Question 8
Which of the following statements is true?
SNPs do not account for any of the genetic variation in the human genome
SNPs are nucleotide polymorphisms that differ in a population
CNVs are not an important source in the variation of the human genome
All of the above statements are true
Question 9
Why are genetic changes that lead to a selective disadvantage usually lost?
Changes detrimental to survival can lead to fewer offspring and will not be passed on
Genetic repair mechanisms will erase the mistake
Organisms can control expression of deleterious genes to minimize impact
Sexual reproduction always purifies dangerous mutations
None of these are correct

The physician-to-population ratio technique compares the current (or preferred) ratio with the ratio likely to occur in a future period. What are some of the shortcomings of this ratio technique? (select all that apply)
a. The ratio technique fails to consider changes in demand for physician services
b. The ratio technique fails to consider changes in physician productivity
c. The ratio technique fails to include providers who offer services that are substitutes for physician services, including those provided by nurse practitioners and physician assistants.
d. The ratio technique fails to indicate the importance of a divergence in the two ratios being compared, such as the size of a shortage or surplus

Which of the following describes the condition known as runoff in the repricing model approach to measuring interest rate risk of an FI?
Select one:
a. The effect that a change in the spread between rates on RSAs and RSLs has on net interest income as interest rates change.
b. Mismatch of asset and liabilities within a maturity bucket.
c. The relations between changes in interest rates and changes in net interest income.
d. Those deposits that act as an FI's long-term sources of funds.
e. Periodic cash flow of interest and principal amortization payments on long-term assets that can be reinvested at market rates.

This question relates to standing waves.
A) Does a closed pipe have a higher or lower fundamental frequency than an open pipe of the same length?
B) If the length of an open tube is 0.8 m, experimentally find the: fundamental frequency and the frequencies of the third and fifth harmonic.
C) We have only addressed the variables of length, wave speed, harmonic number and frequency. These seem to be adequate to fully describe the frequency of a standing wave. But we know that when a musician tightens a guitar string, the frequency of the sound changes. Which of these independent variables changes value when a string is tightened?

MH, a 70-year-old woman with postoperative acute glaucoma, is prescribed one drop of latanoprost 0.005% ophthalmic solution each evening and one drop of timolol 0.25% ophthalmic solution each morning and evening.
After a few months on these medications, MH notices changes in the appearance of her eyes. Describe the changes that MH is likely experiencing, and explain which drug is responsible.

Problem 2 [6pt] In early implementations of Fortran language, a compiler may choose to use static allocation (i.e., allocation in the static area) for local variables and parameters, effectively arranging for the variables of different invocations to share the same locations, and thereby avoiding any run-time overhead for creation and destruction of stack frames. However, such implementation changes the meaning of recursive function calls. Write down a simple example and explain how its meaning changes under the “Fortran” semantics as stated above, compared with standard semantics found in language like C, Python, Java

FYI: I imagine the physics of thunderstorms involves wind stripping electrons from condensed water cells (raindrops or snowflakes). Like a Van De Graaff generator, sort of; I'm also using Wilson's cloud chamber concept of an ion at the core of a droplet. Not sure if global warming promises higher winds, but I think so.
Acceptable answers: will address the seemingly polynomial temperature dependence of the thunderstorm probability. Extra thanks if the answer says something about other contributions of expected climate changes (eg the faster, more severe changes in the weather, but not the rise in average global temperature).

Summarize the legislation that introduced Medicare and the funding source for the program. Discuss some of the changes that have occurred in the Medicare program since its inception. Describe the demographics of the population covered by Medicare and identify the number of people in the U.S. covered by Medicare. Assess how changes in Medicare will affect the citizens and legal residents in your state. Include specific demographic information on age, race, income, etc., for your state to justify your response.
Present your response in a 3- to 5-page Microsoft Word document formatted in APA style.
On a separate page, cite all sources using APA format.

b. What will be the bond’s price if rates in the market decrease to 1.98%.
c. Refer to your answers in part b. How do the interest rate changes affect premium bonds and discount bonds?
d. Suppose the bonds were to mature in 10 years. How do the interest rate changes in part b affect the bond prices?
