Document Summary

An organism which secretes enzymes externally into its environment to digest organic materials which are then absorbed, e. g. fungi, many protists and monera. Algae: unicellular or multicellular protoctists that have chlorophyll and other pigments. e. g. the seaweeds,diatoms, and spirogyra. Anaerobic: relating to, involving, or requiring an absence of free oxygen. Animals are multicellular, eukaryotic organisms, which are heterotrophic, meaning they obtain nutrition from organic sources. Most animals obtain nutrition by ingesting other organisms or decomposing organic material. e. g. human, cat. Antibodies combine chemically with substances that the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood. A toxin or other foreign substance that induces an immune response in the body, especially the production of antibodies. Antibiotic resistance evolves naturally via natural selection through random mutation, but it could also be engineered by applying an evolutionary stress on a population.
