2. Arrange these organisms into a food web:
Serjik [45]

Explanation:

A food web shows how organisms in a community prey and feed on each other (feeding relationships). It is composed of many interconnected food chains. In addition, it, therefore, shows how energy is transferred up an ecosystem from the primary producers (in this case the trees and grass) to the tertiary consumers (in this case the hawks and wolves).

Chargaff's Rule. If there is 20% Adenine in the cell, what is the percentage of Thymine, Guanine, and Cytosine found in the same
Ulleksa [173]

Answer:

A= 20%

G= 30%

T= 20%

C= 30%

Explanation:

Recall that the sum of all nitrogenous bases in the DNA nucleotide is equal to 100%. And specific base pairings of Adenine to Thymine (A=T), and Cytosine to Guanine (C=G) must be equal.

So, the percentage of Adenine equal thymine, and that of cytosine equals guanine.

Now, A + T + C + G = 100%

So, if Adenine makes up 20% of the DNA nucleotides, Thymine is also 20%.

Then, 20% + 20% + C + G = 100%

40% + C + G = 100%

C + G = 100% - 40% = 60%

So, divide 60% by 2 to obtain the individual percentage of cytosine and guanine. Each will take 30%

Finally, A= 20%; G= 30%; T= 20%; C= 30%
