...1 What was the hypothesis of this experiment? Blood glucose concentrations in mice are lower when drinking primarily coffee than water. What question(s) was (were) the investigator asking? The question that the investigator was asking was why would the blood glucose increase in mice that primarily drank water then those who drink primarily coffee when water is the dis-solvent of life. Which is the control group? Why? The control group were the mice that primarily drank water because of the fact that they primarily drank water it separated them from the rest of the experiment. By the mice only drinking water, it did not subject them to a big change as those who only drank coffee and the investigators did not want to have some type of influence on the results from the mice that primarily drank water. Which is the treatment group? Why? The treatment group were the mice that primarily drank coffee because they were subjected to change and that change is what manipulated their blood glucose levels. Did the researchers follow the scientific method in their experimental design? Explain. The researcher followed the scientific method because they wanted to successful determine the cause and effect of drinking primarily water or primarily coffee on blood glucose levels. They completed the experiment in a way that the changes to the mice that primarily drank water didn’t affect...

...Organism Physiology: The Octopus Bio/101 January 17, 2010 Enteroctopus Dofleini or giant octopus is a marine invertebrate organism that inhabits the oceans off the coast of the United States. Its food source consists of crabs, small fish, clams, mussels and other marine animals. The octopus is predatory by nature and has developed many adaptations in the form of advance specialized organs to aid in its survival. The octopus has developed several organs that are vital to its survival, the brain/nervous system, complex eyes and arms for capturing its prey. In this paper the topic to discuss is these different organs and how they have adapted physiologically to its environment. The Giant Octopus has a considerably larger brain in comparison to other Mollusca which wraps around the esophagus and just below the optic socket. The brain, sense organs, and central nervous system are the most highly developed of the invertebrates. During its life span the brain will continue to grow and will consist of 170 million nerve cells, of which 130 million will be optical. 350 million nerve cells will reside in the arms of the giant octopus and can distinguish objects with the same sensitivity as its sight. As the octopus moves along the ocean floor, these nerve cells allow the octopus to learn its surroundings. The animal can remember its past environments and keep a working memory of areas they have...

...Ethidium Bromide Disposal Ethidium bromide is commonly used in molecular biology laboratories. While it is not regulated as hazardous waste, the mutagenic properties of this substance may present a hazard if it is poured down the drain untreated or placed in the trash. Based on these considerations, EHS recommends the following disposal procedures for ethidium bromide. * Electrophoresis Gels * Ethidium Bromide Solutions * Gloves, Equipment and Debris Electrophoresis Gels Trace amounts of ethidium bromide in gels should not pose a hazard. Higher concentrations, e.g., when the color of the gel is dark pink or red, should not be placed in laboratory trash. EHS recommends the following: * Less than 0.1% ethidium bromide: place in laboratory trash * More than or equal to 0.1%: place in biohazard box for incineration. Consider substituting with a less hazardous material, such as GelRed Nucleic Acid Gel Stain. Ethidium Bromide Solutions * Aqueous solutions containing <10ug/ml ethidium bromide can be released to the drain. * Aqueous solutions containing >10ug/ml ethidium bromide should be filtered or deactivated using one of the methods described below. EHS strongly recommends charcoal filtration over chemical deactivation. * Solutions containing heavy metals, organics, cyanides or sulfides should be disposed as hazardous waste. Charcoal Filtration Filtering the aqueous ethidium bromide waste solutions, free of other contaminants,...

...Organism Physiology Paper BIO101 April 15, 2014 Organism Physiology Paper The Sea Lion is the Organism that I want to discuss in this paper today. It has a highly controversial on weather this animal was a land walker only and when it actually acclimated to water, and why. After spending numerous hours researching this organism, it is still unclear to me when and why this animal changed its environment to include water. It is believed by many in the scientific world that the Sea Lion was a land dweller and became a water creature due to not have enough food in its land environment. “It's long been assumed that marine mammals in the pinniped group – seals, sea lions and walrus – evolved from a land-based common ancestor, but until now, no definitive fossil evidence had materialized” (Harmon, 2009). The animal would have had four legs that would have become webbed after its transfer to water. Its adaptation would have allowed it to survive under water for longer periods as well. The creature would have more than likely looked like the picture below if this is an accurate depiction of its ancestry. [pic] Its evolution would have included, being able to walk on land with paws that grip the earth, breathe air always to changing itself allowing it to breathe underwater and swim like a fish. Its paws slowly formed to fin like water movers however it...

...Evolution Lab BIO101 December 4, 2012 In this lab report it will evaluate a modern-day understanding of evolution using a link to analyze some data. The evolution website link will use numerical data to develop parameters that may influence a natural selection for researching and formulating a hypothesis. The data describes the results on Wallace Island and Darwin Island, testing one of the population mean, creating original parameters, and reproduction evolution. The formulating process uses both verbal and numerical hypothesis using the five-step hypothesis test on information pertaining to the selection per island. Finally, the outcome of the test will explain the how each result from this hypothesis testing is answer for Darwin Island and Wallace Island. The diversity and capacity of influence on the beak size and inhabitants number available data obligated to center on a matter discuss daily. A scientific theory necessitates that each theory be analysis under various conditions and meticulously. Any theory that continues to exist testing and may have led to a rejection is a well-built theory. Sometimes scientific evolution consists of classifying the circumstances under which a theory fails or holds like the size of beaks will influence inhabitant’s statistics. The beak size affects the diversity of the living organisms in a population with multiple numbers. After looking at the statistics over time the two islands speculates what may happen to beak sizes...

...The Natural Selection Process of Evolution “Darwin Island” and “Wallace Island” finches have survived many years on these isolated islands without much help from the human population. They are able to survive by adapting to their surroundings by a process called evolution. The evolution process begins with a process called natural selection. At this time, both islands are around the same size and the finches have similar populations and beak sizes. What would happen in 200 years if the “Wallace Island” shrank 0.2km and “Darwin Island” grew 0.2km and the clutch sizes for the finches increased by 4 eggs in size? Would the finches still have similar populations and beak sizes? Materials The material used for this experiment was my home computer and the Evolution Lab web link on the University of Phoenix Student Website. Methods and Procedures The first step in my methods and procedures was to login to the University of Phoenix Student Website. Next, I went into the materials link of my classroom and clicked on the web link for the Evolution Lab. Finally, once I am on the Evolution Lab website, I clicked “start lab.” After clicking start, the first step in understanding the natural selection and evolution process was to read the background information. Next, was to run a control experiment to see where the finches on “Darwin Island” and “Wallace Island” would be if nothing out of the ordinary happened. Once the control experiment was completed and the data recorded...

...Change in Precipitation Ramon Pena BIO101 February 14, 2011 Dr. Richard Steiner Change in Precipitation Introduction This experiment will take course during a 300-year-time -period simulation. This experiment will consist of two islands, Darwin Island, Wallace Island and take only into account the bird population of these two islands. The parameter will stay the same, except for one variable; precipitation. I will record how the precipitation changes the beak size of the bird population and what other effects it has on them. My hypothesis is that if the amount of precipitation is changed in one of the island then there will be more food. If there is more food in one of the islands then I can assume that more birds have access to more food, thus requiring a bird’s beak to stay the same while the birds from the other island have an increase in beak size due to the fact that they have to scavenge more for their food. Materials For this experiment, I will use a windows-based desktop computer with a 24-inch monitor for better viewing of graphs and simulations. I will also use notebook for recording cross time period information. Within the computer, I will be using a Java-based tool simulation, named Evolution Lab that will run the experiment and demonstrate the results. This will be the most important material for this experiment. Procedures First, this experiment takes place on a computer simulation called Evolution Lab. The Evolution lab can be accessed through the...

...Precipitation Effect on Evolution Introduction Precipitation can have rapid and lasting effects on an ecosystem and evolution of the life forms throughout the region. Too much precipitation can cause flooding, eroding shorelines, and rising sea levels. The effects of such activity wash away food sources and ultimately changes the way the various life forms will behave and survive. If weather patterns change and eliminate or drastically reduce food sources and habitats, it can bring various elements of the ecosystem to extinction. The route chosen for this lab was to change precipitation patterns and land size moderately for both islands to evaluate how this would affect the finch population and see if either island would be able to sustain a population of finch with excessive rain or a lack of rain. These types of climate changes are happening throughout the world and result in dramatic behavioral adaptation to adjust to the environment. Materials The materials used for this lab were a computer and access to the Evolution Lab that is found on the student website of the University of Phoenix. Methods and Procedures Using the scientific method the research provided background information that two islands have similar variables pertaining to the ecosystem, finch characteristics, and finch population. The question is will a change in the current precipitation pattern have a lasting effect on the finch population? The hypothesis is if the precipitation increases it will erode...

...The Evolution of Finches on Darwin and Wallace Islands Angela Vaughn BIO/110 December 9, 2013 Heather Browning The Evolution of Finches on Darwin and Wallace Islands In the 1800s, Charles Darwin, a brilliant scientist and naturalist, observed that an organism’s traits allowed it to adapt to an environment. These organisms would produce offspring that possessed abilities to survive in their environment. Those that did not possess these traits were less fit and were unable to survive the environment. This was the beginning of the study of evolution and natural selection. “Evolution is the study of how modern organisms have descended from the earliest life-forms and of the genetic, structural, and functional modifications of a population that occur from generation to generation. The ability of a population of organisms to respond to change in their environment and survive and reproduce by developing the characteristics or modifications necessary for survival is known as adaptation.” (University of Phoenix, 2013) House Finches live in dry desert, grasslands, stream sides and open coniferous forests at elevations below 6,000 feet. They eat seeds, buds and fruits. (House Finch, n.d.) The purpose of the experiment is to test my hypothesis, “Precipitation does not cause natural selection to act upon beak size.” Materials To complete the experiment, I will need access to a computer and the Evolution Lab simulation at the University of Phoenix website. The Evolution...

...Sierra Nevada Foothills Ecosystem Jamie Haymes, Clare Raimondo University of Phoenix BIO101 Travis Kibota Sierra Nevada Foothills Ecosystem The foothills of the Sierra Nevada are only a small section of the mountain range, encompassing the East and West slopes of the ranges in elevation from around 1,000 to 3,000 feet. The foothills are known as a biotic zone, one of five biotic zones, or ten if the person studying wishes to separate the Eastern side of the range from the Western side of the range. For our purposes, we will be including the Eastern and Western sides of the mountain range together as all being foothill zones. There are different types of species in the foothills of the Sierra Nevada; the producers, the consumers, and the decomposers. The Sierra Nevada Mountain Range’s foothills are at a low enough elevation that plant and animal life is adapted to hot, dry summers with very little or no snow in the winters. This type of dry climate leads to a lot of shrubbery and trees, which means there will be a large population of small animals and birds that will seek shelter in the shrubs and tree branches, as well as the larger animals that will feed on the plants and smaller animals. The plants that are typical to the foothills of the Sierra Nevada Mountain Range are numerous, but the most notable are the chamise, ceanothus, manzanita, Blue oak tree, Interior Live oak tree, and the Gray pine tree (Encyclopedia Americana, 2006). Chamise belongs to the rose family...
