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.
The name for the total amount of living matter is biomass. Hopefully this helps :)
The generation of electricity through nuclear energy reduces the amount of energy generated from fossil fuels. Less use of fossil fuels means lowering greenhouse gas emissions and others.
Answer:
C
Explanation:
For productivity to increase, it require an increase in the input which has to be directly proportional to an increase in the output
Answer:
protons is 7 neutrons should be 9
Explanation:
protons number is its atomic number
the number of protons and the number of neutrons determine an element's mass number.
