Ecology
What is a biotic and abiotic factor?
Biotic factors are the living things within an ecosystem, Abiotic factors are the non-living things.
What charges do neutrons, electrons and protons have?
N = Neutral. E = Negative. P = Positive.
What is the unit for resistance?
Ohms
What is the largest planet in our solar system?
Jupiter
What does WHMIS stand for?
Workplace Hazardous Materials Information System
What is carrying capacity?
The maximum population size of a biological species that can be sustained by that specific environment.
Name two groups of elements on the periodic table:
Ex: Halogens and Nobel gases
In which type of circuit are these formulas true (Series or parallel?)
IT = I1 = I2 = I3 VT = V1 + V2 + V3. RT = R1 + R2 + R3.
Series
Which planet is furthest from the sun?
Neptune
What does HHPS stand for?
Household Hazardous Product Symbols
What is a population?
The number of living things within one certain habitat
Who invented the periodic table?
Dmitri Mendeleev
If one light went out in series, what would happen VS in parallel? Why?
In series, all lights would go out because they follow one path. In parallel, assuming the light doesn't block multiple paths, they wouldn't go out because they follow multiple paths.
What is the difference between a meteor and a meteorite?
Meteors burn up in our atmosphere to become "shooting stars", meteorites are meteoroids that make it to earth's surface.
The transition of a solid directly to a gas.
If a secondary consumer went extinct in a food web, what would happen to the primary and tertiary consumers?
The primary consumers would have a population increase since there's nothing eating it, and the population of the tertiary consumers would decline since it would not have anything to eat.
How do you calculate neutrons, and what are valence electrons?
Neutrons = mass - atomic number. Valence electrons are the electrons on the outermost shell of an atom.
What is a load?
A resistor or any other device that transforms electrical energy into heat, motion, sound, or light.
Which planet has the shortest year, how do you know?
Mercury, because it orbits closer to the sun than any other planet.
Name 5 WHMIS symbols.
Ex: Corrosive, Flammable, Harmful, Harmful or Fatal, Explosive, etc
What does bioaccumulation stand for?
The process by which toxins are passed from one trophic level to the next.
To become like a noble gas, atoms must lose or gain electrons by cooperating with another atom that also needs to lose or gain electrons. If they have the right amount of electrons to fill one of the atoms, and empty the other's outermost shell, what do you get once you complete this process (hint: ..... compound)
ionic compound
Which direction do electrons start from when flowing through a battery/cell?
They will start at the positive end and move towards the negative end.
Name the planets in order of decreasing size.
Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars and Mercury.
What's a solute and solvent?
Solute is the substance being dissolved, solvent is the substance making the other substance dissolve.
