| What is respiration and what does it require? | Respiration is a mammals way of making energy. It needs water and oxygen |
| What does respiration produce? | Respiration produces energy, water vapor, and carbon dioxide |
| What happens when a cell differentiates? | When a cell differentiates it becomes part of a tissue or organ |
| What are the important parts of a leaf? | THe important part of leaves are chloroplast(collect sunlight), stomata(small holes that allow gaseas in and out ), chorophill(green pigment in the lleaf/plant caused by chloroplast) and acuticle (top of leaf that stops water from evaporating) |
| What is heredity? | The passing of characteristics from parent to offspring |
| What determines the height of an organism? | A trait that comes from the organisms' parents |
| What is fermentation? | Fermentation is making energy without the use of oxygen |
| What are the stages of the cell cycle? | The stages are interphase(1), mitosis(2), and cytokinesis(3) |

| What is the difference between dominant and ressesive alleles? | The dominant allele is the allele that always shows when present. The recessive is the allele hat doesnt show when the dominant allele is present |
| genotype | an organism's allele combinations |
| phenotype | an organism physical traits |

| carrier | -a person who has one recessive allele and one dominant allele |
| what phase the in cell cycle does replication occur? | Interphase |
| pedigree | - a chart that can track which family member haves a particular trait |
| punnet square | -a chart that shows all possible combinations of alleles from genetics |
| genetic disorder | -an abnormal condition that a person inherits through genes |
| sex chromosomes | - one of the 23 pair of chromosomes |
| multiple alleles | -three or more genes that control a single triat |
