| Question | Answer |
|---|---|
| Adaptation | A process by which a population becomes better suited to its environment by increasing the frequencies of alleles that provide benefits to survival and reproduction |
| Air Mass | A body of air extending over a large area (1,000 miles or more) that develops and retains specific characteristics of pressure, temperature, and humidity |
| Allele | A version of a gene |
| Anther | The part of a flower that contains the pollen; located at the end of the stamen |
| Asexual Reproduction | The reproductive process that involves one parent and produces offspring identical to the parent |
| Atmosphere | The layer of gas surrounding a planet that is held in place by gravity |
| Behavior | What a plant or animal does |
| Brain | The organ that serves as the primary control center of the nervous system in all vertebrate and most invertebrate animals |
| Chemical Input | A chemical that enters the body |
| Chromosome | A single, highly organized and structured piece of DNA |
| Cold Front | The border between an advancing mass of cold air mass and a retreating warm air mass |
| Electromagnetic Input | Signals that enter the body in the form of electromagnetic stimuli |
| Environmental Factor | Any factor, whether abiotic or biotic, that influences living organisms |
| Forecast | A prediction or estimate of future events |
| Gene | The basic physical and functional unit of heredity made up of DNA |
| Genetic Factors | Things that result from the specific alleles carried by an individual |
| Genetic Variation | The variety of gene combinations that exist within a population |
| Global Winds | Winds that act as a heat transfer system due to the unequal heating of Earth’s surface |
| Growth | Process of increasing in size and maturity |
| Inherited Trait | A characteristic that is passed from parent to offspring |
| Landforms | Features on the surface of Earth, such as mountains, hills, dunes, oceans, or rivers |
| Mechanical Input | Signals that enter the body through physical touch or vibration |
| Nerve Cell | A cell specialized for transmitting fast electrochemical signals |
| Ocean Currents | Directional movements of ocean water; surface currents result from steady winds over the ocean surface; deep currents result from density variations due to temperature and salinity differences |
| Offspring | Product of reproduction; a new organism produced by one or more parents |
| Organism | A self-contained living thing |
| Ovary | A female reproductive organ that produces eggs |
| Petals | The colorful, leaflike structures that encircle the center part of the flower |
| Pistil | The female structure of the flower; contains the stigma, style, and ovary |
| Pollen | Fine to coarse particles spread from flowers and seeds of plants |
| Pollination | The process of fertilizing flowers by transferring pollen from the male to female parts |
| Probabilistically | Based on probability |
| Punnett Square | A tool used to analyze the possible allele combinations of the offspring between two individuals |
| Reproduction | The process by which organisms produce more of their own kind |
| Sensory Receptor | A nerve ending that sends signals to the central nervous system when it is stimulated |
| Sexual Reproduction | The reproductive process involving two parents whose genetic material is combined to produce a new organism different from themselves |
| Specialized | Having characteristics that allow specific functions to be performed |
| Stamen | The male structure of the flower; contains the anther and filament |
| Stimulus | An action or condition that provokes a response |
| Variation | The occurrence of an organism, trait, or gene in more than one form |
| Warm Front | The boundary between an advancing warm air mass and a receding cooler air mass |
| Weather | The day-to-day state of the atmosphere |
| Weather Map | A map or chart that shows the weather conditions at a specific point in time over a specific region |
| Weather Pattern | Similar weather for a certain number of days |
