You perform a ligation with ncoi/noti-digested, pet-41a vector and the egfp insert from pegfp-n1 (as in lab). you then transform the ligation mix into e. coli and plate on lb medium containing kanamycin. consider the following unexpected outcomes, and suggest controls: nothing grows. what controls might you design to determine whether the e. coli cells are viable (alive) versus whether the e. coli is competent? what would the results of those controls be? you see lots of growth, but when you isolate plasmid from numerous e. coli colonies, all you find is pet-41a with no insert. suggest the most likely way these colonies arose (aside from contamination). what would the results of your controls look like if your suspicion was correct?

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

girl imma just put my comment here because i need a couple point okurrttt

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
