The body system that directly provides for this demand is the circulatory system. When you exercise, the circulatory and muscle system cooperate, in order to meet the increased needs for strength and energy.

A strand of DNA having base sequence as ATG CGA. The complementary strand of DNA will be produced with base sequence as TAC GCT. In the double strand DNA nitrogenous bases paired in a specific manner, A (Adenine) always pair with T (Thymine) with double hydrogen bond or vice-versa and C (Cytosine) pair with G (guanine) with triple hydrogen bond or vice-versa.
