Hebert Spencer established the hypothesis that the society is like a biological organism and that a social structure is a living organism, Coser (1977). The writer outlines Spencer’s theory as well as the writer’s understanding on development. The relevance of Spencer’ theory will be mentioned by comparison of the similarities and differences towards a general theory of evolution. 1. Hebert Spencer’s theory The biological Organism Employing the organismic analogy that is, comparing organic…

Using my knowledge from class regarding the criteria for natural selection, I predict the parameter regarding heritability would have the greatest impact on the evolution of beak size in finches because this is the essential requirement necessary for an increase in frequency to occur by natural selection. Evolution is a result of natural selection, so without it evolution cannot occur compared to the other parameters. Also, a population cannot evolve if the trait is not able to be passed down…

“Darwin himself, in his day, was unable to fight free of the theoretical errors of which he was guilty. It was the classics of Marxism that revealed those errors and pointed them out.”-Trofim Lysenko. Lynsenko believed that Marxism, which has transformed into what we call Communism, was able to prove the scientific theory cannot be applied to society due to errors found with Darwin’s theory. When applying Darwin’s theory to society is as if the poor had not evolved yet to withstand challenges…

Arizona State Standards and District Standards: SC02S4 C2 PO 1. Describe the life cycles of various insects/ Butterfly/ Bumble Bee • SCO2S1 C1 PO 2. Predict the results of an investigation (e.g., in animal life cycles, phases of matter, the water cycle). • SCO2S1 C2 PO 1. Demonstrate safe behavior and appropriate procedures (e.g., use of instruments, materials, organism) in all science inquiry. • SCO2S1 C4 PO 1.

organisms that lack true tissue but have generalized type of cells, they lack a complex digestive, respiratory, circulatory and nervous system, they are generally sessile as adults and spend their lives attached to a fixed point. Cnidarians where the first organisms of movement, which have a nervous system called nerve net but no brain, their bodies have two cell layers, Cnidarians are mostly epitheliomuscular, whereby the epithelia cells contain contractile fibers that act as muscles. All…

Safranin. You use different dyes because Gram negative microorganisms have a higher lipid content and it’s soluble in acetone whereas gram positive microorganisms are less permeable after acetone and the crystal violet-iodine becomes trap inside the cells. When preforming this test or any other test it’s important to use your inoculating loop and…

Rachel Carson, a biologist, was the founder of the modern environmentalism movement during the 1960’s and 70’s. This movement spread quickly throughout the United States. Carson is known today for publishing her very famous book Silent Spring. This book was published during such an important time in history and is significant to this day because it tells us a lot about the environment we live in today. Many people have been fascinated by her book and several other pieces of work. She has…

Being products of evolution, nearly all living things are, in essence, products of their environment. The environment influences which traits are successful and get passed on. Before long, those organisms are directly products of their environment. This phenomenon chiefly occurs when the environment holds all the power over the organism. When it comes to humans, however, we are social animals, we influence and are influenced by those around us. Because of this, humans are not solely products of…

Jonathan Jeschke discusses a rapidly growing scientific discipline known as the four general hypotheses in modern Invasion Ecology. Ecology is defined as the study of interactions between organisms and their natural habitat. Jeschke elaborates using different methods of hypothesis to disclose an unambiguous image of each ‘backbone of science’ as a whole and individually and the ways it is beneficial to us. However, the most important influential invasion hypothesis I believe is Biotic Resistance…

In the article written by Julie Beck entitled “When Are You Really an Adult?” she uses a series of true life accounts to attempt to define when a person becomes an adult and what defines adulthood. She begins with the real life example of Henry David Thoreau and catches the attention of the reader by leading them down the path that she is talking about a current day young man. However, when she reveals she is talking of a young man of years past it is obvious that many different generations…
