Answer:
2 significant figures
Good luck with your work! :)
Answer:
For this experiment we are going to take plate 1 as the control plate, so, in it there will be just E. coli in LB/agar; in plate 2, we are going to put E. coli in LB/agar and some ampicillin. Then, we have to wait for the E. coli colonies to form. After a while, the E. coli growth can be compared on both plates and determine if ampicillin affects or not the E. coli colonies.
Explanation:
If the ampicillin affects negatively E. coli colonies, we are going to observe that in plate 1 (control plate) there are E. coli colonies growing, but in plate 2, there is no E. coli colonies or, at least, there is a fewer number of colonies on it. If ampicillin doesn't affect E.coli, plate 1 (control) and plate 2 (ampicillin experiment) are going to be similar in number of colonies.
b. atomic radius
as it goes increases when it goes down the periodic table, it decreases when going left to right. all the others decrease while going down the table.
if it helps you to remember, everything here besides atomic radius has an e in it. and if you make a connection with it to electrons, they are negative, which means they would decrease going down the table. so e=decrease while going down
thats what helped me remember it, so i hope this technique could help you too.
