An individual is sailing off the coast of a remote area and is blown out to sea by a freak storm, which also destroys the main sails, damages the propeller, and disables the radio antenna. Aboard the boat are some minimal food supplies – some beef jerky, canned tuna, a roll of Life Savers candy – and an adequate amount of water. Assume that carbohydrate component of the sailor’s diet is severely restricted for several days until he or she is discovered and rescued but that he or she continues to eat adequate amounts of fats and proteins. Describe some of the adjustments that the person’s body would make to the unbalanced diet over this period of time?

Susan, 28-year young woman with type-1 diabetes mellitus has developed viral gastroenteritis. She is vomiting and feels very nauseous. She did not take her insulin and is increasingly becoming non-responsive. When she arrives at the ER, her pulse is 128 and her respiratory rate is 28, deep, and smells fruity. Her urinary glucose and ketones are very high. Her pH was dangerously low. Describe her symptoms in relation to type 1 diabetes. Explain how the kidney attempted to compensate for the low pH.

Thank you in advance :D

Short Answer Questions:

1. In my research, I found that the levels of “gonadotropins” in the body are critical to understanding how the drugs Clomid and Ortho Tri-Cyclen work. What are gonadotropins? What role do they play in fertility?

2. Some of the references talk about how “negative feedback” is involved in understanding how these drugs work. Can you explain what is meant by negative feedback?

3. My doctor told me that birth control pills contain small amounts of estrogen and progesterone, and these hormones prevent me from ovulating. I don’t understand how giving me these hormones in a pill would prevent me from ovulating. I assume that it has something to do with the levels of the gonadotropins that I asked about earlier. Can you explain this to me?

4. In the information about Ortho Tri-Cyclen, it mentions that the hormones in the pill make cervical mucus thicker and stickier. Does this happen during my natural cycle? How are estrogen and progesterone involved in this process?   

5. My doctor also explained that birth control pills “trick the body into thinking it is pregnant.” She explained that women do not normally ovulate when they are pregnant. Can you explain to me why a pregnant woman does not ovulate? How is this related to how the birth control pill works?

6. My doctor explained that Clomid works by “tricking the brain into thinking that estrogen levels in the body are low.” She explained that this is what leads to the extra stimulation of the ovaries to encourage eggs to be released. One of the references for Clomid said this happens because there is less negative feedback. Can you explain to me how this “trick” and the decreased negative feedback are related? Why would these factors lead to the stimulation of the ovaries?

7. My doctor told me that if I take Clomid, I would be taking it on days five through nine of my normal menstrual cycle. She explained that this is when it will have the greatest chance of stimulating the ovaries. What is going on during this part of the menstrual cycle that makes it the best time to take this drug?

8. I read an article that mentioned that women on Clomid may be more likely to get pregnant with twins, triplets, or more! The article said that normally there is a dominant follicle that releases a single egg, but Clomid can potentially make lots of follicles release an egg in a given month. How does Clomid do that?

Alain Pierre Dumas is young adult who was diagnosed recently after a car accident with an early form of Amyotrophic lateral sclerosis (ALS). He is terrified because he has no idea about this disease. He then turns to youan old friend in science major and asks you: 1. What is the cause of ALS? 2. do not experience any symptom at the moment. What symptoms & signs will eventually result in the future? 3. If ALS eventually gets worse and results to deathwhat would be the cause? Why? Be specific.

1)

TRUE or FALSE. Small volumes of air resonate to a higher frequency.

TRUE or FALSE. Large volumes of air resonate to a higher frequency.

TRUE or FALSE. Resonance initiates the vibration.

2A. What is the natural frequency of a female who’s vocal tract is 15cm long, closed at one end and opened at the other.

B. What is the second harmonic in question A:

c. Would the frequency change if both ends were closed with a vocal tract of 15cm? if so what would it be: (1) 11.46 (2) 573.3 (3) 1146.6 (4) 5.73 The pitch of a 4.5kHz tone= 2259 mels, which is 4500 Hz. (2 points)

3) Refer to the 50 phon line, and rank the following frequencies: 100Hz, 2000Hz, 7000Hz, and 10,000Hz beginning with the most sensitive frequency (least amount of intensity) to the least sensitive (most amount of intensity). (2 points)

100Hz___________dB
