Biology Chapter 1 Qs
Study Guide Q's for Chapter 1
| Question | Answer |
|---|---|
| Metabolism | The sum total of all processes in an organism which converts energy and matter from outside sources and use that energy to sustain the organisms life functions |
| Anabolism | The sum total of all processes in an organism which use energy and simple chemical building blocks to produce large chemicals and sructure necessary for life |
| Catabolism | The sum total of all processes in an organism which break down chemicals to produce energy and simple chemical building blocks |
| Photosythesis | The process by which green plants and some other organisms use the engery of sunlight and simple chemicals to produce food |
| Herbivores | Organisms that only eat plants |
| Carnivores | Organisms that only eat organisms other then plants |
| Omnivores | Organisms that eat both plants and other organisms |
| Producers | Organisms that produce their own food |
| Consumers | Organisms that eat living producers and/or other consumers for food |
| Decomposers | Organisms that break down dead remains of other organisms |
| Autotrophs | Organisms that are able to make their own food |
| Heterotrohps | Organisms that depend on other organisms for their food |
| Receptors | Special structures that allow living things to sense the condition of their internal or extrenal enviornment |
| Asexual Reproduction | Reprodutcion accomplished by a single organism |
| Sexual Reproduction | Reprouction that requires two organisms |
| Inheritance | The process by which physical and biological characteristics are transmitted from the parent(s) to the offspring |
| Mutation | An abrubt and marked change in DNA |
| Hypothesis | An educated guess that attemps to explain and observation or answer a question |
| Theory | A hypothesis that had been tested with a significant ammount of data |
| Scientific Law | A theory that had been tested by and is consistant with generations of data |
| Micro-organisms | Living creatues that are too small to see with the naked eye |
| Abiogenesis | The idea that long ago very simple life forms spontaneously appeared through chemical reactions |
| Prokaryotic Cell | A cell that has no distinct membrane-bounded organelles |
| Eukrayotic Cell | A cell with distict membrane-bounded organelles |
| Species | A unit of one or more populations of indivduals tht can reproduce under normal condiions, produce fertile offspring and are reproductivly isolated from |
| Taxonomy | The science of classifying organisms |
| Binomial Nomenclature | Naming an organism with its genus and speices name |
| What are the four criteris for life? | 1) Can reporduce 2) All life forms have a method by which they extract energy from the surroundings and convert it into energy that sustains them 3) All life forms can sense changes in their surroudings and respond ot those changes 4) Contains DNA |
| An organ is classified as a carnivoreIs it a heterotroph or and autotroph? | Heterotroph |
| Is an organ and producer, consumer, or decomposer? | Consumer |
| An organism has receptors on tentacles that come out of its head. If those tentacles were cut off in and accidenet, what life function would be most hampered? | Touch "Sense" |
| A parent and two offspring are studied. Althoguh there are many similarites between the parent and the offspring, there are also some differances. Do these organisms reproduce sexually or asexually? | Sexually |
| What is wrong with the following statement? "Science has proven that energy must always be conserved?" | Science can't prove anything |
| Briefly explain the Scientific Method | It starts with Observation, then they form an hypothesis form the info gathered. Then the hpothesis is tested. After continuous testing/results it becomes a theory. After several generations of consistent data is becomes a scientific law |
| Why does the story of spontaneous generation illustrate the limitation of science? | B.c thye believed in something that was wrong for 200 years. So you cant put to much faith in science. |
| Where does the wise person place their faith: Science or the Bible? | The Bible |
| Why is the theory of abiogenesis just another exapmle of the idea of spontaneous generation? | Because it is the idea that long ago, very simple life formes spontaneously appeared through chemical reaction |
| Name the classidication groups in out heirarchial classification scheme in order. | 1)Kingdom 2)Phylum 3)Class 4)Order 5)Family 6)Genus 7)Species |
| An organism is a muticellular consuker made of eukaryoitc cells. To what kingdom does it belong? | Animalia |
| If you were using the three domain system of classification, in which domain would the organism in Q #12 belong? | Eukarya |
| An orgainsim is a single-celled comsumer made of prokaryotic cells. To what kingdom does it belong? | Monera |
| If you were using the three-domain system of classification, could you deterone the domain of the organism in #14? If so, give the domain. If not, give the possible domains in which it could be placed. | It could go into either Archaea or Bacteria depending on where it is. |
