Chapter 1: humans in the world of biology. 1. living things contain nucleic acids, proteins, carbohydrates, and lipids. 2. living things are composed of cells. (1) unicellular organisms- organisms that only have a single cell. (2) multicellular organisms- organisms with trillions of cells. 4. living things use energy and raw materials. All chemical reactions that occur within the cells of living things. Maintains life and allows organisms to grow. 5. living things respond to their environment. The relatively constant and self-correcting internal environment of a living organism. 7. populations of living things have adaptive traits and evolve. Traits that help it survive and reproduce in its natural environment. (7. 2) this is also known as natural selection. Plants rooted on the surfaces of other plants. (2) all organisms came from the rst cells, but through evolution, diversity arose. (3) organisms with the greatest similarity are grouped together in domains. Eukaryotic cells that contain a membrane-bound nucleus and internal compartments (i. e. organelles)
