"Do you want leather or cloth seats?" asks the salesperson. "Do you want your baby to have brown or blue eyes?" asks the doctor. Genetic engineering has reached a point where, much like choosing a feature on a car before buying it, we can select the features of our baby before its birth. Features like height, eye color, hair color, intelligence, likelihood of illness, and more can be or will likely be selected soon. The question is, is it morally permissible to do so?
Discuss the moral implications of genetically engineering human babies. Respond to one of the following:
– Does it cheapen and commodify human life when we select the features of a human person like we do when purchasing a car? Contrast what a virtue ethicist would say according to its core principles of telos, virtue, eudaimonia, and practical wisdom with what a Kantian would say according to its core principles of universalizability, duty, impartiality, and reciprocity. Explain how one of these theories supports your answer. Is it morally different to use genetic engineering to lower the likelihood of illness, such as diabetes, as opposed to using it to select an aesthetic feature, such as eye color? Contrast what a virtue ethicist would say according to its core principles of telos, virtue, eudaimonia, and practical wisdom with what a Kantian would say according to its core principles of universalizability, duty, impartiality, and reciprocity. Explain how one of these theories supports your answer. Use appropriate textual evidence to back up your claim. Which of the ethical theories you discussed do you believe provides the best account of what the morally correct action to take is and why? (USLOs 8.1, 8.2, 8.3)
– Assuming genetic engineering remains expensive and only the wealthy can afford to engineer their children with more desirable features, such as greater intelligence and a lower likelihood of illness, is it morally permissible to allow genetic engineering? Contrast what a virtue ethicist would say according to its core principles of telos, virtue, eudaimonia, and practical wisdom with what a utilitarian would say using its core principles of welfare, impartiality, sum-ranking, and consequences. Explain how one of these theories supports your answer. Is it morally different to use genetic engineering to lower the likelihood of illness as opposed to using it to select increased intelligence? Contrast what a virtue ethicist would say according to its core principles of telos, virtue, and eudaimonia with what a utilitarian would say using its core principles of welfare, impartiality, sum ranking, and consequences. Explain how one of these theories supports your answer. Use appropriate textual evidence to back up your claim.

The effect of temperature on the benzoquinone production of catechol oxidase
Fanny Falcon, Ollie Burrowing Owl, Pete Prairie
BIOL1106.015
21 December 2012
Introduction:
Enzymes are biological catalysts that speed up chemical reactions. The reaction studied in this report is
catechol + oxygen – >> – benzoquinone + water. The enzyme involved is catechol oxidase. This is a
common reaction in fruit and vegetables that darken when cut. The product benzoquinone is dark. In
general, temperature increases enzyme activity because the molecules are moving more. The question
studied was ‘What effect does temperature have on catechol oxidase activity?’. The hypothesis tested
was ‘Catechol oxidase activity will increase with an increase in temperature’.
Materials and Methods:
Ten 13×100 test tubes were prepared following the mixing table in the instructions. 1mL of catechol
oxidase from prepared potato extract was added to each test tube. All tubes were placed in their
respective temperature baths for 5 minutes: 1&2 – 0C (ice), 3&4 – 27C (room temp), 5&6 – 40C water
bath, 7&8 – 70C water bath, 9&10 – 100C boiling water bath. All tubes were left in their temperatures
while 1mL of water was added to the odd tubes (1, 3, 5, 7, 9) and 1mL of catechol was added to the even
tubes (2, 4, 6, 8, 10). A square of Parafilm was used to cover and seal each tube. All tubes were inverted
to mix contents. All tubes remained in their temperatures for 10 more minutes. After time was finished,
each odd number was blanked on a spectrophotometer set at 540nm. The corresponding even number
was read. Absorbance readings for the even tubes were recorded. Tubes were inverted and wiped
down before inserting into the spectrophotometer. Tube 1 was blanked and tube 2 was read. Tube 3
was blanked and tube 4 was read. Tube 5 was blanked and tube 6 was read. Tube 7 was blanked and
tube 8 was read. Tube 9 was blanked and tube 10 was read.
Results
The absorbance numbers ranged from -0.16A at 100C and 2.38A at 40C. The lowest reading are negative
in the highest temperatures 70C and 100C. On a spectrophotometer, any time the sample is more clear
or lighter than the blank, the sample is read as negative absorbance. The darkest tube with the highest
reading was on the 40C tube. The absorbance readings changed with the different temperatures.
Raw data:
Tube Temperature Tube Contents Absorbance at 540 nm
2 0oC Ice Catechol oxidase & catechol Enzyme & Substrate 1.54
4 27oC Room Catechol oxidase & catechol Enzyme & Substrate 1.04
6 40oC Warm Catechol oxidase & catechol Enzyme & Substrate 2.39

The effect of temperature on catechol oxidase activity
Temperature C
Discussion
The hypothesis tested was ‘Catechol oxidase activity will increase with an increase in temperature’. The
data only supports the hypothesis in two readings 1.04A at 27C and 2.39A at 40C. None of the other
data supports the hypothesis. In general the data does not support the hypothesis. In repeating this
experiment, I would more quickly blank and read the tubes at the cold temperatures. I think the ice
tubes warmed up in my hands while waiting to use the spectrophotometer. I would do more repetitions
at each temperature and more temperatures. The change in absorbance between 40C with 2.39A and
70C with -0.02A is dramatic. I wonder what it would be like at every 5 or 10 degrees in between. I would
change the hypothesis. The higher temperatures denatured the enzymes and caused it to fall out of
solution. Each tube has a greyish precipitate at the bottom of the tube. The tube overall was a light
color showing none of the dark benzoquinone product seen in the cooler tubes. I would change the
hypothesis to ‘Catechol oxidase activity increases with temperature until extreme temperature
denatures the enzyme’. In conclusion, catechol oxidase activity varies with temperature.

According to a study reported by J Polit Econ, “For both men and women, the relationship is striking: a one-inch increase in height is associated on average with a 1.4 percent to 2.9 percent increase in weekly earnings, and a 1.0 percent to 2.3 percent increase in average hourly earnings.” On average, the taller we are, the more money we make. _This prompt will focus on the ethics of enhancement and not whether it is morally right for taller people to make more money than those with a shorter stature._
Enhancement surgery is now available to lengthen limbs so that a person can become significantly taller (six-plus inches). See the following video of a news story about a person who underwent this procedure. As the video states, these procedures are quite costly, ranging from $80,000 to $150,000.

Let's consider treatment versus enhancement. By treatment, we mean to restore a person's body to the status it would have without illness or injury. By enhancement, we suggest taking a person's body beyond the status it would have when free from disease or injury. Discuss the moral implications of pursuing enhancement surgery by selecting one of the ethical perspectives (prompts) below:
– Contrast what a virtue ethicist would say according to its core principles of telos, virtue, eudaimonia, and practical wisdom with what a utilitarian would say using its core principles of welfare, impartiality, sum-ranking, and consequences about the moral permissibility of human enhancements. Explain how one of these theories supports your view. Use appropriate textual evidence to back up your claim. (USLOs 6.1, 6.2, 6.3)
– Contrast what a Kantian would say according to its core principles of universalizability, duty, impartiality, and reciprocity with what a utilitarian would say using its core principles of welfare, impartiality, sum-ranking, and consequences about the moral permissibility of human enhancements. Explain how one of these theories supports your view. Use appropriate textual evidence to back up your claim. (USLOs 6.1, 6.2, 6.3)
