Biography

I was a co-teacher in high schools for a couple years before I started working in the medical field. I did private tutoring for a couple months around that time as well. I'm 29 and have been taking science courses nearly every semester as well.

Linear Algebra and Its Applications

A homogeneous system of twelve linear equations in eight unknowns has two fixed solutions that are not multiples of each other, and all other solutions are linear combinations of these two solutions. Can the set of all solutions be described with fewer than twelve homogeneous linear equations? If so, how many? Discuss.

Biology

As shown in the figure, cyanide inhibits the electron transport chain by competing with O2 molecules for the cytochrome c oxidase heme group. Carbon monoxide (CO) has a similar effect. Both cyanide and carbon monoxide cause poisoning in victims of smoke inhalation.

Predict the effects of these poisons on the following properties of mitochondria just after exposure:
the pH of the intermembrane space
the concentration of NADH, and
the rate of production of ATP in the matrix.
Explain why you make each of the predictions on 1.-3. above.

A family that owns two automobiles is selected at random.Suppose that the probability that the older car is American is 0.80, the probability that the newer car is American is 0.70, and
the probability that both the older and the newer cars are American is 0.60.

a) Find the probability that at least one car is American (i.e. that either the older car or the newer car, or both cars are American).
b) What is the probability that the newer car is American, given that the older car is American?
c) What is the probability that the newer car is American, given that the older car is not
American?
