delta Tf = i*Kf*m The expresssion for the freezing point depression of a solution relative to that of the pure solute is shown above.

delta Tf = i*Kf*mThe expresssion for the freezing point depression of a solution relative to that of the pure solute is shown above. From solutions of known concentrations of p-dichlorobenzene in cyclohexane, you determine Kf, the freezing point depression constant of cyclohexane. What assumption is necessary in order to do these calculations?

The cornea of the eye has a radius of curvature of approximately 0.500cm , and the aqueous humor behind it has an index of refraction of 1.

The cornea of the eye has a radius of curvature of approximately 0.500cm , and the aqueous humor behind it has an index of refraction of 1.35. The thickness of the cornea itself is small enough that we shall neglect it. The depth of a typical human eye is around 2.32cm . 1) What would have to be the radius of curvature of the cornea so that it alone would focus the image of a distant mountain on the retina, which is at the back of the eye opposite the cornea?2)If the cornea focused the mountain correctly on the retina as described in part A, where would it focus the text from a computer screen if that screen were 28.9cm in front of the eye?3) Given that the cornea has a radius of curvature of about 0.550cm , where does it actually focus the mountain?For part 1 it hints that this is not as a lens but a spherical object…

2) (9 pts) We have an Hfr strain that is gal + met + arg + amp S and we wish to map the relative position of the met and arg genes.

2)   (9 pts)  We have an Hfr strain that is gal+ met+ arg+ ampS and we wish to map the relative position of the met and arg genes.  We cross this strain with an F- strain having the genotype gal- met- arg- ampR.  We know from an interrupted mating experiment that gal enters last. Note that gal = a carbon source (galactose) while arg and met are amino acids. Amp = an antibiotic.

If you plate on the following media:

Media A)   minimal media lacking arginine but containing methionine

Media B)   minimal media lacking methionine but containing arginine

Media C)   minimal media lacking arginine and methionine

Media D)   minimal media containing arginine and methionine

You obtain the following results:

Result 1)   5% of the recombinants are arg- met-

Result 2)  10% of the recombinants are arg+ met-

Result 3)   0% of the recombinants are arg- met+

Result 4)  85% of the recombinants are arg+ met+

Match the media with the correct phenotype. 

What other chemical was in all the media? (why?)

Which gene is first?

How would you check to see if the galactose gene has moved?
