A group of scientists wanted to test the effects of Nitra-Grow, a chemical additive that can be given to plants to help them grow.  3 test groups of plants were given all the same time of sunlight, the same type of soil, and the same amount of water.  Plant A was given no extra chemicals.  Plant B was given 5g of Nitra-Grow.  Plant C was given 5g of Ammonia to see if Nitra-Grow worked any better than a basic nitrogen-based household product.  The plants are then measured on 5 consecutive days to find their average height (in cm).

On Day 7, what would be plant A’s approximate height?

Which plant is the control group? 

The table above shows measurements for tumor size growth over time within three different possible treatment methods. Each tumor was first documented at an initial size of 2 inches. Every month each tumor was measured, for a total of five measurements of each tumor. 

 Looking at the "Surgery and Chemotherapy" treatment column, where could one infer that chemotherapy was performed? 

Based on the table above, which single method is most effective at reducing tumor size in the shortest period of time?

The table above shows measurements for tumor size growth over time within three different possible treatment methods. Each tumor was first documented at an initial size of 2 inches. Every month each tumor was measured, for a total of five measurements of each tumor.  

What information would be most important to know before drawing conclusions based on this data? 

Based on the chart above, what conclusion could be drawn about the "no treatment" option?

What conclusion CANNOT be reached based on the data shown above?

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.

What form of the gene expresses optimal intelligence?

According to the chart above, what are the chances of the child inheriting the optimal form of the gene?
