This document discusses the relationship between biology and other sciences. It begins by defining biology and science, and noting that they are connected. It then provides examples of interdisciplinary sciences that combine biology with other fields like physics, chemistry, mathematics, geography, and economics. These include biophysics, biochemistry, biomathematics/biometry, biogeography, and bioeconomics. It concludes by assigning students to draw a figure showing the relationship between biology and other sciences for homework.
