Protein A binds to the IgGs of different species of animals with variable affinity. What does this difference tell you about the Protein A epitope? a. the epitopes of the species are identical b. Some species lack IgGs and therefore cannot bind to Protein A c. the epitopes are similar, but with enough difference that it makes the affinity variable. d. The epitopes are very different in all the species Provide reasoning with your answer. d.

The amount of oxygen used by a house fly, at a steady temperature of 15°C, can be compared to its oxygen use at a steady temperature to 25°C. Knowing that increased temperature leads to increased biochemical reaction rates, and that flies are an incredible collection of biochemical reactions, you might reasonably predict that the rate of oxygen consumption by the flies is going to be higher at 25°C than it was at 15°C. In fact, the rate of increase for...

a) What is the “chicken tariff?” What does it have to do with light trucks and SUVs? b) Who benefits from the “chicken tariff” on light trucks? Why do you think the tariff is still in place? c) What do you think about U.S. consumers paying more for light trucks and SUVs or other products because of this? Whose interests should be the paramount concern of government trade policy: the interests of producers (businesses and their employees) or those of...

4. Using the equation, E -2.1797 x 108 n a. What energy does it solve for? b. What does n 1 represent? c. If an electron goes from n 4 to n 1, what is AE? 5. When you calculate AE using the above equation for two values of n, what does it tell you as to the absorption or emission of light of a specific color? What does this tell you about the movement and energy of an electron?
1. What does the time constant of an RC circuit that is being charged tell you?
Background Summary Questions: 1. What does the time constant of an RC circuit that is being charged tell you? 2. What does the time constant of an RC circuit that is being discharged tell you? 3. How is the voltage across the capacitor related to the charge on a capacitor? (Linear, Inverse, Quadratic, etc.) 4. Based on your answer to question 3, how would you write an expression for the voltage across the capacitor as a function of time? a. Charging: V(t) b. Discharging: V(t)= Background: The...

DATA 4.1 Does Light at Night Affect Weight Gain? Numerous studies have shown that exposure to light at night is harmful to human health. A recent study? examines the effect of light at night on body mass gain in mice. Eighteen mice were randomly assigned to one of two groups: the Dark group had a normal light/dark cycle with darkness at night and the Light group had a dim light on at night, equivalent to having a television set on...
