Leanne Butler 02-12-09 Anatomy and Physiology Introduction to the Human body Introduction The human body is such an interesting machine‚ the way it is structured and how it works is educational. There is so much to learn about the human body and up until today scientists are still under going medical research. There are a lot of questions people would like to know about how their body works. The report will include

CORE PRACTICAL ONE Describe how the effect of caffeine on heart rate in Daphnia can be investigated practically‚ and discuss whether there are ethical issues in the use of invertebrates. Daphnia‚ the water flea‚ is a small freshwater crustacean which lacks physiological methods of maintaining a constant body temperature. This means that if the environmental temperature changes‚ its body temperature does so too and its metabolic rate will be expected to rise or fall accordingly. So the temperature

Sept 27‚ 2010 Chapter 4 * With four valence electrons‚ carbon can form four covalent bonds with a variety of atoms * This tetra valence makes large‚ complex molecules possible * Fundamental groups: Alkanes and Alkenes * The electron configuration of carbon gives it covalent compatibility with many different elements * The valences of carbon and its most frequent partners (hydrogen‚ oxygen‚ and nitrogen) are the “building code” that governs the architecture of living

CHAPTER 2: CELLS Learning about disease is often simplified by growing it in a dish – some cells like heart and nerve cells however do not grow easily outside the body. Cellular reprogramming takes cell back to a state similar to stem cells and then coaxes them to specialize in a different way. Example – LEOPARD syndrome MIM 151100. Acronym for symptoms: enlarged heart w/blocked valves to the lungs‚ freckles‚ abnormal genitals‚ deafness. Skin cells taken from patients were reprogrammed to give

Big Idea 2 Biological systems utilize free energy and molecular building blocks to grow‚ to reproduce and to maintain dynamic homeostasis. Living systems require both free energy and matter to maintain order‚ grow and reproduce. Organisms employ various strategies to capture‚ use and store free energy and other vital resources. Energy deficiencies are not only detrimental to individual organisms; they also can cause disruptions at the population and ecosystem levels. Biological systems must both
