The Scientific Method

1) What is the problem you are trying to solve?
Whether light or dark colors would be more comfortable to wear on a hot, sunny day?

2) What is the prediction you want to test?
Light colors are more comfortable to wear on a hot, sunny day?

3) How will you use the computer model to test your hypothesis? What steps will you follow? What data will you record?
I will plug the jackets up to the 60 watts and test its temperature. The steps I will take is comparing the light and dark colors of the same material. The date I will record is who had the hottest temperatures and the dark colors had the hottest.

4) Analyze the results of your experiments.
With the data I receive it is obvious dark colors observe the most heat.

5) Draw a conclusion. Did the results of your experiment support your hypothesis? Why or why not?
My conclusion is it is more comfortable to wear lights colors than dark colors on a sunny day. Yes my results supported my hypothesis because I predicted it would be hotter with dark colors and the hotter you are on a sunny day, the more uncomfortable you are.

6) How does the material of the jacket affect the heat absorption?
A material's color affects its ability to absorb light. An object of a certain color reflects that same color but absorbs light from all the other colors. Since light is energy, the more light that an object absorbs, the more heat it absorbs.

7) Describe thee strength and weaknesses of the computer model you used in the experiment. What other parameters could you use in such an experiment to determine the effect of color on heat absorption?
The strength was the plugging the jackets to the 60 watt and letting me know what colors absorbed the most heat. There wasn’t a weakness. Try using thermometer strips sold at pet stores (to stick on the insides of reptile cages to monitor temperature). Also try some materials with different reflective surfaces too (foil; shiny black vs. rough-surfaced black for example).

What Biopsychology

...Mickesha Holden Mr. Smith Intro to PSY 9 march 2016 What is biopsychology? Biopsychology is a part of psychology that deals with the study of the human brain, human behavior and how it may or may not be affected by genetics.Biopsychology is the study of the biology of human behavior. This science mostly involves the study of biology such as genetics and what affects it has on human behavior. Biopsychology also includes the study of understanding the link between the mind, body and brain and how they interact with one another; how the bodies will respond to brain activity. Biopsychology can be traced as far back as Avicenna who lived in (980-1037) C.E. he was a physician who realized there was a connection between the treatments of an illnesses and emotions: “developed a system of associating changes in the pulse rate with inner feeling, which is seen as an anticipation of the word association test. Avicenna also gave psychological explanations for certain somatic illnesses…” (New World Encyclopedia contributors). Many years has passed biopsychology was seen as scientific and later arise from many different scientific and philosophical traditions in the 18th and 19th century, During this time it was the roman church who determined a lot of the behavior because of their religious beliefs. After the middle ages people had found a new way of thinking. This change in life style started during the renaissances, which is considered the link between the dark ages also known as...

...Assignment#1 BY: Khalleef Harewood Professor Leah Miller INTRO TO BIOLOGY- SCI 115 Gene mutation is known as a permanent change in DNA. For a three year old this can have a tremendous effect on life for oneself and for a family. The article that I had the opportunity to have read was “Rare gene mutation could claim three-year-old's life” (Jim Bender). The three year olds name is Kaylee. She has been diagnosed with a rear gene mutation enabling her from being able to talk, walk or have the mobility of her own head. She is one of only two children in North America to have this condition. The gene that has gone array is a gene that assists the body in dealing with physical stress and has no known cure. Gene mutation relates very well with this course because it directly reflects our discussions about DNA and the many processes it goes through especially DNA replication and repair. “DNA replication is the process by which a cell copies its DNA” (Study Guide, 2013, p105). Based on the concepts from the course after the process called semiconservative replication, which is the process, that when “one strand of each molecule is parental (old), and the other is new”(Study Guide, 2013, p106). After the strands have been duplicated they form bases and in some instances an incorrect base is added during the replication process. This process is very fast due to DNA polymerases working capability. Just as any fast working part of any kind of machine or person,......

Gene Technology

...Gene Technology Nelly Solorzano Strayer University SCI115008VA016-1158-001 Intro to Biology Kerry Lee November 29, 2015 Gene Technology Biological basis - Genetic engineering is a laboratory process by which an individual genome is purposely modified. With genetic engineering a gene from one species can be transferred to another and produce an organism that is transgenic or a gene can be altered and reinserted into an individual of the same species. Either way resulting in genetically modified organism also known as GMO. One GMO being used now is genetically modified or engineered animals which are animals in which modern technology and molecular biology are used to alter their existing characteristics or traits. Genetically modified animals are used for various purposes the biggest one now is bio pharma meaning they are intended to produce substances that can be used for human or animal pharmaceuticals. There is also a development of genetically modified animals for the use of scarce cells, tissue, or organs for transplants into humans known as xenotransplantation such as organs from pigs who are a potential source of organs for transplant. The benefits genetically modified animals can produce depend entirely on the traits that are introduced, for example some animals can be made to grow faster and therefore requiring less food to sustain them other animals have improved fat composition providing a more healthful nutrient profile. As of now no genetic......

Liberal Arts Breadth and My Education

...LIBERAL ARTS BREADTH AND MY EDUCATION 3 Liberal Arts Breadth and My Education There are many benefits to getting a Liberal Arts degree in today’s economic market. It is a message to your employer that you are willing to take on new information, and learn more then what is necessary to succeed. It shows initiative and the ability to expand your horizons beyond yourself. In a Liberal Arts education there is more purpose then just learning the career field of choice. It is a program that teaches critical thinking and self-thought. It teaches the student how to learn and teach themselves, to achieve more than just memorization of facts. In the Ottawa University Liberal Arts degree they have four breadth areas that are required for completion of their program. The breadth areas are as follows: Art/Expression, Social/Civic, Science/Description and Value/Meaning. Art/Expression According, to the official curriculum laid out by the school this category is that is highly concentrated in being capable of expressing self through art or speech. It spans from painting, to music, dance, language and communication. The manual’s description is, “how we express ourselves in spoken and written communication and the arts, looking at strengths, experiences, and new opportunities for challenge and growth.” Like, most people art has always been a part of my life. It followed me through my elementary school years to high school. I took ceramics, painting and woodworking 1, 2, 3, and 4......

Neuroengineering

...Amy Le Intro to Biomedical Engineering Ting Chen November 30, 2012 Neuroengineering Neural engineering, alternatively written as neuroengineering, is defined as an “interdisciplinary research area within biomedical engineering” that engages both neurological and engineering methods to unveil neural functions and “design solutions for neurological dysfunction” (Avramut). Since the period of Enlightenment, advancements in science and technology have been known to greatly improve the understanding and knowledge of the universe and how it functions. However, as groups started to interpret this further gain of knowledge as going to far because it went beyond what their religion taught them or interrupted their morals. Neural engineering follows the same path as any other science, ethically and practically. Some applications of this technology that arises controls your brain and can change how you act or feel. Ultimately changing our character and who we are at the “core”. In addition to striving to attain a deep understanding of complex neural systems and mechanics, neuroengineers use these methods to apply to their research or design to eventually control the brain, thus fully understanding how it works. One research project is going towards trying to find a way to make a mood switch and installing it into the human brain. This is especially beneficial to those suffering from depression. Depression, from a neurological standpoint, is a medical condition in which......

Formal Lab Report 2

...Sean Cui Biology Formal Lab Report 2 Intro Throughout this lab, the main topic is genetic transformation. Genetic Transformation is a phenotypic change caused by genotype change from transferring foreign genes into an organism. This lab is to transform the bacteria E.Coli with the GFP gene (Green Fluorescent Protein). GFP makes organisms glow in the dark with UV light, similar to jellyfishes.GFP will be transferred into E.Coli through the use of recombinant DNA, or simply a vector. A vector is a plasmid that transfers foreign DNA into cells. Bacteria can transfer plasmid to other bacteria so they can survive and adapt to the environment they are in. The pGLO plasmid includes the GFP gene (allows bacteria to glow), Beta-lactamase (resists ampicillin), ORI sites (allows bacteria to self replicate), and AraC (allows induction of GFP gene). Materials and Methods: In this lab, first there will be two micro test tubes, one labled pGLO+ and the other pGLO-. Using a sterile transfer pipet, transfer 205 microliters of CaCl2 into each tube. Then put the tubes on ice. Then use a sterile loop to pick up a single colony of bacteria from the starter plate. Put the colony in the pGLO+ tube and spin the loop. Then put the tube back in ice. Repeat this for the pGLO- tube with a new sterile loop. Next use a new sterile loop and get some DNA stock. With the loop, immerse it in only in the pGLO+ tube. After that, incubate the tubes in ice for 10 minutes. Label one plate LB/amp......

Genetic Testing for Alzheimers

...Genetic Testing for Alzheimer’s Disease Breanna Selzler Rasmussen College Author Note This paper is being submitted on June 20, 2014, for Greg Barnett’s G215 Intro to Human Biology course. Genetic Testing for Alzheimer’s Disease Alzheimer’s disease is a type of dementia that causes problems with memory, thinking, and behavior. Symptoms usually develop slowly and progress over time, becoming severe enough to interfere with daily tasks. People with Alzheimer’s lose the ability to be able to keep up a conversation because their memory will fail. They also will become angry because they don’t understand why they cannot remember what just happened 10 minutes ago. On average after being diagnosed with Alzheimer’s people live 4-20 years, but a large amount end up passing a way around 8 years later. Nobody knows what causes Alzheimer’s or what can cure it as we are still trying to figure out a cure. We do know that Alzheimer’s kills and damages the nerve cells of the brain and causes it not to function properly. Alzheimer’s cannot be fully diagnosed until after death as you have to physically look at the brain itself. This being said I would not take part in being tested to see if I would develop Alzheimer’s because I would not want to know that I was going to end up living the end of my life not being able to remember what I had for breakfast that day or not being able to remember my own children and family members. I feel for all my tenants that have Alzheimer’s,......
