Module 2: BIOD 101/ BIOD101 (Latest 2025/ 2026 Update) Essential Biology I W/Lab | Questions & Answers| Grade A| 100% Correct (Verified Solutions)- Portage Learning QUESTION What are ORGANISMS? Answer: Individual living things that make up a population. QUESTION What are ORGANISMS composed of? Answer: - Organ systems - Organs - Tissues - Cells - Atoms - Molecules QUESTION What is an ORGAN SYSTEM? Give an example. Answer: A group of organs working together to perform a particular function; an example of an organ system is the Urinary System, which consists of the kidneys, ureters, bladder, and urethra. QUESTION What are ORGANS? Give an example. Answer: Organs are groups of tissues that work together to perform certain functions; an example of an organ is the skin - the skin is the largest organ of the human body. QUESTION What are TISSUES? Answer: Tissues are groups of cells that are similar in structure and function. QUESTION What are CELLS? Answer: Cells are the basic units of structure and function in living things. QUESTION What are ATOMS AND MOLECULES? Give an example of each. Answer: Atoms = smallest unit of matter participating in chemical reactions; example: Oxygen Molecules = two or more atoms joined together; example: Dioxide QUESTION What is the LINNAEAN CLASSIFICATION SYSTEM? Answer: The system used to classify living things; the taxa of the Linnaean Classification System is ranked from broad to specific: Kingdom, Phylum, Class, Order, Family, Genus, and Species ("Dear King Philip Came Over For Good Soup"). QUESTION What are the three domains that comprise the Linnaean Classification System? Answer: Archaea, Eubacteria, Eukarya QUESTION What is PHYLOGENY? Answer: A strategy through which scientists trace the evolutionary history and diversification of a group of species. QUESTION What is the purpose of a PHYLOGENIC TREE? Answer: The purpose of a Phylogenic Tree is to show the relationship between different levels of Linnaean Classification taxa, each branch on a Phylogenic Tree represents where two organisms likely share a common ancestor. QUESTION What are ARCHAEA? Answer: Archaea are single-celled, microscopic organisms with a prokaryotic cell structure. QUESTION What are EXTREMOPHILES? Give examples. Answer: A small subset of archaea that thrive in extreme environments; - Thermophiles: extremophiles that thrive in high temperature environments, such as volcanoes - Halophiles: extremophiles that can be found in extremely saline environments, such as the Dead Sea - Psychrophiles: extremophiles that thrive in attic temperatures, such as the tundra of Antarctica QUESTION What are EUBACTERIA? Answer: Single-celled bacteria with a prokaryotic cellular structure that reproduce by binary fission. QUESTION What are the three different types of eubacteria? Answer: Pathogenic, non-pathogenic, and commensal
