Suppose you inoculate 3 flasks of minimal media broth with E. coli. Flask A contains glucose. Flask B contains arabinose. Flask C contains glucose and arabinose. None of the flasks contain any other carbon sources. Each carbon source was added in large enough amounts to sustain growth for at least a day. After a few hours of incubation you test the flask for the presence of an enzyme encoded by the arabinose operon we studied in class (araBAD). Which flask(s) of bacteria do you predict will have this enzyme in high amounts

What is unique about the members of the group of fungi to which penicillium notatum belongs? they are not important for medicine. they are not made up of hyphae. they are used in fermentation. they lost the reproductive phase.

Which type of scientific statement is defined as a hypothesis or group of hypotheses that can be accepted as true based on the repeated experimentation with similar results

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.
