Gradualism | A theory that a species evolves over a slow and continuous time. |
Punctuated Equilibria | A theory that new species evolve suddenly over relatively short periods of time and then evolve more slowly over longer periods of time. |
Natural Selection | Traits that organisms have that enable them to adapt to specific environmental pressures. |
Over Production | Production in excess of need. |
Petrification Of Fossils | Converting fossils into a stone. |
Competition | The struggle between different organisms to meet their needs. |
Osmosis | The diffusion between fluids. |
Diffusion | The act of a substance moving from a higher concentrated area to a lower concentrated area. |
Active And Passive Transport | Active transport is when energy is needed to allow a substance through the membrane of a cell. Passive transport is when no energy is needed to allow a substance through the membrane of a cell. |
Enzyme | Proteins that are a biochemical catalyst produced by living cells. |
Catalyst | A chemical that speeds up a chemical reaction. |
Autotroph | Makes its own food-Producer |
Heterotroph | Doesn't make its own food-Consumer |
Decomposer | An organism that breaks down the cells of dead plants and animals into simpler substances. |
Genotype | The total number of genes transmitted from a parent to an offspring. |
Phenotype | The appearance of an organism depending on the genotype. |
Heterozygous | Having unsimiliar genes for any hereditary characteristic. |
Homozygous | Having identical pairs of genes for any hereditary characteristic. |
Allele | Any form of a gene usually through mutation. |
Probability | The chance that something will happen. |
Genetic Code | The sequence of nucleotides in DNA or RNA that determine the specific amino acid sequence in the synthesis of proteins. |
Chloroplast | Organelles that produce the cells food(glucose) using the sun. |
Chlorophyll | The green coloring of leaves that is needed to produce carbohydrates during photosynthesis. |
Phloem | Carries synthesized nutrients to all parts of a plant in vascular plants. |
Xylem | Carries water and dissolved minerals from the roots to the plant in vascular plants. |
Gymnosperm | A vascular plant that has seeds that aren't enclosed in the ovary. |
Angiosperm | A plant that has its seeds enclosed in the ovary. |
Germination | To start growing from a seed. |
Cerebrum | The largest part of the brain that controls voluntary movements and mental actions. |
Cerebellum | It coordinates voluntary movements, posture, and balance. It is located under the cerebrum. |
Stimuli | Something that encourages an activity or process to begin, increase, or develop. |
Vaccine | A preparation to that causes immunity to a specific disease. |
Compound | Composed of two or more elements. |
Homogeneous Mixture | A substance that has a uniform composition and properties. |
Heterogeneous Mixture | A substance that doesn't have a uniform compostion and properties. |
Viscosity | The property of a fluid that resists the force tending to cause the fluid to flow. |
Boyle's Law | The inverse variation of the volume of gas with its pressure if the temperature and the number of particles are constant. |
Charles Law | The direct proportion of the volume of gas to its temperature(kelvins)if the pressure and the number of particles of the gas are constant. |
States Of Matter | Solid,liquid,gas,plasma,Boce-Einstein Condensate. |
Condensation | The phase change in which a substance changes from a gas or vapor to a liquid. |
Melting | The phase change in which a substance changes from a solid to a liquid. |
Vaporization | The phase change in which a substance changes from a liquid to a gas. |
Deposition | The phase change in which a substance changes from a gas or vapor to a solid without first changing to a liquid. |
Sublimation | The phase change in which a substance changes from a solid to a gas or vapor without first changing into a liquid. |
Momentum | The product of an object's mass and velocity. |
Inertia | The tendency of an object to resist a change in its motion. |
Equilibrium | A state in which the forward and reverse paths of a physical or chemical change take place at the same rate. |
Newton's Laws | 1. An object will stay in motion or at rest unless it is acted upon by an unbalanced force.2. Force equals mass times acceleration. |
Ionization | The process by which neutral molecules gain or lose electrons. |
Flagella | A long, lashlike appendage serving as an organ of locomotion in protozoa, sperm cells, etc. |
Antibiotic Resistance | The ability of a microorganism to produce a protein that disables or prevents transport of the antibiotic into the cell. |
