Adaptation is the term for a population that changes over time. In the case of humans, we inherit one set of traits from each parent, creating genetically unique offspring.Īll living organisms evolve and adapt to their environments through a process called natural selection. Many of these traits are inherited, which means that information was passed down from a parent to an offspring. Proteins are also important because they help produce different physical or biochemical traits, such as body shape, growth rate, and hair color. Enzymes also assist organisms in reproduction and in responding to their surrounding environment. For example, enzymes transform raw chemical materials and convert them into energy and wastes. Enzymes are essential to life because they help chemical reactions occur quickly and at relatively low temperatures. Enzymes are proteins that allow organisms to accelerate life processes. Genes can produce proteins, some of which are specialized proteins called enzymes. In most organisms, RNA (ribonucleic acid) comes from DNA and is the part of the genetic blueprint that codes for individual genes and proteins.Ī gene is a portion of DNA that contains the information for a certain trait or molecule. DNA (deoxyribonucleic acid) is a molecule that is stored in a cell and contains the genetic blueprint to make an entire new organism. All living organisms store hereditary information in the form of nucleic acid molecules, such as DNA or RNA. Trait information can include physical and biochemical characteristics such as eye color in humans or fur patterning in cats. Heredity is the passing of information about traits from one generation to the next. If properties 4–5 are also included in the definition of life, a virus would not be considered alive. If properties 1–3 are used to define life, a virus is considered alive. ![]() adapt to the environment and have an evolutionary history.use enzymes to speed and mediate reactions.The following are characteristics that most scientists agree all living things share.
