Principles of Biology BIOL 1504.9HO Week 1 Notes 1.1: Themes/ Concepts of Biology Biology the study of life The 8 Characteristics that define life are: Order (Atoms, to molecules, to cells, to cell components/organelles to organisms Example: Humans consist of cells that make up tissues and tissues that make up organs and organs that make organ systems) 1. Sensitivity/Response to Stimuli (Movement toward or away from a stimulus is responding to a stimulus. Moving away from a stimulus is negative while moving toward it is good. Example: Plants move toward sources of light if in need) 2. Reproduction (Duplicating their DNA to give genes to the offspring which may be eye color, hair texture, etc. Example: If two adults conceive a child and both have black hair and the child has black hair… they have reproduced and passed on their genes to their offspring.) 3. Adaptation (Being fit to an environment is due to evolution by natural selection. Adaptations are not constant and also increase reproductively. Example: Bears who live in cold climates have become accustom to the cold weather. They are able to master their environment where they can reproduce and flourish.) 4. Growth and Development (These aspects are dependent on instructions by the genes. Since genes are given by parents the offspring may have the characteristics of their parents.) 5. Regulation (Includes internally like digestion and handling stress in the environment) 6. Homeostasis (A steady state. Certain things are done inside of the organism to make sure everything is in line. Example: When organisms get to a high body temperature, sweating occurs. Whether that is through the tongue like dogs or through the skin like humans.) 7. Energy Processing (Using an energy source for metabolism. Example: Humans consume food for energy while plants use sunlight to make food in a process call photosynthesis. ORDER OF LIFE 1. Atom smallest unit of matter 2. Molecule two atoms together in a chemical substance 3. Organelles cells surrounded by membranes 4. Cell smallest function in living organisms 5. Tissues groups of cells that have the same function 6. Organs collection of tissues with the same function 7. Organ System group of organs with the same function 8. Organisms individual living things 9. Population individuals within a species in a specific area together 10. Community populations living in the same area 11. Ecosystem all living things in a specific area (nonliving included ex: rain, soil, etc.) 12. Biosphere collection of ecosystems Macromolecules biologically important molecules Example: DNA Monomers small units= large molecules All living things are mad of cells Viruses are not living because they are not made of cells. They have to attack a living cell to then multiply Prokaryotes single celled organisms that don’t have a nucleus Eukaryotes Evolution a change in which a new species stems from an older one In the 18 century Carl Linnaeus first organized living things into a hierarchical system (Currently the system has 8 levels, from low to high which are: species, genus, family, order, class, phylum, kingdom, domain. Phylogenetic Tree of Life page 14 Figure 1.11 (Look at the graph and description above) 1.2: Process of Science Science knowledge about the world Scientific Method a method of how to carry out a procedure which consists of observation, measurement, experiment, formulas, testing, and resulting in a hypothesis Hypothesis an explanation that can be tested (a starting point to future research) Scientific Theory an explanation of the natural world based on facts Scientific Laws mathematical formulas Natural Sciences sciences related to the natural world Life Sciencesstudies living things (Example: biology) Physical Sciences studies nonliving matter (Example: astronomystars, sun, space, etc.) Inductive Reasoning logical thinking using observations to reach a conclusion Deductive Reasoning logical thinking using laws/ principles to get a specific result Descriptive/ Discovery Science hands on (observe, explore, and discover) Hypothesis Based Science begins with a question and answer to be tested Falsifiable can be proven wrong Variable any part of the experiment that can change Control does not change in the experiment Basic/Pure Science focuses on increasing knowledge Is not focused on developing a product Applied Science (technology) The goal is to solve realworld problems. Contrast to Basic/ Pure Science.
