| A | B |
| DNA shaped like | a Spiral Staircase |
| Fermentation | Production of energy without using oxygen |
| Respiration | Glucose is broken down releasing energy |
| Oxygen | Product of photosynthesis that most living things need to survive |
| Products of photosynthesis | Oxygen and Sugars |
| Vacuoles | Organelles that store food/materials needed by cell |
| Carbon | Organic compounds contain this element |
| Mitochondria | Organelle that produces energy for the cell |
| XY | Sex chromosomes resulting in male human |
| Tt | One dominant and one recessive allelle |
| Genes | Factors that control traits |
| Chlorophyll | Captues energy from sunlight during photosynthesis |
| Cancer begins with... | Mutation in DNA |
| Insects perfectly preserved in | Amber from hardened tree sap |
| Evolution | The gradual change in a species over time |
| Extinct | Species that no longer have any living members |
| Fossils | The preserved remains or traces of organisms thatlived in the past |
| Genetic disorders caused by.. | mutations |
| You feel thirsty when... | Your brain sends a signal that your body needs water, maintain homeostasis |
| Tissue | A group of cells that perform a similar function |
| Small Intestion | Where most of the nutrients are ABSORBED |
| Calorie | Unit used to measure ENERGY |
| Cardiac Muscle | Found only in the heart |
| Function of skeleton | Shape & support,protects organs,produce blood cells |
| Nucleus | Directs activities of the cell |
| Plant cell parts ONLY | Cell wall, chloroplast, LARGE vacuole |
| Sunlight or solar energy | Form of energy taken in by plant for photosynthesis |
| Cell Theory | cells produced from cells,living things made of cells,basic unit of structure and function |
| SPECIALIZED cells found in.. | Many-celled organisms |
| Diffusion | Movement of molecules from higher to lower concentration |
| Mitosis | Stage during which cell's nucleus divides into 2 nuclei |
| PEDIGREES used to.. | trace inheritance of traits |
| Hybrid | Organism with 2 different alleles for a trait |
| Replication | Cells DNA is copied |
| Most fossils form by.. | Dead organism buried in sediment |
| One main way new species form | A group is separated from rest of the species(island) |
| Species is group of similar organisms... | that can mate and produce offspring |
| Each sex cell contributes... | 1/2 the number of chromosomes |
| Genes are located... | On the chromosomes |
| Selective Breeding | Crossing different parents to get desired traits in offspring |
| Sexual Reproduction... | Greater variety in offspring |
| Skeletal muscles work in pairs because... | Muscles can only contract |
| VILLI in small intestine | Finger-like projections for absorption of nutrients |
| Large Intestine | Where water is absorbed & undigested material prepared for removal |
