Why study cellular and molecular biology? - Answer The connecting basis of all life is at the cellular and molecular level. DNA, RNA, proteins and the cellular mechanisms behind each of these form the fundamental basis of life. Many biological phenomena are better understood at the biochemical and molecular level. What are the 8 emergent properties of life? - Answer Reproduction Growth and Development Order and Structure Metabolism Respiration Response to environmental stimuli Ada...
