A current UC Santa Cruz graduate student who earned their biology degree at SFSU is doing research to replicate classic experiments that investigated the inheritance patterns of traits in the sweet pea plant. In one experiment, they mated a plant with wrinkled seeds (plant A) to a plant with smooth seeds (plant B). Of the resulting 100 offspring plants, they noted that 48 had wrinkled seeds and 52 had smooth seeds. Answer the questions below and make sure you fully explain your logic.

PART 1 (3 points):

Based on the results of the experiment above, can you conclude that the wrinkled phenotype is recessive to the smooth phenotype? Why or why not?

PART 2 (3 points):

In a subsequent experiment, they crossed two of the smooth pea plants that resulted from the original cross. Of the 100 offspring, 24 plants had wrinkled seeds and 76 had smooth seeds. Can you conclude from this which of the two phenotypes is dominant? Explain your reasoning.

PART 3 (3 points):

Based on the results of both crosses (in PART1 and PART2), what were the genotypes of the original two plants (plant A and plant B)? How did you figure this out?

The name of the experiment is Preparation of Synthetic Banana oil. The name of the author of the book is John Lehma. chapter 5.

(incase needed, we used 20.o mmol of isopentyl and 40 mmol of glacial acetic acid)

In the ''understanding experiment'' section, it was stated that the reaction of an equimolar mixture of isopentyl alcohol and acetic acid will produce, at most, 67% of the theoretical amount of isopentyl acetate. verify this with an equilibrium constant calculation, using K = 4.2 . b) compare this with the corresponding percentage for the conditions used in this experiment (see exercise 1 ) Please explain well.

Exercise 1 is also found in the book, however the ammount of chemicals used in the experiment are stated above. Thank you.

8) Describe the elements of an experiment. Describe the elements of a correlational study. What sorts of

questions does each type of study examine?

9) What is a

during the last century. Describe three differences between the experiences of your cohort and your

grandparents’ cohort.

In Arizona, all students in elementary and secondary schools have to take AIMS tests (which was largely replaced by AZmerit tests recently) as the state-mandated standardized assessment of math and English proficiency. A teacher wonders if high school dropout rate would be correlated with AIMS test results in a particular county. To explore this question, she collected the dropout rates and the AIMS Math pass rates (taken in 2012) at the county level for cohort 2014 from all counties in Arizona, as listed in the table below.

Calculate the Z scores for all the scores of AIMS English pass rate and high school dropout rate, separately. (please show work for a few so I understand how to do it)

An infinitely long solid insulating cylinder of radius a = 4.4 cm is positioned with its symmetry axis along the z-axis as shown. The cylinder is uniformly charged with a charge density p = 29 uC/m^3. Concentric with the cylinder is cylindrical conduction shell of inner radius b = 10.2cm and outer radius c= 12.2 cm. The conducting shell has a linear charge density = -0.33 uC/m.
