Biology HL -Functions of the Liver Essay The liver receives its blood from two main sources; the hepatic artery and the hepatic portal vein. The hepatic artery transports oxygenated blood from the left side of the heart through the aorta to the liver. The deoxygenated blood from the liver is drained back out through the hepatic vein which returns it to the vena cava. The hepatic portal vein carries nutrient rich blood from the small intestine to the liver. Its blood however

GloFish: More than just glowing. What is a GloFish? GloFish is a genetically modified animal‚ a fluorescent zebra fish. It is made and then advertised by Yorktown technologies. It is a genetically modified organism (or GMO). The fish got the fluorescence from a red fluorescent protein from a sea anemone under the myosin light peptide 2 genes of zebra fish. The new green colored fish got is color from the extracted Green Fluorescent Protein that is taken from one jellyfish species called Aequorea

Genetically Modified Crop Plants Biology 115 Genetically Modified Crop Plants Genetically modified crop plants and animals have great potential to change the world we live in. I believe that genetically modified crop plants can cure world starvation and at the same time improve the quality of food production. I recall when Senator Ron Paul was a presidential candidate in 2008 and student asked him his stances on genetically modified food products. His reply was “Big businesses

It’s what compels you to either flee from danger or address it head on. We often reward and cherish the instinct to fight while we shame those who follow the flight instinct.

one meter length of resistance wire‚ with uniform cross-sectional area fixed on a meter scale. Point D is an electrical contact that can be moved along the wire‚ thus varying the magnitudes of resistances R and S. The Carey Foster bridge is a modified form of the meter bridge in which the effective length of the wire is considerably increased by connecting a resistance in series with each end of the wire. This increases the accuracy of the bridge. While performing this experiment you will balance
