Please answer this: Please answer correctly the following question related to the paragraph below. Which friend does not take a drug that induces the expression of low density lipoprotein (LDL) receptors in the liver? Brad and Henry were two old friends in their 70's. Brad had very high levels of cholesterol, while Henry was healthier and had normal levels of cholesterol. Hint: Currently, millions of individuals with high cholesterol take a similar type of drug, known as a statin. The drug, an inhibitor of HMG-CoA reductase (3-hydroxy-3-methyl-glutaryl-CoA reductase), the rate limiting enzyme in cholesterol biosynthesis, decreases blood levels of cholesterol by induce the expression of low density lipoprotein (LDL) receptors in the liver. The increased levels of the LDL-receptors stimulate the catabolism of plasma LDL, removing cholesterol from plasma, which is an important determinant of atherosclerosis. You may know of people who take a statin to help with their cholesterol levels. However, these drugs probably work slightly differently in many of those people. In some, it lowers their cholesterol significantly; in others it may lower it only moderately; and in some, it may have no significant effect at all. (Luckily for those individuals, there are multiple versions of the statins, so different drugs can be tested to find the proper combination for that individual.) Why the difference? Because of the genetic background of all people; the different single nucleotide polymorphisms that make us all different. Pharmacogenomics, a combination of pharmacology and genomics (the study of the genome) that refers to the study of the relationship between pharmaceuticals and genetics, may explain and simplify this problem.

Please answer this: Please answer correctly the following question related to the paragraph below. Does Vader have more or less fusion reactions in the shell around its core than Enterprise does? Two stars have just been discovered that are identical in terms of chemical composition. The scientist who discovered them was given the right to name them, and he chose the names Enterprise and Vader. As said before, these stars are very similar, but the main difference is that Vader is a red giant, and Enterprise is not. Scientists are very eager to study these two newly discovered stars and see if they can learn anything new from them. Hint: A red giant star is a star with a mass like the Sun that is in the last phase of its life, when Hydrogen fusion reactions in the core decrease due to the lack of fuel. With the gravitational collapse of the core, the fusion reactions now occur in a shell surrounding the core. The outer layer of the star expands enormously up to 1000 times the size of the Sun. When the Sun becomes a red giant, its volume will include the orbit of Mercury and Venus and maybe even Earth. The increased size increases the luminosity even though the outer layer cools to only 3000 K or so. The cooler outer layer causes it to be a red star. After a few more million years, the star evolves into a white dwarf-planetary nebula system.

Please answer this: Please answer correctly the following question related to the paragraph below. Whose pot of water is colder? While out camping, Susie and Bob both make their own campfires to cook food on and keep warm. Susie puts a pot of water on her fire to use for coffee, and Bob puts his own pot of water on top of his fire. Suddenly, an odd man comes up and asks if he can measure their water pots for his scientific research. Hesitantly, Susie and Bob both agree, but feel odd about the situation. The man tells them that Susie's water molecules are moving very fast and Bob's aren't moving much. The man then sprints away. Bob and Susie look at each other with confused expressions. Hint: We discussed earlier some basic principles about the behavior of gases called the kinetic-molecular theory. Among other things, this theory suggests that gas molecules are in constant motion, and the average speed of the individual gas particles is dependent upon temperature the higher the temperature, the faster the molecules move. It is not just gas particles that are in constant motion. The molecules and ions that make up liquids and solutions are also continually moving in nearly random directions. As a result, molecules and ions in a solution will collide with one another fairly frequently. As with gases, a temperature increase will produce an increase in the average particle speed.
