A mycologist performed an experiment to determine the effect of methanol on the mold Neurospora crassa.
1,500 Neurospora spores were divided evenly into five groups of three large glass test tubes each. Then each test tube was filled with 5.0 mL of liquid nutrient solution and either 0 mL, 0.5 mL, 1.0 mL, 1.5 mL, or 2.0 mL of methanol. The tubes were placed in an incubator at 28oC overnight to germinate, and then their aerial growth was marked beginning the next morning and every twelve hours thereafter for two days.
Table 1 shows the average growth data with 
In general, the results of the study suggest that Neurospora cultures prepared in liquid media can tolerate at least how many milliliters of methanol and still grow?
Explanation
Table 1 shows that the mold cultures still grow when 0.5 mL, 1.0 mL, or 1.5 mL methanol is added. The cultures do not grow when 2.0 mL of methanol is added. Therefore, the study suggests that the largest amount of methanol that the strains can tolerate is 1.5 mL.

Scientist’s believe they have found the gene accountable for intelligence. The allele “G” is dominant, and the allele “g” is recessive. The intelligence gene is optimally expressed in the homozygous recessive form. The chart above shows the trait in the heterozygous form and the homozygous form. The form “gg” is from the mother, and “Gg” is from the father. The parents want to know what the gene might look like in their child.
According to the chart above, what are the chances of the child inheriting the optimal form of the gene?
50%
25%
75%
100%
0%
Explanation
The optimal form of the gene is the homozygous reccesive "gg," which has a 50 percent chance of resulting from the parental cross.

According to the data given, what could one infer about the phenotype for "Gg?"
One cannot infer any phenotypic information about the form "Gg."
Individuals with the form "Gg" will be above the normal level of intelligence, but only partially.
Individuals with the form "Gg" will not exhibt any intelligence above the average.
Individuals with the form "Gg" will exhibit below optimal intelligence.
Individuals with the form "Gg" could exhibit two possible phenotypes. One phenotype is optimal intelligence; the other phenotype is average intelligence.
Explanation
The prompt does not tell what the phenotype of "Gg" is, it just mentions the phenotype for "gg" is optimal intelligence.

What genotypes would two parents want to have to increase their chances of a child exhibiting an optimal intelligence phenotype?
"gg" and "gg"
"gG" and "gg"
"Gg" and "GG"
"GG" and "gg"
There are various possible parental genotype combinations that could give the desired result.
Explanation
Two parents with genotype "gg" would create a 100 percent chance of having a child with the "gg" genotype, which results in the optimal intelligence phenotype.

The chart above shows the height growth of three different plant species after a period of 2 weeks. Each plant species was grown in 4 different soil mediums. All the plants were grown in the same environment with equal amounts of light, water, and oxygen.
What could be added to this experiment to improve the data representation?
All of the options listed would improve the data representation.
The chart should have a title.
The Y-axis on the chart should be labeled.
The data would be better represented with "Type of Plant" on the X-axis with four points above for each growth medium.
A supplemental chart listing the soil composition breakdown for each soil medium would be helpful.
