PROFICIENCY REVIEW #2
WHICH OF THE FOLLOWING IS NOT A RENEWABLE ENERGY SOURCE?
Nuclear
BASED ON IT’S POSITION ON THE PERIODIC TABLE, URANIUM IS A METAL.
KNOW THE DIFFERENCE…
Convection—movement of heat through a fluid.
Conduction—movement of energy, like electricity.
Refraction—to bend light. (example is why a spoon looks bent in a glass of water)
Radiation—energy from the sun.
WHAT HAPPENS TO ELECTROSTATIC FORCE AS AN OBJECT GETS CLOSER?
It increases…think of a magnet—the closer together you bring it, the stronger the force of attraction.
ENVIRONMENTAL CHANGES HAVE CAUSED MOST EXTINCTIONS.
NUCLEAR ENERGY:
Fission—to break apart (Helium into 2 Hydrogen atoms)
Fusion—to join together (2 Hydrogen come together to make a Helium molecule)
In both cases, matter is changed to energy.
IMAGES FROM A SPACE TELESCOPE (HUBBLE) ARE NOT DISTORTED, THAT IS WHY THEY ARE BEST TO USE.
THE FORCE ACTING ON AN OBJECT BEING DRAGGED ACROSS THE FLOOR = FRICTION.
BOUNDARY ON THE OCEAN FLOOR BETWEEN PLATES IS A MID-OCEAN TRENCH!
MITOCHONDRIA
Cellular Respiration ATP Energy Found more in muscle cells
THE BOND ANGLE OF WATER IS BENT.
WHILE WATER TRAVELS THROUGH THE WATER CYCLE, WHY DOES THE WATER EVAPORATE AND THE SALT DOES NOT?
Salt compounds do not evaporated from the water solution because they have a higher evaporation point than the water. So, the water evaporates, leaving the salt behind.
KMT
Kinetic Molecular Theory Which has the highest kinetic energy? Ice
water, Ice cream, Hot coffee, or Boiling water?
• BOILING WATER!• The hotter something is, the greater the kinetic
energy.
SOLID
LIQUID GAS
CURRENTS IN A BATTERY WIRE PRODUCE AN ELECTROMAGNETIC FIELD. SO, WHEN YOU HOLD A COMPASS NEAR A BATTERY WIRE, IT WILL CHANGE DIRECTIONS.
PHOSPHORUS
Number of protons… 15 Number of neutrons… 16 Number of electrons… 15

ONE ADVANTAGE TO SEXUAL REPRODUCTION IS GREATER VARIATION AMONG ORGANISMS.
WHAT IS THE MAIN CAUSE OF GLOBAL WIND PATTERNS?
Rotation of the Earth Coriolis effect
THE GREEN HOUSE EFFECT LEADS TO…
An increase in temperature An increase in the levels of carbon dioxide Acid rain *The greatest contributor to the green house
effect increasing the levels of CO2 in the atmosphere is the burning of fossil fuels.
PNEUMONIA LEADS TO AN INCREASE IN FLUIDS IN THE LUNGS, WHICH DECREASES THE OXYGEN TO THE CELLS.
MOH’S HARDNESS SCALE, AND THE PERIODIC TABLE ARE BOTH SIMILAR BECAUSE THEY ARRANGE THINGS ACCORDING TO SIMILAR PROPERTIES.
HardnessMineral
Associations and Uses
1Talc Talcum powder.
2Gypsum Plaster of paris. Gypsum is formed when seawater evaporates from the Earth’s surface.
3Calcite Limestone and most shells contain calcite.
4Fluorite Fluorine in fluorite prevents tooth decay.
5Apatite When you are hungry you have a big "appetite".
6Orthoclase Orthoclase is a feldspar, and in German, "feld" means "field".
7Quartz
8Topaz The November birthstone. Emerald and aquamarine are varieties of beryl with a hardness of 8.
9Corundum Sapphire and ruby are varieties of corundum. Twice as hard as topaz.
10Diamond Used in jewelry and cutting tools. Four times as hard as corundum.
ELEMENTS THAT ARE IN NUCLEAR FUSION LIKE THE STARS AND SUN ARE…
Hydrogen and Helium
COMPARING GENETIC SEQUENCES WILL BEST TELL HOW CLOSELY TWO SPECIES ARE RELATED.
HUBBLE’S LAW:
The universe is expanding at a constant rate. It appears to be moving away from us.
WHY WOULD A GENETIC MUTATION NOT BE PASSED ON?
Because it is SOMATIC, or occurs within the body cells, and is not inherited.
THE ROLE OF A DECOMPOSER IN AN ECOSYSTEM IS TO BREAK DOWN DEAD ORGANIC MATTER.
WHY DOES A HOT AIR BALLOON RISE WHEN HEATED?
Hot air rises, cold air sinks when compared to ambient temperature in the air.
HOW IS METAMORPHIC ROCK FORMED?
Heat and pressure.
WHICH SUBSTANCE CAN BE SEPARATED EASILY? HETEROGENEOUS OR HOMOGENEOUS
Heterogeneous—you can pick out the individual parts because they are different.
WHAT DOES IT MEAN TO BE UNETHICAL IN SCIENCE?
Fudging data Making stuff up Not doing multiple trials
MOST OF THE WORLD’S ENERGY COMES FROM THE SUN—SOLAR ENERGY.
THE HIMILAYAN MOUNTAINS ARE GAINING HEIGHT BECAUSE TWO PLATES ARE CONVERGING OR RUNNING INTO EACH OTHER AND UPLIFTING—CAUSING THE LAND TO RISE.
INCREASING THE NUMBER OF RESEARCH GROUPS IS AN ETHICAL WAY OF GETTING A MEDICINE APPROVED FASTER.
TECTONIC PLATE MOTION CREATES WHAT ENERGY SOURCE?
Geothermal
WHEN A BODY CELL DIVIDES, IT PRODUCES TWO COPIES WITH THE SAME DATA. MITOSIS
THE DIRECTION OF THE PREVAILING WINDS IS FROM WEST TO EAST.
2 PROTONS, 2 NEUTRONS, 3 ELECTRONS…WHAT IS THE CHARGE OF THE ION?
-1
IF THE EARTH IS TWO TIMES THE SIZE, AND THE DISTANCE TO THE MOON STAYS THE SAME—GRAVITATIONAL ATTRACTION WILL INCREASE!
