one process that is responsible for the evolution of adaptations of organisms to their environment.” (Futuyma‚ 2004) Inheritance is the theory initiated by Gregor Mendel who studied how offspring carry traits of biological parents. Any organism that is composed of similar units of organization is a cell. Matthias Schleiden and Theodor Schwann proposed the cell theory. Biological classification is the classification of living organisms. Bioenergetics is the theory that the same energy powers both living

first characteristic is that all living things are made of one or more cells. For instance living things are all multi-cellular‚ WE HUMANS‚ are multi-cellular. On the other hand though bacteria are unicellular but it’s also living. Multi-cellular organisms are made of many cells. The cell is the basic unit of life. The second characteristic is all living things display organization. Different parts of a cell are organized to do different jobs. Different parts of a body are organized to do different

have found that almost all living organisms have a gene that codes for a protein called Cytochrome C. This protein is important in releasing energy from food. Scientists study similarities such as the gene that codes for Cytochrome C in hopes to learn more about the universal genetic code and the relationship between living organisms on Earth. Procedure: The charts below lists a portion of the amino acids found in the Cytochrome C protein of several different organisms. Use the chart to compare the amino

Understanding Evolution: A Simple and Easy Illustration by Adam Chandler on Saturday‚ June 23‚ 2012 at 5:54am Many people don’t understand what evolution is‚ and how it happens. Therefore‚ some of them might reject it based on not knowing what it is‚ or based on a wrong understanding of it. Because of that‚ I find it my duty to make an easy to understand illustration of evolution‚ as I believe I understand it well. I’ll try to make this illustration as easy as possible‚ and in many places‚ oversimplified

that question‚ they have come up with two contradicting yet plausible theories‚ Creation and Evolution. The theory of Creation states that an intelligent being designed each organism. On the other hand‚ the theory of Evolution states that some form of stimuli sparked one of the earliest forms of life and that every single organism living today evolved from it. Starting with the evidence and the criticism for the theory of Evolution‚ this paper will provide the main arguments and criticism for both theories

tissue in living organisms is functionally organized‚ and because this organization is the product of evolution by natural selection‚ a major presumption of evolutionary psychology is that the brain‚ too‚ is functionally organized‚ and best understood in evolutionary perspective. It is clear that the body is composed of a very large number of parts‚ and that each part is highly specialized to perform a specific function in service of the survival and reproduction of the organism. Using the body as

While the definition of living organisms must be adapted‚ the majority of evidence leads to the classification of viruses as living organisms. Viruses are composed of a nucleic acid core‚ a protein capsid‚ and occasionally a membraneous envelope. The nucleic acid core is composed of either DNA or in the case of retroviruses‚ RNA

Out of the two organisms we looked at‚ my favorite is the Paramecium. Paramecium are grouped with protists because‚ like all protists‚ they’re single celled organisms. Paramecium fall under the Protozoa Phylum in the Protist Kingdom. If an organism is in the Protozoa Phylum category‚ that means it is a small microscopic organism‚ which Paramecium are as they can only be seen under a microscope‚ and it reproduces by binary fission (splitting in half‚ becoming two new organisms)‚ which Paramecium do
