BIO 111 TAMU lab exam 1 latest 2023 with certified solutions Accuracy a measure of how close a result matches a correct or standard value. For example, how close a dart is to the bullseye in a dartboard is an indicator of accuracy. Precision a measure of variability. For example, three darts placed close together on a dartboard indicate high precision, but if this cluster of darts is far from the bullseye it would also indicate low accuracy. an ideal experiment yields results with both high ac...

TAMU Bio 111 Lab Exam Questions With Verified Answers What is a blank? A blank is used to 0 (zero) the spectrophotometer. The blank includes everything in your experimental samples except what you want to measure. What does Coomassie (Bradford reagent) bind to? peptide backbone of a protein What colors does it change when bound or unbound? blue when bound, and reddish-brown when unbound When looking at the Bradford assay, how can you visually tell that there are more/less proteins ...

What is the difference between ubiquinone (Q) and ubiquinol (QH2) - Q is fully oxidized so it has no electrons, QH2 is fully reduced so it has 2 more electrons and H+ than Q What are the other sequentially acting electron carriers in the respiratory chain besides NAD and flavoproteins - Hydrophobic quinone (ubiquinone, Q), Cytochrome (contain iron), Iron-sulfur proteins What is the final stage of cellular respiration and where does it happen - Oxidative phosphorylation, in the mitochondria...

Which design would be best for her experiment? A.1 plant of the sun variety tested under blue light only, and 1 plant of the shade variety tested under blue light only. B.4 plants of the sun variety: 1 tested under blue light, 1 under green, 1 under red, and 1 under yellow light, and 4 plants of the sh...

What is the basic unit of all life? Cells All cells must share the features that enable them to what? Perform the functions necessary for life. Robert Hooke Discovered the calls while looking at cork under his microscope. Antoni van Leeuwenhoek First to describe living cells Larger Cells Need more proteins (energy cost) Smaller Cells Can absorb more because their is more surface area to volume Can maintain small size, within itself Two Tenets of the Cell theory 1. All living organi...

Rearrange the following equation to solve for P. (P+a)(V-b)=nRT - Answer- P=(nRT/V-b) -a What is the slope if B is plotted on y-axis and A is plotted on x-axis? 5A + 3B = 8 - Answer- -5/3 In an experiemnt, the best-fit-line equation between Absorbance (A, unitless) and concentration (c, mg/mL) is used to calculate the concentration of Fe. Based on the best-fit line equation given below, what is the concentration of Fe if the absorbance is 1.25? A = 851 c + 0.03 - Answer- 0.0014 ...
