Shannon Yeh October 28‚ 2013 Animal Dentition Laboratory Assignment (Figure 1.) Tooth Sharpness (degrees) (Figure 2.) Relative Tooth Width (mm.) Results: The dental formula is a convention used by mammalogists to determine the tooth number and tooth arrangements. The dental formula is calculated by counting the number of incisors‚ canines‚ premolars‚ and molars present in the upper jaw (one side) and counting the number of incisors‚ canines‚ premolars‚ and molars

that may expose you to splashes or sprays of blood or body fluids 2. Why should you consider a body fluid capable of infecting you with disease? o I think you should be aware and alert because its precaution to practice when youre working in a lab setting. 3. Describe how to dispose of waste material contaminated with body fluids. o You should dispose all waste material in the correct disposal area‚ and you can throw away the waste materials in the biohazard container. 4.

Snakes are absent 18. Yes 19. No 20. B 21. Experimental Study 22. Field Study 23. Paint the same colors in a non-ringed pattern 24. Less ringed replicas would be attacked‚ because the milk snakes would become more of a prey 25. You could do a lab experiment on the snake attacks and change what the models look like. Such as ring size or color combination to see what they attack more or less.

Photosynthesis Lab Kozlowski Kendal Schweiss Hour 6 Introduction: Photosynthesis is carbohydrate production using light and chlorophyll. It is a process when green plants and other organisms turn carbon dioxide and water into carbohydrates and oxygen‚ using light energy trapped by chlorophyll. The rate of photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. 2H2O + CO2 + light -> carbohydrate (CH2O) + O2 + H2O There is a spongy mesophyll

Chemistry Lab Write-Up Title: Paper Chromatography of Powdered Beverage Mix Purpose/Objective: The purpose is to be able to use liquid chromatography to separate dyes in a powdered beverage mix‚ calculate the Rf values for each dye‚ and rank the polarity of each dye present. Hypothesis: If we are to use the liquid chromatography to investigate the different dyes‚ then I think the different dyes will come up having different polarities and Rf values. Procedure/Method: Draw a line across

Egg-speriment Write-up Part 1- Purpose: Why did we do the experiment? The purpose of this experiment was to understand how osmosis works and that the cell membrane is selectively permeable. Osmosis is the diffusion of water molecules through a selectively permeable membrane. Many cells cannot function without adequate water‚ so cells depend on osmosis. When a cell is selectively permeable‚ it means some substances can pass through while others can’t. Many examples of these were shown throughout

minutes) the root tip will feel soft when touched with a mounted needle (Do not let it dry out completely). * Heat it in order to speed up the process of the cell wall breaking down‚ and also for the stain to spread quicker. The stain will bind with the DNA‚ and it will become more visible. 4. Now‚ using forceps or the mounted needle‚ pick up the softened root tip and transfer it in to a

Jordan Alyce Norris November 7‚ 2014 Biology 111-J3 Predicting Patterns of Inheritance Using Monohybrid and Dihybrid Crosses Introduction This experiment was on Mendelian Inheritance; which is the inheritance of biological features that are based on the rules proposed my Mendel. The purpose of this experiment was to show how to predict patterns of inheritance by using Punnett Squares to perform monohybrid and dihybrid crosses. Two crosses were performed. Cross one consisted of heterozygous alleles
