Question 4

During a demonstration, a teacher placed 20 mL of water, 10 mL of isopropyl alcohol (IPA), and 1 drop of blue food coloring into a test tube, capped the test tube, and inverted it 6 times. Next, she added 7 g of ammonium sulfate (AS), an ionic solid, to the test tube, capped the test tube, and vigorously shook it for 10 sec. Then, over the 15 sec period immediately following the shaking, the mix- ture in the test tube completely separated into 2 distinct liquid layers (see figure).The teacher asked each of 4 students to provide an explanation for what occurred in the test tube over the 15 sec period.Student 1Over the 15 sec, the mixture separated into 2 layers because IPA is denser than water. The water layer was on top, and the IPA layer was on the bottom. The AS dissolved in the IPA only, because AS breaks apart into neutral molecules when dissolved in IPA. Blue food colouring is polar, so it dissolves in the water only.Student 2Over the 15 sec, the mixture separated into 2 layers because water is denser than IPA. The IPA layer was on top, and the water layer was on the bottom. The AS dis- solved in the water only, because AS breaks apart into neutral molecules when dissolved in water. Blue food colouring is polar, so it dissolves in the IPA only.Based on the figure, 5 see after the shaking, would the contents of the test tube have been better classified as a heterogeneous mixture or a homogeneous mixture?

Accepted Answer

Heterogeneous, because the contents of the test tube varied in composition from one region to another.

Answer

Homogeneous, because the contents of the test tube varied in composition from one region to another.

Answer

Heterogeneous, because the contents of the test tube were uniform in composition throughout.

Answer

Homogeneous, because the contents of the test tube were uniform in composition throughout.

Question 5

Question 12

The figure below is a pedigree that shows the inheritance of a trait, Trait G, in a family. The presence of Trait G in an individual is determined entirely by Gene G. Gene G has 2 alleles: G, which is dominant, and g, which is recessive.Each individual represented in the pedigree was assigned a number (shown below the symbol for the individual) for reference. Scientists determined that the Gene G genotype of Individual 20 is Gg and that the Gene G genotype of Individual 21 is gg. Based on this information, the scientists concluded that Trait G is a dominant trait.Based on the figure, the 2 individuals in which of the following pairs most likely have the greatest genetic similarity across their genomes?

Accepted Answer

Individual 12 and Individual 13

Answer

Individual 3 and Individual 4

Answer

Individual 16 and Individual 24

Answer

Individual 18 and Individual 21

Question 13

Passage IThe figure below is a pedigree that shows the inheritance of a trait, Trait G, in a family. The presence of Trait G in an individual is determined entirely by Gene G. Gene G has 2 alleles: G, which is dominant, and g, which is recessive.Each individual represented in the pedigree was assigned a number (shown below the symbol for the individual) for reference. Scientists determined that the Gene G genotype of Individual 20 is gg and that the Gene G genotype of Individual 21 is Gg. Based on this information, the scientists concluded that Trait G is a recessive trait.Suppose that Individual 23 and Individual 24 have 4 biological children.
