You are interested in studying resilin, a protein thought to be responsible for the ability of fleas to jump many times higher than their own length. this protein is purified and then analyzed as follows. fractions are collected from a gel filtration column that is a run with a buffer containing relatively low salt concentration. you collect 8mg of protein from these pooled fractions and discover that the protein contains 0.124mg of isoleucine and 0.209mg of glutamate after complete hydrolysis of the protein. isoleucine has a molecular weight of 131g/mol and glutamate of 147g/mol.
what is the minimum molecular weight of resilin given these data? show your calculations.

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).

When you see distant streetlights through smog, they look dimmer and redder than they do normally. but when you see the same streetlights through fog or falling snow, they look dimmer but not redder. use your knowledge of the interstellar medium to discuss the relative sizes of the particles in smog, fog, and snowstorms compared to the wavelength of light.

The frequency of a tuning fork can be found by the method shown. a long tube open at both ends is submerged in a beaker of water, and the vibrating tuning fork is placed near the top of the tube. the length l of the air column is adjusted by moving the tube vertically. the sound waves generated by the fork are reinforced when the length of the air column corresponds to one of the resonant frequencies of the tube. the smallest value for l for which a peak occurs in sound intensity is 7 cm. l what is the frequency of the tuning fork? the speed of sound in air is 345 m/s. answer in units of hz
