Answer:
C) The amount of A is always equivalent to T, and C to G
Explanation:
Chargaff's rule was given by the Austrian chemist, Erwin Chargaff in late 1940s. It explains the composition of the four bases i.e. Adenine(A), Guanine(G), Thymine(T) and Cytosine(C) in a DNA molecule. According to it, purine and pyrimidine bases are always found in 1:1 ratio in a DNA molecule. A and G are purine and T and C are pyrimidine bases and a purine always forms a pair with pyrimidine base hence the amount of A will always be equal to T and amount of G will always be equal to C. This rule forms the basis for the Watson and Crick pairs in DNA double helix model.
Behavioral isolation. This is when animals that can otherwise mate do not mate because of differences in courtship behavior. These animals choose to mate with animals of their own species.
Deoxyribose is the sugar that is found in a nucleotide.
It declines. Members above will die off due to starvation, and members immediately below will proliferate and kill off (through predation) the members below themselves.
The answer that you would like to put is:
The force between charges decreases as the distance between them increases. Like charges repel each other. Oppostite charges attract each other
