Answer:helps you and other scientists out
Explanation:
<h3>now that your done with your lab you need a report that has a graph that explains how it worked and you need a conclusion on if your hypothesis true of false, and how you can do better in another experiment. but before you write down your conclusion make sure you run the experiment multiple times for accurate results </h3>
trees do not fix N2 from air they fix oxygen with the help of N2 fixing bacteria . so trees do not fix N2
Answer:
10%
Explanation:
Chargaff postulated the complementary base pairing rule, where he stated that in the DNA molecule, Adenine (A) will always pair with Thymine (T) and Guanine (G) with Cytosine (C) i.e. A-T, G-C
Chargaff stated that the concentration of purines (Adenine and Guanine) is always equal to that of pyrimidines (Thymine and Cytosine) i.e. {A} + {G} = {C} + {T}
These equal concentration equals 100% in totality i.e. A+G+C+T= 100%
Thymine pairs with Adenine, if there is 40% of Thymine in the DNA molecule, it means there will be 40% of Adenine also. 40 + 40 = 80%. This leaves us with 100-80 = 20% for Guanine and Cytosine.
Since there will be an equal amount of Guanine and Cytosine too, Guanine will therefore, be 20/2 = 10%.
That is, 10% Guanine, 10% Cytosine.
