Meredith Robbins Ms. Sobota The Environmental Effects on Mitosis Research Question: How much of an effect does the IAA have on the rate of cell division in onion roots? Null Hypothesis: The IAA will not have a significant impact on the rate of cell division. Alternative Hypothesis 1: If the IAA is added to the water/ soil then it will have a higher rate on cell division. Alternative Hypothesis 2: If the IAA is added to the water/ soil then it will have a lower rate on cell division. IV: IAA DV: The rate of Cell Division Summary:

Name Period Chapter 1: Introduction: Themes in the Study of Life Begin your study of biology this year by reading Chapter 1. It will serve as a reminder about biological concepts that you may have learned in an earlier course and give you an overview of what you will study this year. In the overview, Figure 1.3 recalls many of the properties of life. Label the seven properties illustrated here, and give a different example of each. Concept 1.1 The themes of this book make connections across different areas of biology What are emergent properties? Give two examples. Life is organized on many scales. Figure 1.4 zooms you in from viewing Earth from space all the way to the level of molecules. As you study this figure, write in a brief definition of each level.

In a test of H0: p = 0.7 against Ha: p z 0.7, a sample of size 80 produces z = 0.8 for the value of the test statistic. Which of the following is closest to the P-value of the test? (a) 0.2090 (b) 0.2119 (c) 0.4238 (d) 0.4681 (e) 0.7881 2. An opinion poll asks a simple random sample of 100 college seniors how they view their job prospects. In all, 53 say ?good.? Does the poll give convincing evidence to conclude that more than half of all seniors think their job prospects are good? If p = the proportion of all

AP Statistics ? Chapter 14 Practice Test: The Chi-Square Distributions Part II, Free Response ? Show all work and communicate completely and clearly. 1. Computer software generated 500 random numbers that should look like they are from the uniform distribution on the interval 0 to 1. They are categorized into five groups: (1) less than or equal to 0.2 (2) greater than 0.2 and less than or equal to 0.4, (3) greater than 0.4 and less than or equal to 0.6, (4) greater than 0.6 and less than or equal to 0.8, and (5) greater than 0.8. The counts in the five groups are 113, 95, 108, 99, and 85, respectively. a. The probabilities for these five intervals are all the same. What is this probability?

?? Q 2 ? Stain the inner central pith sample in the same way. Draw a few of the cells that characterize what you see from each slide. Give a heading to each in the space below and label as many of the cell structures/organelles as you can find - can you see a nucleus? What might this indicate about the cell and gene expression, mRNA creation? Inner (green, stained) Outer (green, stained) ? 4) Complete steps 1-3 for the ripe and overripe banana samples. Draw your diagrams for each STAINED sample in the spaces below, BUT only do counts for ?outer cells.? ? Ripe Banana - With iodine stain INNER OUTER ? Overripe Banana - With iodine stain.
