4. Answer the following questions about photoinhibition and the xanthophyll cycle:
a) What is photoinhibition? How are reactive oxygen species (ROS) involved in photoinhibition?
b) How can photoinhibition “protect” the photosynthetic apparatus from further damage?
c) How does the xanthophyll cycle operate? How do xanthophylls contribute to the defense against excess light?

Identify the 4 valves of the heart and explain its location as well as its function. Explain the word parts that comprise these terms and how their function is related to their meaning. Choose two specific components of the cardiovascular system and explain how they contribute to the overall function of the cardiovascular system. Finally, list two diagnostic procedures of the cardiovascular system and explain each of the word parts that make up those procedures.

Meiosis is a process that can generate nearly infinite variation from a single source of genes, even before the additional diversity created by fertilization. There are two main processes that occur during meiosis to generate diversity. Describe each of these processes, referencing where in the meiotic cycle they occur and how they contribute to genetic diversity in the gametes. Format your answer into parts (i) and (ii) for the two processes.

Monica has decided that she wants to build enough retirement wealth that, if invested at 10 percent per year, will provide her with $5,500 of monthly income for 25 years. To date, she has saved nothing, but she still has 30 years until she retires. How much money does she need to contribute per month to reach her goal

You wish to have $250,000 at the end of twenty years. In the last five years, you withdraw $1,000 annually at a rate of 3.8% compounded quarterly. During the middle ten years, you contribute $500 monthly at a rate of 2.8% compounded semi-annually. Given this information, determine the initial deposit that has to be made at the start of the first five years at a rate of 4% compounded monthly?

Researchers plan to study the weight gain of cows during a 3-month period. They wish to test at alpha = 0.01 if the mean weight gain exceeds 15 kg. Further, it is important for the researchers to detect if the mean weight gain is as large as 27 kg. An earlier study indicated that the standard deviation of the weight gains was around 14 kg. Since weight gains are normally distributed a t-test is to be used.

(a) If the researchers used a sample size of 22 what would be the power of the test in detecting if the mean weight gain is as large a 27 kg? Use R, showing the command you used and the result.

(b) Use Table 21 to determine the sample size required in order to have a power of 0.99 to detect if the mean weight gain is as large a 27 kg.

The collected data is from two 4th grade (All female classes - Age 10) Fitnessgram pacer tests. Once you have analyzed the data, please answer the following questions.

1. What was the mean, median, and mode for each class?

The postanesthesia care area (recovery room) at St. Luke’s Hospital in Maumee, Ohio, was recently enlarged. The hope was that the change would increase the mean number of patients served per day to more than 25. A random sample of 15 days revealed the following numbers of patients.

At the 0.01 significance level, can we conclude that the mean number of patients per day is more than 25?
