Evolution2 Evolution, a process of change through time, is what links together the enormous diversity of the living world. A lot of evidence is present that indicates that the earth has had a very long history and that all living things arose in the course of that history from earlier, more simpler forms. In other words, all species have descended from other species and all living things share common ancestors in the past. Basically, organisms are what they are because of their history. Today th

Female versus male recovery rate
female versus male recovery rate THE RECOVERY RATE OF THE MALE IS SIGNIFICANTLY FASTER THAN THAT OF THE FEMALE. Abstract: This experiment is designed to test whether or not gender is a major contributing factor to the recovery heart rate in humans. Most would assume that the male heart rate would be considerably faster in recovery time than that of the female. This experiment furthers that assumption by eliminating uncontrolled variables such as age, build, and health conditions. Introduction: T

While man has been so busy trying to find a way to get rid of all pain and suffering, he has finally discovered that there are things that cannot be stopped. This relentless phenomenon is called a genetic disorder. A ge

Genetic engineering has been one of the most controversial ethical issues since 1997; when Dolly the first successfully cloned sheep was announced. Dolly has redefined the meaning of ?dentical twin? not only does she look exactly like her mother she also has the same genetic make up. This experiment was not only impossible but unthinkable. Yet, Dr. Ian Wilmut revealed Dolly on February 23, 1997, at seven months old ( Travis

Enzymes help by catalyzing (speeding up) the reaction and intern lowering the activation energy required for the reaction to occur. Molecules called substrates bind with enzymes during reactions. However each enzyme has a very specific purpose. The shape of the active site on the enzyme’s outer layer determines that purpose, along with
