| A | B |
|---|
| Conduct an experiment | Used to affirm scientific ideas |
| Bias | Introduced in an experiment when told what to expect |
| Goggles | Critical to wear when working with chemicals |
| Foreign species | Responsible for the decline of native species |
| Dissolves | What happens to fluoride, salt, and other items when added to water |
| Monosaccharide | Building block of carbohydrates |
| Lipid | Most common type of molecule found in cell membranes |
| Protein | Built from amino acids |
| Nucleotide | Repeating units that form DNA molecules |
| Vitamin C | Wound healing |
| Vitamin D | Bone growth |
| Vitamin K | Blood clotting |
| Sugar and oxygen | During photosynthesis, these are made when plants convert carbon dioxide, water, and light energy |
| Osmosis | Process in which water moves across a selectively permeable membrane |
| Acidic | pH of less than 7 |
| Bacteria | Organism that converts nitrogen gas into ammonia |
| Light | Energy source used by plants |
| Oxygen | Gas released by plants during photosynthesis |
| Chemosynthesis | Energy in inorganic compounds is used to make sugars when no light is present |
| Cell membrane | Structure that allows some things to enter or leave the cell |
| Circulatory | System that transports glucose and other substances in the blood to the cells of the body |
| Excretory | System that removes metabolic wastes from the blood |
| Cilia | Short, hair-like structures on cells that are used for movement |
| Mitosis | Process of cell division; chromosome number stays the same; used for growth and repair |
| Chloroplast | Organelle used to make sugars |
| Meiosis | Process that produces gametes; chromosome number is divided by half |
| Zygote | Formed when an egg cell (n) and a sperm cell (n) combine to make 2n __________ |
| Genes | Segments of DNA that code for proteins |
| Gamete | Formed during meiosis, mutations must take place in these to be passed to offspring |
| Genetic variation | Necessary for natural selection to occur |
| Natural selection | Process that produces advantageous traits in modern organisms |
| Adaptation | Traits that help organisms to survive in the environment, such as large ears of rabbits in warm environments |
| Mutation | Causes variation in a species; change in DNA |
| Prokaryote | Classification of bacteria as they have no nuclei or membrane-bound organelles |
| Common ancestor | Similarities in proteins/skeletons/DNA suggest that organisms share this |
| Abiotic | Non-living things (temperature, sediments, etc.) |
| Biotic | Living things (algae, predators, etc.) |
| Parasite | Organism that feeds on blood of other organisms; lives in or on something to their detriment |
| Producer-->Herbivore-->Carnivore | How energy is usually transferred in a food chain |
| Succession | Different organisms inhabit an area at different times--series of community replacement |
| Biodiversity | This should be high to have a healthy ecosystem |
| Prey | Overpopulation of these will occur if the population of large predators decreases |
