systems utilize free energy and molecular building blocks to grow‚ to reproduce and to maintain dynamic homeostasis. Living systems require both free energy and matter to maintain order‚ grow and reproduce. Organisms employ various strategies to capture‚ use and store free energy and other vital resources. Energy deficiencies are not only detrimental to individual organisms; they also can cause disruptions at the population and ecosystem levels. Biological systems must both capture free energy and

Biology 1010 is a course that introduces students to the basic biological phenomena in all living organisms. It focuses on the different molecular levels of organization‚ heredity in evolution‚ genetics and reproduction. Through this course‚ I was able to master three essential concepts such as Mendel’s Law of Segregation‚ enzymes‚ and photosynthesis. Gregor Mendel was an Augustinian monk that argued that parental traits are passed on to their offspring discrete “heritable factors”. Heritable factors

The big problems of the electoral system were particularly evident in the 2000 elections: There may have been significant discrepancies between the voter decision and the electoral vote; a candidate who obtains the most vote’s nationwide‚ does not necessarily have to combine the most electors. Al Gore won in 2000‚ the absolute majority of votes‚ but received fewer votes in the Electoral College as his opponent George W. Bush. Another disadvantage is the focus of the candidates on states where pollsters
