Question Answer
How to safely turn on a bunsen burner close airhole light fire on gas
3 Lab Safety Rules Tie Hair back no drinking or eating wear goggles
How do magnification work? Eyepiece x Lens
Equipment list Beaker Gauze pad Bunsen Burner Test tube measuring cylinder tripod conical flask evaporating dish
What are the magnifications of the objective lenses? Eye Piece? Eye Piece = 10 times Red = 4 times Yellow = 10 times Blue/Black = 40 times
You need this to reflect light onto the microscope Mirror
Bar Graph Used for displaying values for non-related variables
Line Graph Used for showing changes over time with one variable
The part you put your eye closest to Eyepiece
Something that can change Variable
This is where you put the specimen Stage
When you change one thing . . . causes another thing to change relationship
Where do you find E . Coli in your body? In the instestines
Where do you find E . Coli outside your body? Animals and water
What do bacteria need to grow? warm temperature moisture space nutrience
How long does it take bacteria to double? 15 minutes

Top , Left, Bottom
What do the cell wall in plant cells do? The cell wall support the tree and protect the plant from various things
What do vacuole do? Vacuole stores food or nutrient a cell might need to survive. OR store waste
What are atom made of? 99.9% Space
What is Mass number? It is the top number and it tells us the number of proton plus neutron.
What is atomic number? It is the number of neutron and located at the bottom of an element
Electron Configuration 1st shell = 2 2nd shell = 8 3rd shell = 8 4th shell = 2
At what temperature does the particles stop moving? -273'C
3 states of matter Solid Liquid Gas
Solid to Gas Sublimation
Temperature to turn glass to liquid 1320'C
LAW OF CONSERVATION OF ENERGY Energy cannot be destroyed nor created. It can only be transferred from one form to another.
Native not introduced, originally found in NZ, could have flown another country.
Introduced Brought from another country
Endemic Only found in NZ
Indigenous Originally found in NZ but other countries may also have it.
Darwin's Hypothesis 1 . More offspring are produced than will survive to adulthood. 2 . Not all individuals are the same - there is variation in a population. 3 . Some adaptations increase rates of survival. 4 . These adaptations can be passed to the next generations - they are heritable.
3 Types of Erosion Ice Water Wind
Why don't earth show any craters It's been eroded.
Order of EMS Radio wave Microwave Infra-red Visible Light UV ray X-ray Gamma Ray
Radio Wave Uses to transfer info from one point to another via Electromagnetic radiation
Microwave Will cook your food in minutes. Also used by astronomers to look at the structure of galaxies.
Infrared Night vision goggles that picks up heat emitted by our skin and objects with heat.
Visible Light Our eyes detect this. Fireflies, light bulbs and stars all emit this. What we see
Ultra Violet This is emitted by the sun and are the reason for skin tans and burns. Can cause skin cancer
X Ray A dentist uses this to image your teeth, and airport securities uses them to see through your bag, doesn't go through bones.
Gamma Ray Very high energy electromagnetic waves. Use to sterilize surgical equipment and to kill cancer cells.
Green + Red Yellow
Red + Blue Magenta
Blue + Green Cyan
Additive light Light source
Answers in front
Three structures that focus light rays entering Lens Cornea Aqueous/ Vitreous Humor
Three layers that make up the wall of an eyeball Sclera Choroid Retina
Refraction Bending of light
TIR If light coming exceeds a certain degree, it will be totally internally reflected.
Proteins are made of __ Amino Acid
Test for Starch Colour Iodine Bluey black colour
Test for Glucose Colour Blue Benedict's Solution Blue - green - yellow - orange - red
Test for Protein Colour Copper Sulphate, Sodium Hydroxide Purple
Test for Lipid Colour Meths Cloudy emulsion
MRSGREN Movement Respiration Sensitivity Growth Reproduction Excretion Nutrience
Lack of Vit C scurvy - swollen bleeding gums
Lack of Vit D Rickets- fractures and deformity
Lack of Iron Anaemia - deficiency of red blood cells
Lack of Calcium Osteoporosis - hallucinate, muscle spasm
No. of Incisor Function 8 Cut food
No. of Canine Function 4 Stabbing, rib meat

Enzymes for: Protein Fat Starch Protease Lipase Amylase
Things in mouth to break down food Saliva and Amylase
Things in stomach to break down food Protease
Things in Duodenum that breaks down food Protease, Bile, Lipase, Amylase
Function of Small Intestine Absorbs nutrience
Function of Large Intestine Absorbs water
Stimulants Caffeine Nicotine Meths
Deppresant Alcohol
Hallucinogen Marijuana LSD
Layers of teeth Enamel Dentine Pulp Cavity - Nerve endings, blood vessel
What does Cornea do Outermost transparent layer of eye. Begins Focusing
What does Pupil do? The opening in the iris through which light passes.
What does Iris do? The coloured portion of the eye that controls the size of pupil
What does lens do This structure changes shape to focus light on the retina
What does retina do? Contains sensory receptors for vision
What does ciliary muscle do? Controls shape of lens
Optic Nerve Carries impulses from eye to the brain.
Cone? detects colour
Rod? detect black and white
Vitreous humor? Helps the eyeball keep its round shape and prevents it from collapsing
sclera? Outer layer of the eye. Protects the eye and helps it keep its shape.
Aqueous humor? Fills space between the lens and cornea. Plays a part in focusing light ray.
