input: Please answer the following: Jenny goes to the doctor today. She has noticed a lump growing and needs to get a mammogram done. She is incredibly worried and not sure what she should do. Given a bacteria mutates to become resistant to an antibiotic, would this be considered a helpful or harmful mutation? Hint: Many mutations have no effect on the proteins they encode. These mutations are considered neutral. Occasionally, a mutation may make a protein even better than it was before. Or the protein might help the organism adapt to a new environment. These mutations are considered beneficial. An example is a mutation that helps bacteria resist antibiotics. Bacteria with the mutation increase in numbers, so the mutation becomes more common. Other mutations are harmful. They may even be deadly. Harmful mutations often result in a protein that no longer can do its job. Some harmful mutations cause cancer or other genetic disorders.

input: Please answer the following: While working on a touch screen laptop, Chris notices that his button presses seem to not be connecting where he presses on the screen. He opens up a calibration application and resets everything. The program then asks him to touch the screen where a button is in different locations on the screen. Will properly running the calibration application likely increase or decrease the accuracy of Chris' touch screen? Hint: When using measuring devices, we often use a technique called calibration to increase the accuracy of our measurements. Calibration is a method of setting or correcting a measuring device by matching it to known measurement standards. To better understand calibration, we will look at the example of calibrating a thermometer. All thermometers are slightly different in their temperature readings. One way to calibrate a thermometer is by using the freezing point and boiling point of water ( Figure below ). If we know that water freezes at 0C and boils at 100C, we can calibrate our thermometer by measuring the temperature of ice water and of boiling water. We place the thermometer in ice water and wait for the thermometer liquid to reach a stable height, then place a mark at this height which represents 0C. Then we place the thermometer in boiling water, and after waiting for the thermometer liquid to reach a stable height, we place a mark at this height which represents 100C. We can then place 100 equally spaced divisions between our 0 and 100C marks to each represent 1C. Our thermometer has now been calibrated using the known values for the freezing point and boiling point of water, and can be used to measure temperatures of objects between 0 and 100C.

input: Please answer the following: Medication A was tested on 1000 people for 3 years and cured Disease X in 80% of those trials. However, Medication B was tested on 50 patients and cured Disease X in 90% of those trials. Was Medication B's trial more efficient or less efficient than Medication A's trial? Hint: ANOVA generalizes to the study of the effects of multiple factors. When the experiment includes observations at all combinations of levels of each factor, it is termed factorial. Factorial experiments are more efficient than a series of single factor experiments and the efficiency grows as the number of factors increases.[45] Consequently, factorial designs are heavily used.

input: Please answer the following: Two brothers went to the doctor for their yearly examination. Liam found out he has high cholesterol, while Rudy found out his triglycerides and cholesterol are within normal parameters. Which brother was less at risk for heart disease? Hint: Cholesterol has been implicated in heart disease for decades. Atherosclerosis is a disorder of the arteries in which cholesterol and other materials are deposited on the interior of the arterial wall. These deposits lead to the formation of plaques that can restrict or even block the flow of blood through these blood vessels (see Figure below ). A decrease in the flow of blood can lead to high blood pressure and a lowered oxygen supply to the heart muscle. A complete blockage of blood flow to parts of the heart (a heart attack) can cause significant damage due to oxygen deprivation, in some cases leading to death.
