...1. Name: Leeann Salas 2. Grade: 11th (Junior) 3. Why did you register to take AP Biology? I took AP Biology to help me narrow down my college major options (genetics, biology, or medical) and to learn more about the environment. In particular, I am interested in the effects of GMOs on the health of the human body and comparisons between the roles of GMOs and their natural counterparts in a wild ecosystem. 4. What are your personal strengths when it comes to learning new material? How do you learn best? My personal strengths are writing and researching; therefore, I use writing repetition to help me memorize definitions and words. (If I’m confused by something or if I become interested in a subject, I like to look things up on my own online.) Usually, I enjoy using Quizlet.com to help quiz myself on class material. My favorite note-style to use is the Cornell Note method because of its simplicity. For the most part, I memorize things easily. Any in class repetition or brief warm-ups before class are fantastic for me to have....

...Cells, Exchange and Transport Cell Structure State the resolution and magnification that can be achieved by a light microscope, a transmission electron microscope and a scanning electron microscope; | Light microscope | TEM | SEM | Resolution | 200nm | 0.1nm | 0.1nm | Magnification | X1500 | X250 000 | X100 000 | Explain the difference between magnification and resolution; Magnification: How much bigger the image is than the specimen. Resolution: How detailed the image is and how well a microscope can distinguish between two different points. Explain the need for staining samples for use in light microscopy and electron microscopy; Objects need to be stained because they can sometimes be viewed as completely transparent under a microscope. The stain is taken up by some parts more than others and the contrast makes the different parts show up darker than others. Calculate the linear magnification of an image; Magnification = length of image/ length of specimen Describe and interpret drawings and photographs of eukaryotic cells as seen under an electron microscope and be able to recognise the following structures: nucleus, nucleolus, nuclear envelope, rough and smooth endoplasmic reticulum (ER), Golgi apparatus, ribosomes, mitochondria, lysosomes, chloroplasts, plasma (cell surface) membrane, centrioles, flagella and cilia; Nucleus: Large organelle Nucleolus: spherical structure inside...

...Treating Pea Plants with different concentrations of Potassium Acetate Potassium acetate can be prepared by treating a potassium-containing base such as potassium hydroxide or potassium carbonate with acetic acid through the following reaction: CH3COOH + KOH → CH3CO2K + H2O. We choose potassium acetate to treat our plants with, for several reasons. First of all, this salt is totally soluble in water through following reaction: KCH3COO (s) → K+ (aq) + CH3COO- (aq). Also, potassium acetate is used as a catalyst in the production of polyurethanes. Potassium acetate can be used as a deicer instead of chloride salts such as calcium chloride or magnesium chloride. It offers the advantage of being less aggressive on soils and much less corrosive, and for this reason is preferred for airport runways. It is, however, more expensive. Potassium acetate is also the extinguishing agent used in class K fire extinguishers because of its ability to cool and form a crust over burning oils. Moreover, Potassium is found in low concentration in plasma and extracellular fluids. It is the chief cation of body cells, and is concerned with the maintenance of the body fluid composition and electrolyte balance. The major amount of potassium is excreted in the urine. Therefore, the kidney normally determines potassium balance. The acetate ion is completely metabolized in the body, providing a source of hydrogen ion acceptors. Therefore, according to all of the reasons above and so much more, we choose...

...“Biology Article” Yolanda Haskins Professor Lynn Roginsky Introduction to Biology May 9, 2013 A New System for Cancer Detection This article summarizes a new technique that would allow for cancer cell detection without being invasive to a person’s body. It states that currently, human cancer cell detection is conducted through a person being cut on or biopsied. This new procedure allows for humans bodily fluids to be utilized in detecting cancer cells. P.Chandra states, “While current cancer-diagnosis methods rely on an invasive biopsy” to relay that many may not feel the need or desire to undergo biopsy, a type of simplistic surgery, for cancer cell detection. This article relates to this course by the basic information I learned about the plasma membrane known as cell membranes. Cell membranes are lipid bilayers that consist mainly of phospholipids. However, when it comes to cancer cell membranes they tend to have more anionic lipids than normal cells. Our course text in Chapter 3 talks about the “Cell Structure” and gives us the break down on “What, Exactly is a cell? The Structure of Cell Membranes, Introduction of Prokaryotic Cells, etc.”. This article does not provide enough background information to help me understand this article. In my opinion, I would have like to read more about the differences between the normal cells and cancer cell membranes and how they are made up. This article caught my attention due to my family member surviving stage four...

...Kitch 1 Tristan Kitch Mrs. Hayden IB Biology HL 2 8 September 2014 An Investigation of the Effect of Wavelength on Photosynthesis DESIGN: Research Question: The purpose of this lab is to determine how the wavelength of light that alfalfa sprouts are exposed to affects the rate of photosynthesis in those plants. Hypothesis: Photosynthesis will occur at the highest frequency when the alfalfa plants are exposed to blue light (475 nm) ("What Wavelength Goes With a Color?"). The second highest amount of photosynthesis will occur when the alfalfa plants are exposed to red light (650 nm) ("What Wavelength Goes With a Color?"), and the lowest amount of photosynthesis will occur when the alfalfa plants are exposed to green light (510 nm) ("What Wavelength Goes With a Color?"). This is because the pigments in the plants’ chloroplasts, such as chlorophyll a, chlorophyll b, and carotenoids, absorb the most light in the blue color range, the second most light (of the selected colors) in the red range, and the least amount of light in the green range (see Figure 1). Kitch 2 Figure 1: Amount of Light Absorbed by Chloroplast Pigments Chlorophyll a absorbs the most light in the blue to indigo and red to orange ranges, chlorophyll b absorbs the most light in the blue and orange ranges, and carotenoids absorb the most light in the blue to blue-green range (“Absorption Spectrum”). Background: Originally, an experiment was run using chloroplast solutions rather than alfalfa...

...even the lack of the smallest organism could tamper the ecosystem just like a spring toy that does not work properly if the spring is slightly bent. After Grade 10, I took up pure sciences- Biology, Physics and Chemistry as well as Mathematics and English. My passion for biology was keenly supported by all my chosen subjects. Chemistry helped me understand the molecular structures while Physics and Mathematics helped me understand the dynamics and statistics that we were provided with. Being an avid reader, has led to the formation of many ideas which I feel can be expressed on gaining more insight. A degree in Biological Sciences will help me reach my dream. Earlier this year, three of my friends and I participated in NTU Science Symposium. We had to write a research paper in any field of science. The four of us love biology and felt that we would be able to express our skills and knowledge through the paper and came up with the topic 'External Factors Affecting Bacterial Growth'. The research paper certainly tested our abilities to work as a team. We had to submit the paper in May and all of us had many other commitments apart from the research paper. Like every group has someone to keep all the interpersonal relations intact, this task was an added responsibility to me. The research paper helped us understand as well as apply many of the already learnt concepts. I realised the importance of understanding and applying the knowledge procured during theory classes. In12th grade...

...subsequently, the invention of the internet, the science community particularly has had a drastic shift in the scientific publication process. Journals that took months to publish, print and be delivered, are now instantly made available through online websites. Moreover, modernizing resources results in the increase in the available, accessible information for the community. Since the beginning of the century, online science journals have made the scientific community cohesive by providing with the most up to date findings for research being conducted in particular fields as well as all are new ways to “interact” amongst individuals. For this report we have chosen four online resources that provide information on the area of biomolecular biology and neurology, we will enumerate their usefulness to our particular field of interest and their incidence in our future professional careers. In the 1850’s, an Austrian monk Gregor Mendel discovered that he can manipulate plant offspring to breed plants selectively with traits that he wished to see; he cross-bred two tall pea plants and found that the offspring almost certainly expressed the "tall" feature. At the time, the scientific community was ignorant with genetic and DNA comprehension, but Mendel's work would prove to be a precursor to Darwin's evolutionary theory and eventually a foundation for all medical practice performed today. While our understanding of genetics is superb at best, new ideas and practices keep the medical...

...What is a Microbiologist? If you become a microbiologist, you may isolate organism cultures and classify the types of organisms found in soil, water and living hosts. You might also observe how organisms interact with each other and with living plant and animal tissue, as well as analyze the relationship between organisms and disease. Some of your duties could include preparing technical reports and research papers detailing your findings and making recommendations based on your research. You might also supervise lab workers and technicians and perform lab experiments for government health departments and physicians. A microbiologist is a scientist who studies the properties of fungi, algae, bacteria and other microscopic organisms. Areas of specialization include virology, immunology or bioinformatics. The following chart provides an overview about this career. Degree Required Bachelor's degree Field of Study Microbiology, biochemistry or cell biology BS Biology is the course needed to take Microbiology.

...Biology From Wikipedia, the free encyclopedia For other uses, see Biology (disambiguation). Biology deals with the study of the many varieties of living organisms. Clockwise from top left: Salmonella typhimurium, Phascolarctos cinereus, Athyrium filix-femina, Amanita muscaria, Agalychnis callidryas, and Brachypelma smithi Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy.[1] Biology is a vast subject containing many subdivisions, topics, and disciplines. Among the most important topics are five unifying principles that can be said to be the fundamental axioms of modern biology:[2] 1. Cells are the basic unit of life 2. New species and inherited traits are the product of evolution 3. Genes are the basic unit of heredity 4. An organism regulates its internal environment to maintain a stable and constant condition 5. Living organisms consume and transform energy. Subdisciplines of biology are recognized on the basis of the scale at which organisms are studied and the methods used to study them: biochemistry examines the rudimentary chemistry of life; molecular biology studies the complex interactions of systems of biological molecules; cellular biology examines the basic building block of all life, the cell; physiology examines the physical and chemical functions of the tissues, organs, and organ systems of an organism; and ecology...
