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

digestive system Tongue • For taste • Pushing food into the esophagus Papillae • Rough edges of that tongue that contain the taste buds Hard and soft palate • Separate the nasopharynx from the mouth Parotid gland • Secretes saliva (amylase enzyme) which breaks down starches into sugar Stomach • Stores food • Begins digestion of tissues and proteins by secretion of gastric juices. These juices are very acidic (pH 1-2). The semi-digested stomach contents are called chyme Esophagus

An investigation into the effects of temperature on enzyme action An enzyme is a biological catalyst that speeds up the rate of reaction in certain biological functions. They play a vital role in many aspects of human physiology and are necessary for the functioning of a number of systems‚ for example in the digestive system to help to break down food. All enzymes have a unique active site that can fit on to a particular molecular arrangement on a target substrate; a substance e.g. carbohydrate

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

Planaria Regeneration in Ideal Temperatures vs. Cold Temperatures Christina Malfas Abstract Planaria are flatworms that live in quiet freshwater bodies. They live in a narrow range of temperatures‚ from 22-24°C. They regenerate asexually‚ specifically through a process called epimorphosis‚ in which they completely regenerate one half of their bodies after splitting themselves in two. The diffusion gradient model assumes that cells in an organism “know” their orientation on that organism due

Conclusion We therefore conclude that our program will solve the problems regarding to the UAM (Uniform Accelerated Motion). This will got to be a help in studying Physics because it’s an easy way to solve problems regarding the topic that we’ve said earlier. This program didn’t aim to teach the students to be lazy and not to study at all but our program aims to help the students to simply solve the problems given. Recommendations More knowledge should be given to us to make
