Living or Nonliving
| Question | Answer |
|---|---|
| asexual reproduction | reproduction that does not involve sex cells and in which one parent produces an identical offspring. |
| competition | the struggle for limited resources |
| consumer | an organism that eats other organisms |
| decomposer | an organism that gets energy by breaking doewn dead organisms or animal waste and absorbs nutrients |
| heredity | the passing of genetic traits from parent to offspring |
| homeostatsis | the maintenance of a constant internal sate in a changing enviornment |
| metabolism | the sum of all chemical processes that occur in an organism |
| multicellular | organism with more than one cell |
| producer | an organism that can produce (make) its own food |
| response | reaction to a stimulus or change in enviornment |
| sexual reproduction | reproduction in whcih sex cells from two parents unite and produce an offspring with shared characteristics from both parents |
| stimulus | anything that causes a reaction or change in an organism or any part of an organism |
| unicellular | an organism made up of one cell |
| 6 characteristics of living things | 1.) Cell(s) 2.) Sense & Respond to Change 3.) Reproduction 4.) DNA 5.) Grow & Develop 6.) Use Energy |
| Examples of unicellular organisms | bacteria, ameba, paramecium, yeast |
| Examples of multicellular organisms | human, dog, fish, bird, flower |
| Examples of stimuli | loud noise, bright light, temperature change |
| Examples of responses | jump, run, cover eyes, change direction of growth, shiver |
| Examples of organisms that reproduce asexually | bacteria, protist, yeast |
| Examples of organisms that reproduce sexually | humans, birds |
| How do you maintain a constant body temperature (homeostasis)? | when you are hot you sweat, when you are cold you shiver |
| 4 complex activities of metabolism | Ingestion (intake), Digestion (break down), Excretion (get rid of waste), Respiration (use oxygen to produce energy) |
| 4 Basic Needs of Living Things | Water, Air, Food, Living Space |
| Why do plants need carbon dioxide? | to make their own food in the process of photosynthesis |
| Why is water so important to living things? | helps transport materials and needed for many chemical reactions to take place |
| What precentage of your cells are made up of water? | 70% |
| 5 Compounds Found in cells | Proteins, Carbohydrates, Lipids, ATP, Nucleic Acids |
| Building Blocks of Protein | Amino Acids |
| Phospholipids | molecules that form much of the cell membrane |
| Which organic compounds are broken down and provide the cell with energy? | carbohydrates & lipids |
| How are DNA and RNA similar | Both nucleic acids |
| How are DNA and RNA different? | DNA: stores/caries genetic information RNA: "Reads" information |
