1. As a potential worldwide pandemic, avian influenza H5N1 (commonly called the bird flu) poses a serious health risk. As of January 24, 2012, there have been 583 human cases of this virus in the world. Of these cases, 344 resulted in death.(Source: http://www.who.int/csr/disease/avian_influenza/en/) Consider the outcomes of these cases as a random sample of all possible outcomes.

a) Find a point estimate for the proportion of people who would die if infected with the bird flu.

b) Construct a 90% confidence interval for the proportion of cases that would be expected to result in death if a pandemic occurred. Interpret the interval.

A 70 kg (154 lb) adult requires a calorie intake of 2,000 kcal (8,360 kJ) of food per day. The food is metabolized and the free energy is used to synthesize ATP for useful work. The efficiency of converting food energy into ATP is 50%.
1) Calculate the mass of ATP used by an adult human in 24h.

(ATP formula weight = 505 g/mol, DG'° = -30.5 kJ/mol)

2) If ATP is present at 5 mM inside cells, and if the intracellular volume corresponds to about 25% of an adult mass, how frequently is an ATP molecule hydrolyzed and rephosphorylated, on average?

2. From a vantage point very close to the track at a stock car race, you hear the sound emitted by a moving car. You detect a frequency that is 0.852 times smaller than that emitted by the car when it is stationary. The speed of sound is 343 m/s. What is the speed of the car?

3.Hearing damage may occur when a person is exposed to a sound intensity level of 90.0 dB (relative to the threshold of human hearing) for a period of 9.00 hours. An eardrum has an area of 2.71 x 10-4 m2. How much sound energy is incident on the eardrum during this time?

In the hunt to identify HTT, the disease-causing gene for Huntington’s disease (HD), it was discovered that human haplotypes A and C were highly associated with HD.

The DNA sequence variants geneticists used to detect haplotypes A and C were:

a) Extra repeats of a CAG codon located in the HTT gene

b) Single-nucleotide polymorphisms located near the HTT gene

c) Causal for Huntington’s disease

d) Not causal for Huntington’s disease

e) Located in the same chromosome region as one another
