Below is a section of a corncob. This represents the colors and shapes of the grains produced in the dihybrid F2 results of a cross. [the number of grains is not representative] The characters are ‘grain shape’ and ‘grain color.’ Round shape is dominant to wrinkled shape, and purple color is dominant to yellow color.     What is the expected genotype ratio for the F2 generation of a dihybrid cross?

A student carries out an investigation using catalase and hydrogen peroxide. The student mixed the catalase and hydrogen peroxide and recorded the amount of bubbles produced at different temperatures. The graph of the result is provided.   In this investigation, catalase was the [substance1] and hydrogen peroxide was the [substance2] The graph showed that catalase worked best at [temperature1]. According to the graph, approximately what [volume] of bubbles was produced at 20 degrees Celsius? (give your answer in mL)
