Term | Definition |
---|---|
extinction | Elimination of a species from Earth. |
evolution | Change of a species over time. |
synthesis | To make or build something. |
hormone | Chemical messengers that are sent through the bloodstream. |
reproductive success | The number of offspring an individual produces and rears to reproductive age. |
genetic variability | Each individual has a distinct set of genes among a species. |
mutation | A change in a gene or chromosome. |
inability | Not being able to do something. |
lethal | deadly; fatal |
migration | Movement from one place to another. |
marine life | Animals or plants that live in the oceans. |
natural oil seeps | Crude oil and natural gas naturally enter the ocean at areas known as "seeps." These hydrocarbons leak out of the ground through fractures in sediments. |
tubeworms | These organisms live over a mile deep, and up to several miles deep, on the floor of the Pacific Ocean near black smokers, and can tolerate extremely high hydrogen sulfide levels. |
giant mussels | The bivalve shell is usually 30 |
deep | sea crabs |
petrochemical | A chemical made from petroleum or natural gas. |
metabolism | All of the chemical reactions that occur within an organism. |
methane | A gas with no colour or smell that is used as a fuel. |
chemosynthesis | To make food using chemicals instead of sunlight. |
exploiting | Taking advantage of something for one's own advantage. |
adapt | A changing to fit new conditions. |
variation | Changes between organisms. |
natural selection | A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits. |
frequency | How often. |
gene frequency | How often a particular gene occurs in the population. |
survival value | How an animal's behavior allows it to better survive. |
atoms | Basic unit of matter. |
differentiation | The process by which cells develop a specialized form and function. (Cell Specialization) |
photosynthesis | Plants use the sun's energy to convert water and carbon dioxide into sugars. |
decomposers | Bacteria and Fungi that break down dead organic matter. |
Asexual Reproduction | Process of reproduction involving a single parent that results in offspring that are genetically identical to the parent. |
Mitosis | Form of asexual reproduction. Used by unicellular organisms for reproduction and multicellular organisms for tissue repair. |
Sexual Reproduction | A reproductive process that involves two parents that combine their genetic material to produce a new organism, which is a combination of genes from both parents. |
clone | A group of genetically identical cells or organisms derived from a single cell or individual by some kind of asexual reproduction. |
gamete | Sex cells. |
sex cells | sperm and egg cells |
chloroplasts | A plastid containing chlorophyll; the site of photosynthesis. |
Chlorophyll | A green pigment found in the chloroplasts of plants, algae, and some bacteria. |
