Document Summary
Chapter 1a: humans in the world of biology: The amazon rainforest has lots of life present-it has so much biodiversity and scientists are in search of its secrets, including plants that may have healing qualities. No single definition of life satisfies all life scientists -we can"t define life, we can only characterize it. Living things contain nucleic acids, proteins, carbohydrates, and lipids. Living things can combine certain of 100 combinations of elements to create molecules that are found in all living organisms, including nucleic acids, proteins, carbohydrates, and lipids. Dna is especially important because dna molecules can make copies of themselves, an ability that enables organisms to reproduce. The ability of cells to divide to form new cells makes reproduction, growth, and repair possible. Living things grow and generate individuals that carry some of the genetic material of the parents. Metabolism refers to all chemical reactions that occur within the cells of living things.
