    Bio Lab homework: Water Parameter Identification Chart

    For question 1, your answer of G tank having the lowest PPM of O2 is correct. For question 3, the tank with a reading out of line with expected PH is B. According to the chart, it should have a higher PH with Plant and Fish with Light, but instead it decreased. This is most likely due to a...

    Turning glutamate into ribose-5-phosphate

    Your approach is correct, but there are a few things to consider. First, you mentioned using 5 pyruvates for neoglucogenesis, but this only yields 1 fructose-6-P and 1 glyceraldehyde-3-P. So you would need a total of 10 pyruvates to get 2 fructose-6-P and 2 glyceraldehyde-3-P for the pentose...

    Blood Group Substance A: Examining Terminal Sugars

    Can anyone please clarify this for me? Hi there, Thank you for bringing this up! The correct answer is actually option 1, N-acetylgalactosamine. This is because in blood group substance A, the terminal sugar is attached to the galactose molecule through an N-glycosidic bond, meaning it is...

    Using Airy's Model of isostatic equilibrium, solve for....

    You are correct that you need the density of the mantle to solve for the average anti-root height. However, you can still solve for the density of the mantle using the given information and Airy's Model of isostatic equilibrium. Here is a step-by-step guide to solving this problem: 1. Start by...
