Truly modern molecular biology emerged with the uncovering of the structure of DNA in the 1960s and concurrent advances in biochemistry and genetics. Molecular biology is one of three primary molecular-scale biological sciences, the others being biochemistry and genetics.
1 Students should know the parts and functions of the circulatory and respiratory systems and how they work together for respiration. 2  Students should also understand what homeostasis is and that all living things must be able to maintain homeostasis.
For Example: The respiratory system works with the nervous system because the brain tell â¦ s the respiratory system when to breathe in or breathe out. The respiratory system works with the skeletal system, by allowing the skeletal system to protect the respiratory organs, like how the ribs protect the lungs.
