Every DNA strand has an EQUAL number of adenine and thymine nucleotides in a molecule. Explain why. Is this true for cytosine and guanine nucleotides? Explain your answer.

Is this true for cytosine and adenine nucleotides? Explain your answer.

In other words, adenine and thymine are complementary base pairs, and cytosine and guanine are also complementary base pairs. This is the basis for Chargaff's rule; because of their complementarity, there is as much adenine as thymine in a DNA molecule and as much guanine as cytosine.

Explanation:

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
