One molecule of affibodyreversibly binds to one molecule of bap1 to form an affibody-bap1complex. you add 75pmoles of affibodyand 20pmoles of bap1 to a test tube with 3ml total volume. 36hours later, you measure the amount of affibody—bap1complex to be 4pmoles. a. assuming an association rate constant of 2x105m-1s-1, calculate the dissociation rate constant. b.how much additional affibodywould need to be added to achieve 10 pmoles of affibody—bap1complex at equilibrium? assume the affibodysource is highly concentrated such that you can neglect the change in volume upon affibodyaddition. c.recalculate the solution to part bif the affibodysource is present at500 nm, so that you cannot neglect changes in volume upon addition. what was the % error in part b?

Which position represents spring in the southern hemisphere? a) b) c) d)

1) which of the following is the best example of a physical change? a) sugar dissolving in tea b) firefly glowing 2) in the combustion of ethane, what is/are the reactants? c2h6 + o2 ==> co2 + h2o a) c2h6 and o2 b) co2 and c2h6

98 points you will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven. what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forces choose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart. choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.
