Question 12 worth 9 points An ice-cream shop sells only ice-cream sodas and milk shakes. It puts: 1 ounce of syrup and 4 ounces of ice-cream in an ice-cream soda 1 ounce of syrup and 3 ounces of ice-cream in a milk shake   If the store used 160 ounces of syrup and 512 ounces of ice-cream, how many ice-cream sodas and milk shakes did it sell? a)  Set up the system of equations, letting: x = # ice-cream sodas sold y = # milk shakes sold   b)  Solve the system (show your work and justify your answer).  

Question 6 worth  8 points Let :

Of the choices below, which is the best way to contact your instructor.

For this question on genetically modified organisms, please pick ONLY ONE of the following questions to answer. I.e., you have a choice of which you would prefer to answer, so pick the one you’re more comfortable with. Please do not answer them all as I will only grade the first (and hopefully only!) one you answer! Please use full & complete sentences in your answer –   Option #1: Describe the process of using a bacterial plasmid in genetic engineering. Clearly explain the steps that would be needed to create a GMO.                                                                                     —or— Option #2: What information we can provide to our friends and family about GMOs who may be concerned about their effect on the environment and risks of use? Provide at least 2 truths about GMOs                                                                                     —or— Option #3: In the pGLO transformation experiment, E. coli is given a gene from a jellyfish that allows it to produce green fluorescent protein (GFP). How is it possible for E. coli, a prokaryote, to produce a functional protein that is normally made by a eukaryotic organism? What insight does this give us about the processes of transcription and translation across domains?  Explain your answer. Copyright 2025 by Edmonds College Department of Biology. All rights reserved.

Imagine a cell experiences an deletion mutation involving the removal of one or more nucleotides from the sequence of a gene in its chromosome. Which of the following deletion mutations would most likely have the greatest impact on the cell, i.e., change the structure (and thus function) of the resulting protein the most?
