(traits). * Another advantage of peas is that Mendel had strict control over which plants mated with which. * Each pea plant has male (stamens) and female (carpal) sexual organs. * In nature‚ pea plants typically self-fertilize‚ fertilizing ova with their own sperm. * However‚ Mendel could also move pollen from one plant to another to cross-pollinate plants. * In a typical breeding experiment‚ Mendel would cross-pollinate (hybridize) two contrasting‚ true-breeding

The debate on Creation vs. Evolution is a question of human origin. Were humans just created as an outcome of intelligence‚ or did we gradually just evolve throughout the years as a result of many cosmic accidents? How did we get here? Does it even matter? It most certainly does matter. One’s perspectives of on morality‚ justice‚ purpose‚ humanity‚ and destination are all intertwined to our views on human origins. Creationism is the belief that the existence of the universe and the origin of life

Divergent Evolution Evolution is the theory of organisms changing over time. The first two people to explore this theory were Charles Darwin and Alfred Russell Wallace. There are four types of evolution‚ those being adaptive‚ convergent‚ divergent‚ and co-evolution. Divergent evolution is when two or more animals originate from a common genetic base. To prove divergent evolution in animals‚ the Ursus Maritimus or polar bear is an example. Divergent evolution is when similar animals branch off

• Explanation of the concept of natural selection and how it takes place The theory of natural selection was developed by Charles Darwin and Alfred Russel Wallace. They suggested that the mechanism of natural selection was that some organisms have characteristics that are better suited to the environment they live in then others that don’t have these characteristics. These organisms are then more expected to survive to reproduce offspring with these characteristics‚ over generations new organisms

1. The science of biogeography is the description of distribution of life and the explanation of this description. The description is based on both time and space. This describes how things look and why they are there. It also looks to answer the question – are these features the same over time? Biogeography arose with the theory that life on earth is a non-random distribution. This is the most important observation leading to the field of biogeography. The study of biogeography includes many other

Temperature range Background: All organisms are adapted to a particular environment with its characteristic temperature range. The temperature range allows the organism’s enzymes to control its metabolism by operating at their optimum efficiency within this range. Some organisms are adapted to live at high temperatures (80 - 100oC) and these are called thermophiles

"An Ecosystem ’s Disturbance by a Pollutant Paul Cordova L. Lehr December 11‚ 1995 Freedman defines a pollutant as "the occurrence of toxic substances or energy in a larger quality then the ecological communities or particular species can tolerate without suffering measurable detriment" (Freeman‚ 562). Although the effects of a pollutant on an organism vary depending on the dose and duration (how long administered). The impact can be one of sublethality to lethality‚ all dependent upon the factors

Introduction Physics is a type of science that deals with nature of energy and substance. Physics goes head to head with evolution and creationism. There are many parts of evolution that deals with physics. These evolutions helps with creationist to prove both Dawkins’s and Nye’s theories wrong. Evolution is the method where earlier forms of living orgasms evolved and assorted themselves throughout the earth’s history. While creationism is the faith in the biblical view that living organisms

Eugenics: Diversity Beware Eugenics is a word derived from the roots of the Greek words meaning “good” and “origin‚” and originated from the author Francis Galton in the year 1869‚ in his book Hereditary Genius (Bouche and Rivard 2014). Eugenics is a form of artificial selection‚ and is the science of enhancing a population‚ specifically human populations‚ through regulated breeding of only those who are perceived to contain superior genes (Bouche and Rivard 2014). The idea behind the use of eugenics
