scienceAnswers
Co-valent Bonding When two atoms are able to share electrons
Ionic Bonding Atoms lose or gain electrons to make each other complete (electrons are not shared)
Metal Atoms Tend to lose electrons
Non-Metal Atoms Tend to gain electrons
My Very Eager Mother Just Sold Us Nine Pizzas Mercury,Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto
Terrestrial Planets Four planets closest to the sun-Mercury, Venus, Earth and Mars
Terrestrial Planets Composition Rocky and small-dense in composition
Jovian Planets Jupitar, Saturn, Uranus, Neptune
Jovian Planets Composition Gaseous, large, outer planets and low in density
Archipelago A group or chain of island clustered together in a sea or ocean
Atoll A ring or partial ring, or coral that forms an island in an ocean or sea
Bay A body of water that is partly enclosed by land
Butte Flat-topped rock or hill formation with steep sides
Canyon Deep valley with very steep sides
Cape A pointed piece of land that sticks out into a sea, ocean, lake, or river
Cove A small, horseshoe-shaped body of water along the coast
Cave Is a large hole in the ground or in the side of a hill or mountain.
Cliff Is a steep face of rock and soil
Isthmus A narrow strip of land connecting two larger landmasses.
Strait A narrow bady of water that connects two larger bodies of water
Tributary A stream or river that flows into a larger river.
What accurs near plate boundaries? Geological activity, such as earthquakes, and volcanic eruptions, occus at or near plate boundaries.
Divergent Plate Boundaries Plates move apart
Convergent Plate Boundaries Plates move together
Transform Plate Boundaries Plates move past one another in opposite directions
Ignous Rock Formed from molten material, magma
Sedimentary Rock formed by settling to the bottom of oceans and lakes. (sandstone, shale, limestone)
Metamorphic Rock Ignous or sedimentary rock that has been changed by heat, pressure, or chemical action.(slate, gneiss,marble)
Isotope Atom is missing or has an extra neutron
Newtons Law #1 Things tend to deep on doing what they are doing unless acted upon. Example Yo-Yo
Newtons Law #2 The more mass you have the more acceleration you must have to get the same results.
Newtons Law #3 For every action there is an equal and opposite reaction. Example Rocket ship
Conduction Heat transferred by solids
Convection Heat transferred by liquids
Radiation Is the transfer of heat by electromagnetic waves.
Wave Length Refraction, reflection, diffraction, and interference
Oxidation Loss of an electron by a molecule, atom or ion
Reduction Gaining an electron by a molecule, atom or ion
Caytalyst Substance that accelerates the speed of a chemical reaction without itself being transformed or consumed by the reaction.
Ionic bond Between non metals and metals
Parallel Circuit When more then on path is provided for the passage of electrons divide themselves among the separate conductors and current flows in each of the paths.
Series Circuit When electrons follow a single path from their source to their destination.
Independent Varible Has the 'I' which means 'I' the experimenter is going to change. Example: using different types of meds to lower a fever. The meds are the independent varible and the fever the dependent varible.
Dependent Variable What you are trying to change. In the tomatoe plants the fertilizer is the independent varible and the growth of the plants is the dependent variable because that is what we were trying to change.
Acceleration The rate at which speed or direction is changing.
Displacement A vector or the magnitude of a vector from the initial position to a subsequent position assumed by a body. Refers to how far person or abject moved.
Velocity distance traveled in a specified amount of time (a change in velocity is called acceleration Newton's 2nd law) Is a measure of how fast a person or object got from one point to another and can be found by calculating the displacement over a certain time.
Speed the rate or measure of the rate of motion. Measures how fast a person or object has traveled over a certain distance in a certain amount of time.
Distance Refers to how far a person or object has traveled.
Velocity or average speed. The car covered 500 km in the first 10 hours of its nortthward journey (blank)
Velocity or Average speed: Five seconds into the launch, the rocket was shooting upward at 5000 meters per second. Velocity
Velocity or Speed: The cheetah can run at 70 mph. Speed
Velocity or Average Speed: Moving at five km per hour, it will take us eight hours to get to the base camp. Average Speed
Volicity or Speed: Roger Bannister was the first person to run one mile in less than four minutes. Average Speed
Non Polar Bonds With an equal sharing of electrons
Polar Bonds Unequal sharing of electrons

What planet rotates in the opposite direction of other planets Venus
Gonads Sex organs that produce Gametes
Sperm are produced by meiosis
Male Sex Hormones The anterior pituitary produces follicle-stimulating hormone (FSH) and luteinizing hormone (LH)
Luteinizing Hormone(LH) Stimulates cells in the seminiferous tubules to secrete testosterone.
Follicle-stimulating Hormone (FSH) Acts on cells to help in sperm maturation.
Estrogen Follicle secretes estrogen before ovulation
Corpus Luteum (blank)
corpus luteum Secretes both estrogen and progesterone.
List the organs and tissues the human body uses to fight off infection and disease Lymph nodes, spleen tonsils, thymus, and bone marrow.
