The directions for a laboratory activity call for 50 ml of solution A. A student accidentally takes 55ml from the stock bottle. What should the student do with the extra 5 ml of solution A? a-Return the extra 5ml to the stock bottle and replace the cap.
b-pour the extra 5 ml down the drain and rinse the sink with cold water
c-dilute the extra 5 ml with 100 ml of water and pour it down the drain
d-set the extra 5 ml aside in a labeled beaker and ask the teacher for advice

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

just go with your heart buddy

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.
