Answer:
The P waves undergoes compression and dilation during motion in its direction of propagation. This waves reaches the station first because the P waves travels at a speed, that is much faster in comparison to the S waves. The S waves are the secondary waves and are commonly known as the shear waves.
The P waves have the ability to travel in both solid as well as in liquid, whereas the S waves can propagate only in solid region because they are absorbed at the core-mantle boundary.
Thus, the P waves will arrive the station first and the difference between the arrival of P and S waves are plotted in the graph that helps in depicting the epicenter and the amount of energy released during an earthquake.

Answer:
The bacterial pellet would have contained both isotopes, making it unclear which substance was the genetic material.
Explanation:
Bacteriophages are viruses that infect bacteria, those of the even T series (T2, T4 and T6). Hershey and Chase work with viruses that attack the enterobacteria Escherichia coli. Bacteriophages consisting of DNA viruses with a protein coat (capsid)
The infection process is that the virus injects its DNA into the bacteria. This viral DNA is inserted into the bacteria's DNA, which begins to make new copies (offspring) of the virus. After 25 minutes of injecting the DNA, the bacteria (host cell) explode, releasing hundreds of new bacteriophages. Since phages have only DNA and proteins, they were the appropriate tool to reveal the chemical nature of the hereditary material.
In 1952, Hershey and Chase designed an experience to find out if the inheritance was communicated by DNA or by proteins. They used radioactive labeling techniques to build two different types of phage populations (both T2). A population of phages grew in a medium containing the radioactive isotope S35. The S35 marks the proteins that contain the amino acids cysteine or methionine and therefore this population contains radioactive proteins and not radioactive DNA, since the DNA does not contain sulfur. The second population of virus grew in a medium containing P32. P32 marks nucleic acids, but not proteins, so that this population contains radioactive DNA and non-radioactive proteins. Both types of viruses were used separately to infect susceptible E. coli cells.
Nutrition labels diagram1 - Start with the serving information at the top.
This will tell you the size of a single serving and the total number of servings per container (package).
2 - Next, check total calories per serving and container.
Pay attention to the calories per serving and how many calories you’re really consuming if you eat the whole package. If you double the servings you eat, you double the calories and nutrients.
The next section of information on a nutrition label is about the amounts of specific nutrients in the product.
3 - Limit certain nutrients.
Check key nutrients and understand what you’re looking for. Not all fats are bad , and total sugars can include both natural and added sugars. Limit the amounts of added sugars , saturated fat and sodium you eat, and avoid trans fat. When choosing among different brands or similar products, compare labels and choose foods with less of these nutrients when possible..
4 - Get enough of the beneficial nutrients.
Make sure you get enough of the nutrients your body needs, such as: calcium, choline, dietary fiber, iron, magnesium, potassium, and vitamins A, C, D and E.*
5 - Understand % Daily Value.
The % Daily Value (DV) tells you the percentage of each nutrient in a single serving, in terms of the daily recommended amount. If you want to consume less of a nutrient (such as saturated fat or sodium), choose foods with a lower % DV (5 percent or less). If you want to consume more of a nutrient (such as fiber), choose foods with a higher % DV (20 percent or more).
Here are more tips for getting as much health information as possible from the Nutrition Facts label:
Remember that the information shown in the label is based on a diet of 2,000 calories a day. You may need less or more than 2,000 calories depending upon your age, gender, activity level, and whether you’re trying to lose, gain or maintain your weight.
When the Nutrition Facts label says a food contains “0 g” of trans fat, but includes “partially hydrogenated oil” in the ingredient list, it means the food contains some trans fat, but less than 0.5 grams per serving. So, if you eat more than one serving, you could end up eating too much trans fat.
The U.S. Food and Drug Administration (FDA) regulates the Nutrition Facts label seen on packaged foods and drinks. In 2016, the FDA released changes to the label to make it easier to see how many calories and added sugars are in a product and to make serving sizes more realistic. These changes are still being implemented throughout the food industry, so for now you may see the redesigned version shown here or the old original version.
