Properties Unand of Life ' Living - things can Metabolize - 1. produce - Sexual VS Asexual Genome Inherited genetic material - - 2. Evolve (Change) organisms adapt to their environment - -changes are inheritable. 3 Grow and Develop Growth-Increase In the number/size of cells Development - changes which occur through the life-span - Genetic information controls differentiation 4. Obtain + use energy Metabolism sum of allchemical reactions - - Catabolism us - Anabolism Take small - * things to build Taking big structures bigger things and break them down. 5 Respond (or react to their environment 6 Regulate. - biological processes Maintain homeostasis & Body Itself balances regardless of environment.
