growth.
