Description

1. 400 L of water is at 4oC. If it took a heat source 600 seconds to heat this up to 6oC, what is the power rating of the heater?

2. A 95g cup of tea at 85oC is poured into a 1.25 L large tub of water at 30oC . What is the equilibrium temperature?

3. 150 g of ice at -10.5oC is raised to the melting point and then raised to 76.0oC. How much heat is added to the system?

4. A distant star is 7000 K and radiates 1.20 x1027 W. What is the star’s radius? Assume = 1.0.

5. On a warm summer day in California it can get as hot as 115oF, and on some cold winter days it can get as cold as -20oF. What are these temperatures in Celsius?

6. An aluminum sphere is 5.50 cm in radius. What is its volume expansion coefficient if it increases in volume 2.00 cm3 when heated from 100oC to 151oC?

7. Carbon 12 is defined such that 12g is one mole. So if a diamond is 37.5 g, how many moles of carbon are in it? How many molecules of carbon are in it?

University of Illinois at Chicago Southern and Western Blot Samples Questions

Use this information to match the list of probes to the 3 samples below:You have isolated several DNA sequences from a variety of mouse tissues. You have labeled each one of them with a radioisotope and will use them as probes on blots of several DNA and RNA samples. Below are a list of all the probes you generated (probes A through E) and a list of all the DNA and RNA samples that you will analyze (Samples 1 through 3)Beside each sample, write the letters corresponding to all the probes that will bind to a complementary sequence in that sample. These responses are graded all or nothing!List of probesProbe A: promoter sequence of a gene that is only expressed in the nervous systemProbe B: promoter sequence of one of the genes encoding a ubiquitously expressed histone proteinProbe C: coding sequence of a gene that is only expressed in the nervous systemProbe D: coding sequence of one of the genes encoding a ubiquitously expressed histone proteinProbe E: intron of a gene that is only expressed in the nervous systemList of samplesSample 1: Southern blot of genomic DNA extracted from adult mouse cardiac muscle system cellsSample 2: Northern blot of mRNA extracted from adult mouse nervous system cellsSample 3: Northern blot of mRNA extracted from adult mouse cardiac muscle cells

How the diazonium salt can bind to N,N-dimethylaniline with acetic acid and NaOH? Why we use brine? Why methyl orange shows a different color in the solution at a different pH? What is the pH range that methyl orange indicate? What were the pH in the 0.01M HCl and 0.01M NaOH solutions?

BSC 2086 USC Anatomy Respiratory Passageways Asthma Attack Matt Case Discussion

Part A: Matt stumbled into Maria’s apartment. It was 4 a.m. and completely dark. Unable to talk, he simply grabbed Maria’s foot to get her attention. She helped Matt onto the bed, slipping a mask over his face to deliver nebulized albuterol.Asthma is a condition caused by chronic inflammation of the small airways in the lungs. This leads to swelling and increased mucus production within conducting zone passageways. Due to the chronic inflammation, an asthmatic’s airways are already more narrow than the airways of an individual without this disease. Situations that may cause the airways to constrict or spasm are common. Exposure to dry and/or cold air, contact with pollen or other allergens, illnesses such as a cold or the flu, certain medications and foods, or even just stress can cause this bronchoconstriction to occur. This usually does not cause a problem for a non-asthmatic, but for someone with asthma, bronchoconstriction can severely decrease the diameter of the already swollen, mucus-producing airways, making it very difficult to move air into and out of the lungs. The decrease in air flow can range from mild to life-threatening, and may cause a great deal of anxiety for someone actively suffering from an acute asthma exacerbation, or asthma attack.Following his nebulizer treatment, Matt was breathing a little better and able to talk. He mentioned to Maria that he has been on a long-term asthma preventative – Advair. However, he forgot to take it for a while because he could not find the inhaler.Questions:Describe the anatomy of the respiratory passagewaysWhat are the three factors involving the airways that lead to an asthma attack?What is contained within a quick-relief rescue inhaler?What is nebulized albuterol, and how does it help with an asthma exacerbation? Part B: Please discuss the following topics. 1. Describe the power of the adaptive immune response to cure disease2. Explain immunological deficiencies and over-reactions of the immune system3. Describe the interaction of the immune and lymphatic systems with other body systemsAll reports will be worth 4% of your grade and will be 5 points each.
