Test Tube Degrees Celsius
1,267 wordsEnzyme Action: Testing Catalase Activity Enzymes are proteins that serve as catalysts and accelerate chemical reactions in living organisms. Enzymes accomplish this by lowering the energy of activation of the organism it is acting upon, however enzymes will only lower the energy of activation for specific organisms, reducing chaotic chemical reactions. The reaction is carried out in its entirety in the active site of the enzyme. The substrate (organism acted upon), binds itself into the active s...

Soil Erosion Human Actions
1,131 wordsSoil erosion is a gradual process that occurs when the actions of water, wind, and other factors eat away and wear down the land, causing the soil to deteriorate or disappear completely. Soil deterioration and low quality of water due to erosion and run off has often become a severe problem around the world. Many times the problems become so severe that the land can no longer be cultivated and is abandoned. The key to minimizing soil erosion and saving the farm lands is the farmer himself. Ultim...

Carbon Dioxide And Water Organic Compounds
791 wordsHave you ever wondered why your plants in your house and outside lean towards the sun. In my project I hope to answer why this happens. I am going to be using lima beans to do this with. The Greek philosopher Aristotle may have been the first to attempt to explain the processes of photosynthesis and food production. He believed that plants could obtain from the soil all the components required for growth. The cycle was completed when organisms perished and became reincorporated into the soil. Th...

Theory Of Evolution Origin Of Species
887 wordsBefore November 24, 1859, many people simply believed that species were created by God in their present forms, or that it was possible for organic matter to be spawned from inorganic matter. However, Charles Darwin used these ideas to create his thesis, On the Origin of Species by Means of Natural Selection. The first true theories on evolution arise during the classical Greek period. On a handful of Greek philosophers believed in the theory of evolution and natural selection. Unfortunately, the...

Micrometers Per Minute Specific Genes Required Mgl
546 wordsThe bacteria Myxococcus Xanthus is a decomposer that moves and forms fruiting bodies to reproduce. These fruiting bodies are mounds that grow into mushroom cloud like bodies, where cells differentiate on the inside to form small spores that are heat and desiccation resistant. In her discussion of Myxococcus Xanthus, Dr. Hartzell addresses various complexes that make flagella-less movement possible for the bacteria. The researchers traced cell movements and found that Myxococcus Xanthus moves at ...

Life On Earth Origin Of Species
877 wordsBiology came of age on November 24, 1859, the day Charles Darwin published On The Origin of Species by Means of Natural Selection. His book presented the first convincing case for evolution and led the way in the emergence of biology from a bewildering chaos of facts into a cohesive science. In biology, evolution refers to all the changes that have transformed life on Earth from its earliest beginnings to the seemingly infinite diversity that characterizes it today. Darwin addressed the sweeping...

Hurricanes And Typhoons Uv Radiation Air
332 wordsAir surrounds the Earth, giving it protection from the constant battering of meteorites. It provides a shield against the UV radiation of the sun so that the organisms can survive. It also makes itself available to be breathed in by animals. Yes, we need the air, otherwise known as the atmosphere; or else wed be nothing. However, the atmosphere can have its ugly side. Tornados, hurricanes and typhoons move through things we have painstakingly built, clearing it all away. They sometimes even take...

The Human Genome Project
727 wordsA genome is all the DNA in an organism, including its genes. Genes carry information for making all the proteins required by all organisms. These proteins determine, among other things, how the organism looks, acts, processes and fights infections. DNA is made up of four similar chemicals (bases, adenine , Thymine
, cytosine , and guanine ) that are repeated millions or billions of times throughout a genome. The human genome has three billion base pairs. The order of these base pairs...

Sense Of Individuality Organ Transplants
1,080 wordsA clone is the name given for a group of organisms or other living matter with exactly the same genetic material. Genetic material consists of genes, which are the parts of cells that determine all characteristics of living things. It is not until recently that scientists have developed an experimental process for cloning higher animals, such as humans. This is a very technical process which involves first destroying the nucleus of an egg cell from the species to be cloned. Then a nucleus is rem...

Life On Earth H 2 O
726 wordsThe first thing water reminds us of is the clear liquid in our water bottles. However, water is more than a normal substance. Water is the beginning and the continual of life on earth. Because of its many unique properties, water was able to start life on our planet. The simple structure of H 2 O is the source of all water's properties. With two hydrogen atoms sticking to an oxygen atom in a tetrahedron shape, water is considered as a polar molecule. Because oxygen is very electronegative, it pu...
