1. B Polio
2. B DNA

I know number one FOR SURE!!

These are simple questions you would find easily in your text. Instead of gropeing around on the internet finding others to do your homework try doing it yourself.
1 learn who Salk and Sabin are....for C....ts sakes you probablyhave taken one or the other.
2 is also rather obvious....just read the question a few more times
3 once again READ THE QUESTION or better read the text book!

Those aren't your questions -- those are your homework questions reposted here with a demand for people to do your homework for you. To find the answers, you need only use the resource that is right there at your fingertips -- the internet and your text book should provide the answers you seek. I recommend google if you need a good search engine.

#1 is A - they contributed to the polio vaccine

#2 is B DNA for sure

#3 is A CAT scans
