Human Digestion Christine Wilkes SCI 241 Natalia Woehl March 8‚ 2011 The human digestion system consists of a series of organs and glads that process the food that we eat. The digestion process starts when food enters the mouth‚ then with the chewing of food. The salivary glads help break down the food with enzymes so that it is easier to swallow. While the food is being chewed it is turned into bolos‚ which then travels down the pharynx and through the esophagus. The esophagus is the long

Lab Report: Purpose: The Objective of this lab was to learn how to measure the pH (or acidity) of commonly known fluids‚ using the correct tools and procedures. To then use that data to document the changes noticed when mixing those same fluids and changing their respective pH levels. Materials: In order to conduct this experiment several pieces of equipment and other materials were needed. The first item was a graduated cylinder‚ which was used in order to measure out the precise

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

The psychodynamic theory: It is based around three dynamic which are Food‚ Sex and water. This approach is based on the premise that human behaviour and relationships are shaped by conscious and unconscious influences. This was developed by Freud Sigmund. Conscious: consists of all the mental processes of which we are aware and what you want. For example‚ you may be feeling thirsty at this moment and decide to get a drink. Unconscious: this contains our biological based instincts for the original

PHYSICAL DEVELOPMENT 0 – 3 Years. Physical development at this stage is usually very rapid. From the day babies are born they have a huge dependency on their body’s reflexes for movements this is important as this enables them to feed or grasp whenever they touch something. By time they reach the age of one‚ babies have much more control over their bodies‚ as they are now beginning to become more independent by trying to crawl‚ shuffle‚ pulling or pushing on things to stand etc. depending on their

Nahom Assefa CHM-201 General Chemistry and Laboratory I Laboratory 8. Spectroscopy Purpose: Spectroscopy is the study of matter interacting with electro-magnetic radiation (e.g. Light). In this lab‚ we will separate some light sources in to constituent colors and find out the wavelength of some atomic emissions. We will also try to compare the line spectra found from gas discharge tubes and flame emissions. Finally‚ we will measure

Introduction: With the execution of this experiment‚ we began to go deeper into the Cell and Molecular Biology course. The main focus of the experiment would be how the Restriction Endonucleases cleave the strands of DNA. For this experiment‚ pBR322 was the specimen to use. Restriction Endonucleases work by cleaving the sugar phosphate backbone of specific DNA sites. Restriction enzymes that have been isolated from bacteria have a defensive role. This idea is illustrated when an attacking foreign
