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

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

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

1. Explain why a layered security strategy helps mitigate risk and threats both external and internal. Multiple layers can be used to secure internal threats like keeping employees from accessing inappropriate material‚ update and patch workstations and run current anti-virus/malware on workstations daily. The layers also help mitigate external threats like hackers by using firewalls and shutting traffic out of the internal network. 2. Why is it a good idea to put shared servers and services on

Saliva Lab Since the amylase enzyme is present in saliva‚ starch digestion begins in the mouth. Salivary amylase changes the polysaccharide starch into many disaccharide molecules of maltase (a simple sugar) which are further broken down into glucose units by maltase enzyme in the As stated above‚ saliva contains the amylase enzyme which begins the breakdown of starches. The efficiency of starch digestion by amylase can be measured by how much simple sugar it produces under

The protein concentration in bovine cells was measured by diluting the homogenate with a 1:5 ratio; 50 microliters of homogenate and 200 microliters of water. Then 5 known protein concentration samples which were 0.4‚ 0.8‚ 1.2‚ 1.6‚ 2.0 mg/ml of bovine serum were used to

Bio 6 (Mon. Lab) 5/6/13 The Effects of Pepsin VS. Trypsin in The Digestion of Protein Introduction As food is mechanically and chemically digested through our oral cavity then passes through our pharynx and down our esophagus‚ our food then enters the stomach. The stomach‚ being the main organ for storage‚ also helps with breaking down our food‚ but in order to accomplish that our pancreas helps by excreting an inactive digestive enzyme called pepsinogen. Pepsinogen is the inactive form
