Answer:
1. connected by direct genetic relationship rather than by adoption or marriage
2. of or relating to biology or life and living processes
3. used in or produced by applied biology
Step-by-step explanation:
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life.
