Question

What is suspension?

Answer 1

A cloudy mixture of 2 or more substances that seperate when left alone

Answer 2

Elements - made up of only one type of atoms and cannot be broke down into something simpler Compounds - made up of 2 of more atoms

Answer 3

1. First letter always capital 2. Rest of the letters always lowercase 3. No periods at the end of the letters

Answer 4

The controlled flow of electrons through a conductor

Answer 5

The energy produced by the flow of electrons in a electric circuit

Answer 6

- source - load - conducting wires

Answer 7

Series = produces only one path for electrons to flow through Parallel = produces more than one path for electrons to flow through

Answer 8

Primary = cannot be reused must be replaced Secondary = can be reused more than once

Answer 9

Left slot = neutral Right slot = hot The bottom middle slot = ground

Answer 10

Ground fault circuit interruptor

Answer 11

The rate of electron flow in a circuit

Answer 12

The electric potential difference between two points in a circuit

Answer 13

The ability of a material to resist/oppose the flow of electrons in a circuit

Answer 14

The circuit will continue to flow electrons because there will be more paths for the electrons

Answer 15

The whole circuit will shut down because the only path will be interrupted

Answer 16

- Like charges repel - Unlike charges attract - A charged object exerts an electric force

Answer 17

1. Charge by contact (friction and conduction) 2. Charging by induction 3. Charging by conduction

Answer 18

Good conductors = silver, copper, gold Fair conductors = earth, salt water, carbon Good insulators = rubber, paper, plastic

Answer 19

Huge amount of static electricity

Answer 20

Atmosphere = the layer of gases of earth Biosphere = where life exists Hydrosphere = the water above and below Lithosphere = the rocky layer of earth

Answer 21

The study of animals and the non living parts of the environments

Answer 22

Biotic = all the living organisms in a ecosystem ex. Grass, skunk, worms Abiotic = all the non living things in a ecosystem ex. Water, wind, soil, air

Answer 23

Population = A group of Individuals in the same species living in the same Community = the interactions of different species living the the same area

Answer 24

Autotrophs = aka as a producer can make their own food Heterotrophs = cannot make their own food and must live off of other organisms

Answer 25

Carnivores = eats only animals Herbivores = eats only plants Omnivores = eats both plants and animals Scavengers = eats dead or decaying organisms

Answer 26

A series of predator and prey relationships that eat each other

Answer 27

Shows the feeding relationships in a community

Answer 28

Producer, 1st consumer, 2nd consumer, 3rd consumer, 4th consumer

Answer 29

1. Pyramid of numbers 2. Pyramid of biomass 3. Pyramid of energy

Answer 30

Mutualism = a relationship between two organisms where both organisms benefit Parasitism = a relationship between two organisms where one directly lives off another organism Commensalism = a relationship between two organisms where one organism benefits and the other one is unaffected Predation = a relationship between two organisms where one organism preys on or hunts/eats the other organism Competition = a relationship between two organisms where both are competing with each other for important resources Intraspecific = competition between same species Interspecific = competition between different species

Answer 31

- light energy - chemical energy - thermal energy - radiant energy

Answer 32

The process used by plants to turn light energy into chemical energy (carbohydrates)

Answer 33

The process by which organisms turn stored chemical energy ( sugar/glucose) Into usable energy for the cell

Answer 34

- water cycle - carbon cycle - nitrogen cycle

Answer 35

- malleability - lustre - ductility - texture - viscosity

Answer 36

- change in odour - change in colour - bubbles form - change in energy - precipitation forms
