BIOMAGNIFICATION LAB REPORT AIM The aim of this lab is to model bioaccumulation and biomagnification through a food chain. MATERIALS 100 M&M’s Paper towel to lay M&M’s on 20 small cups labelled “zooplankton” 5 medium cups labelled “minnow” 2 larger cups - one labelled “eel #1”‚ and another labelled “eel #2” 1 bowl labelled “osprey” PROCEDURE The pile of M&M’s represents the phytoplankton population in a lake. The printed “M” on the candy represents the amount of DDT (in ppm)

Lab 4: Le Chatelier’s Principle Name: Cammey Mahowald Lab Partners: None Date of Experiment: March 16‚ 2015 Course: CHE 112 Abstract: The purpose of this experiment is to understand the components of a reaction at chemical equilibrium and use Le Chatelier’s principle to predict the direction an equilibrium position will shift upon changes in the concentration‚ temperature‚ and pressure. It was determined that in the equilibrium of chromate and dichromate it is an exothermic reaction and in the

LabVIEW (Laboratory Virtual Instrument Engineering Workbench)‚ created by National Instruments is a graphical programming language that uses icons instead of lines of text to create applications. A LabVIEW program consists of one or more virtual instruments (VIs)‚ Virtual instruments are called such because their appearance and operation often imitate actual physical instruments. The objective of developing a virtual interface that acquires data from physical instrument (pH probe) used in the monitoring

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

Lab 4: Endocrine System Physiology | 1. | | Refer to Activity 1: Determining Baseline Metabolic Rates. How did the baseline metabolic rates of the three rats differ? Answer: | The metabolic rates for the thyroidectomized and hypophysectomized rats were lower than that of the normal rat. | | | 2. | | Why did the metabolic rates differ? Check all that apply: Answers: | The hypophysectomized rat lacked thyroid-stimulating hormone. The thyroidectomized rat lacked thyroxine hormone.

I lab Week 4 Exercise 1 As most countries in the Asian and Pacific region‚ contemporary Mongolia is undergoing mobility transitions. Mongolia is in the midst of its demographic transitions and has pursued model of economic growth that has been more focused on import-substitution. In other hand‚ Mongolia is in demographic transition‚ witnessing a moderate‚ but decreasing‚ population growth‚ sustained decline in fertility and a steep increase in the number of young adults entering the labor market
