Biology
| Question | Answer |
|---|---|
| Why Biology | Knowing yourself, your world, and your God |
| What is science | It is a process that aims to understand and explain hoe the natural world operates. It is a way of knowing. |
| Science is | An activity or a process |
| Hypothesis | A proposed explanation or prediction, generally lacks evidence/support, but is testable and potentially falsifiable. |
| Law | It describes what creation/nature does under certain conditions, generalizations related to the way some aspects of the world behave in certain conditions, usually mathematical. |
| Theory | They are inferred explanations of some aspect of the natural world. Theories are not law, but they attempt to explain laws. |
| Aspect 1 | Science is characterized by its demand for empirical evidence for its conclusion. |
| Aspect 2 | Science is characterized by its demand for logical reasoning. |
| Aspect 3 | Science gibes tentative or contingent knowledge. |
| Aspect 4 | Science has an epistemological framework which includes a set of presuppositions. |
| Aspect 5 | Science as a human activity has limits. |
| Aspect 6 | Science takes place within the values and norms of the culture and is subject to the biases of its practitioners. |
| A inductive argument is | Specific to general. |
| A deductive argument is | General to specific. |
| Control | Extraneous variables or confounding variables. |
| p Value | The probability of obtaining your results by chance alone. |
| p< 0.05 | Accepted hypothesis. 5 percent or less. |
| p> 0.05 | Rejected hypothesis. 5 percent or more. |
| Correltation | The measure of the degree of the relationship between two variables. |
| Perfect Positive Correlation | As one variable increases, the other increases at the same rate. |
| High Positive Correlation | Both variables increase but at different rates. |
| Low Positive Correlation | Both variables increase but one increases at a much faster rate then the other. |
| Negative Correlation | As one variable decreases, the other decreases at the same rate. |
| Presupposistions | Non-testable assumptions which are the foundation to a set of beliefs, worldviews, etc. |
| Scientists' models of the natural world are shaped by their | Philosophical commitments, religious beliefs, political views, and professional interests. |
| Reproducibility | Obtaining consistent results/conclusions analyzing the same data, using the same methods of analysis. |
| Replicable | Reaching the same conclusions, coming up with the same answers using new data, or different data. |
| Biology | It is the composition of living matter and function. The study of life. |
| The Organization of Life | It is a hierarchy of levels of increasing complexity. |
| 5 general themes that the study of life is organized around. | Evolution, the flow of energy, cooperation, structure determines function, and homeostasis. |
| Organisms 1 | The same kinds of atoms/molecules, according to the same laws of energy, biomolecules. |
| Metabolism | All chemical and physical processes involved in the transforming of energy and matter so that life can be maintained. |
| Organisms 2 | Consist of cells. |
| Organisms 3 | Use energy and raw materials from the environment to survive and reproduce. |
| Organisms 4 | Sense and make controlled responses to the conditions in their external and internal environment to regulate homeostasis. |
| Organisms 5 | All organisms have the capacity to reproduce and pass genetic information to future generations from parents to offspring. |
| Organisms 6 | Living organisms adapt to the environment. |
| Theory 1 | The cell theory. |
| Theory 2 | The gene theory. |
| Theory 3 | The theory of heredity. |
| Theory 4 | the theory of Evolution. |
| Evolution | Concept of unity and diversity of living organisms. |
| Atom | The smallest component of an element that retains all the different properties of that element. |
| Octet Rule | Most stable with 8 electrons in outer shell(ring). |
| Ionic bond | One atom donates an electron to another. |
| Covalent bond | Sharing of a pair of electrons between two atoms. May be polar. |
| Hydrogen Bonds | Bond of hydrogen from one molecule to a oxygen or nitrogen of another molecule. Very weak bonds. |
| 1 key element of water | Water functions as a biological solvent. |
| 2 key element of water | Water molecules have adhesion and cohesion. |
| 3 key element of water | Water absorbs and holds heat. |
| Cohesion | When one water molecule is attracted to another molecule. Has to do with surface tension. |
| Adhesion | When polar molecules other than water stick to a water molecule. |
| pH scale | The measure of the relative amounts of hydrogen and hydroxide ions in a solution. |
| Basic | pH greater than 7. |
| Acid | pH less than 7. |
| Neutral | Water, pH at 7. |
| Buffers | They regulate the pH of body fluids and maintain homeostasis. |
| Macromolecules | The building materials of the cell/body of living organisms. Usually assembled from monomers. |
| Types of macromolecules | Carbohydrates, lipids, proteins, and amino acids. |
| Biomolecule monomers | Monosaccharides, fatty acids, amino acids, and nucleotides. |
| Lipids | Form hydrocarbon chains. |
| Steroids of sterols | Backbone of 4 carbon rings, Cholesterol. |
| Sickle Cell Anemia | Change in the primary structure of hemoglobin. |
| Prions | Disease causing proteins, misfolded proteins, corrupt other proteins. |
| DNA | Double helix, backbone made of sugar and phosphorates, "rungs' made of nitrogenous bases. |
| Nucleic Acid | Composed of phosphate, sugar, and base. Function is genetic code, energy currency(ATP), and metabolic roles(NAD, FAD) |
