‘Wall Street’ flawed‚ but don’t sell Gekko short “They love that quality of take no prisoners ... if I have one more person‚ it’s so depressing and sad‚ they come up to me and say‚ you know‚ you’re the reason that I got into Wall Street ... that’s a‚ that’s a sad commentary.” —Michael Douglas There is a fabulous irony to “Wall Street” that perhaps can’t be adequately explained. The movie is an unequivocal denunciation of Wall Street excess but remains the preeminent film of those

bacteria‚ firmly adhere the smear on to the microscopic slide to prevent washing off during staining‚ and to allow the sample to readily take up the stain. Reference: www2.hendrix.edu What is the purpose of heat- fixing the smear? It helps the cells adhere to the slide so that they can be stained. The purpose of heat fixing is to kill the organisms without serious distortion. They adhere better to the slide and also take up dye more easily. Fixation process Fixation is usually the first stage

plant cells that are farthest from the light‚ are plant hormones with a variety of functions including embryonic development‚ leaf formation‚ apical dominance and root development. Relative to the process of phototropism‚ auxins transport protons by activating proton pumps which consequently decreases the pH levels in the cells on the darker side of the plant. This region becomes more acidic and activates enzymes known as “expansins”‚ which break bonds within the cell wall structure. The cell wall

termites and cockroaches. On February 6‚ 2013‚ scientists reported that bacteria were found living in the cold and dark in a lake buried a half-mile deep under the ice in Antarctica. There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water; in all‚ there are approximately five nonillion (5×1030) bacteria on Earth‚ forming a biomass that exceeds that of all plants and animals. Bacteria are vital in recycling nutrients‚ with many steps

The Great Wall of China is one of the greatest architectural achievements ever recorded in history. The Great Wall translates to “long fortress.” The wall was made entirely by hand. It was built to protect the Chinese from intruders from different Nomadic Tribes. The wall is about 5‚500 miles long. The wall did not stretch across all of China but it stretched from Shanhaiguan in the East to Lop Nur in the West. Some people say that you can even see the wall from the moon! Wouldn’t that be something

attracted to the surface of a bacterial cell (due to ionization of the carboxyl groups in the fatty and amino acids present in the cell wall/membrane). Basic dyes are attracted to the nucleic acid component of the bacterial cell‚ as well. As a general rule‚ acidic dyes are attracted to basic (alkaline) subcellular components. The most common stains used to stain bacteria are basic dyes. The most common background stains are acidic dyes since they do not cross the cell wall/membrane particularly easily. A

having sickle cell anemia can make a person more resistant to contracting malaria If it had not been for Anthony Allison‚ the world as we know it today would drastically change. Like the video stated‚ many people with the sickle cell anemia would meet “death before adulthood”. Areas with high frequencies of anopheles mosquito and sickle cell anemia would correlate but nobody would understand why. I admire Allison for not only having the burning inquiry to determine why the sickle cell anemia character

of sugar on texture and flavour of cooked fruit and enzymatic browning. Both fruits and vegetables have cell walls that are distinguished by having a rigid structure‚ with a primary cell wall and a secondary cell wall (Yuan‚ 2014b). In the primary cell wall‚ there is cellulose and hemi-cellulose‚ both of which are digestible and not very soluble (Yuan‚ 2014b). In the secondary cell wall‚ there is lignin‚ which is in older plant material and gives it a woody texture (Yuan‚ 2014b). Enzymatic

wood-decay fungi attack dead wood‚ such as brown rot‚ and some‚ such as Armillaria‚ are parasitic and colonize living trees. (Raven and Johnson‚ 2011) Wood decay fungi can be grouped in different ways: according to their mode of attack on the woody cell walls‚ by their general biology‚ pathogens‚ parasites or saprotrophs and whether they are primary or secondary colonisers. Wood-decay fungi can be classified according to the type of decay that they cause. The can be grouped into three distinct groups
