Page 1 of 4 Name:   Alireza Ghoorchian Lab Worksheet 1 SCI214 – Integrated Science Lab 1: Biotechnology  – Control groups, and independent and dependent variables. Instructions At least three experiments must be  conducted using an appropriate  experimental design.   Each experiment should be repeated  three times  under   no low and high infestation conditions, and the average taken for  the values (sum of observations/3).  Record your data on the data table  below and answer the lab questions.   This lab exercise/worksheet is  valued at a maximum of 40 points. Prelab Questions (2 points each) Answer the following four questions with as much detail as possible by entering your response in  the box below the question. Please complete these questions before conducting the experiment. Question 1:   What is the European Cork Borer and why would farmers be concerned if any were present  in their corn fields? Response to Question 1   The European Corn Borer (Ostrinia nubilalis) is a pest of grain, particularly maize . The insect is native to Europe originally infesting varieties of millet including broom corn . Because of the effect that some products have on the environment and also the lost of corn can be very expensive. Question 2:   Bacillus thuringiensis   is a bacterium that produces a crystalline poison that is deadly to  certain insects.  What is the name of the gene that codes for the protein and how have geneticists used  this information to combat infestations caused by this insect? Response to Question 2  It’s called  Cry9Ca1. Seed companies are now marketing Bt corn, one of the first tangible fruits of biotechnology that has practical implications for U.S. and Canadian corn farmers. Bt corn hybrids produce an insecticidal protein derived from the bacterium Bacillus thuringiensis,
