| Question | Answer |
|---|---|
| newton's 2nd law | the acceleraton of an object depends mass and amount of force applied |
| speed | distances traveled divided by the time taken to travel that distance |
| velocity | quantity that tells both how fast and which direction |
| motion | change in motion relative to a reference point |
| acceleration | chance of velocity over time |
| momentum | a quantity defined as the product of mass and velocity on an object |
| newton's 1st law | an object at rest stays in rest and an object in motion stays in motion at a constant speed unless acted upon by a unbalanced force |
| newton's 3rd law | when one objects exerts a force on a second object the second object exerts and equal and oppisite force on the first |
| inertia | tendency of all objects to resist any change in motion |
| force | a push or pull exerted on an object in order to change the motion of an object |
| net force | is the combination of all the forces actin gon an object |
| friction | an unbalanced force |
| weight | a measure of gravitational pull on an object |
| mass | amount of matter in an object |
| gravity | a force of attraction between two objects that is due to their masses |
| newton | SI unit for force |

| Law of conversation of energy | a law that states energy cannot be created or destroyed only can be changed from one form to another |
| Dominance | occurs when certain alleles mask the expression of other alleles |
| Recessive | an allele that will be masked unless the organism is homozygous |
| Punnett Square | a type of graph used to predict genetic cross |
| Chromosome | the genetic information organized into structures |
| Meiosis | a process that produces cells with half the usual number of chromosomes |
| Asexual Reproduction | results in offspring with genotypes that are exact copies of there parents genotypes |
| Sexual Reproduction | results in offspring being genitally similar but not identical |
| DNA | genetic material stands for deoxyribonucleic acid |

| Ovary | the swelling at the base of the the flower (where eggs are) |
| Sepal | green leaf like part that protect the flower when it is in bud |
| Egg | in the ovule |
| Seed | the fertilizes matured ovule of a flowering plant, containing an embryo or rudimentary plant. |
| Gamete | a mature sexual reproductive cell, as a sperm or egg, that unites with another cell to form a new organism. |
| Zygote | the cell produced by the union of two gametes, before it undergoes cleavage. |
| Fertilization | the union of male and female gametic nuclei. |
| Pollination | the transfer of pollen from the anther to the stigma. |
| pH scale | scale used to measure how acidic something is |
