Law of conservation of mass?
It shows that no matter can be destroyed- it can change state though.

SALT characteristics of a plane mirror?
S- Same size
A- Upright
L- Same distance
T- Real
What is each line in a climatograph for?
Red line graph= average monthly temperature
Blue bar graph= average monthly precipitation
What is synthesis?
What is a reaction in which two or more elements or compound combined to form a single compound.
Components of the cell theory
Law of Reflection
The incident ray reflected rat and normal always lies on the same plane.
The angle of reflection is equal to the angle of incidence
Ways to classify climate?
Climate zones, the Köppen climate classification system, biome, ecozone, ecoregion
Balance this equation: __NaBr₂+__Cl₂--> __NaCl+__Br₂
What is 2NaBr₂+__Cl₂--> 2NaCl+2Br₂
Role of the epiglottis?
Prevents food from entering the trachea
What is Hyperopia and how is it corrected?
Distinguish between weather and climate
Weather: weather is a set of environmental condition encountered from day to day
Climate: climate is the set of environmental conditions averse over years in a specific region
How To Name Ionic Compounds
Write down the name of the metal first
Write down the non-metal second and change the ending to “-ide”
See chemical process- reference sheet (table 2)
Describe Anaphase
Spindle fibers begin to shorten and contract
Centromeres are separated
Each chromosome split into two sister chromatids
The two chromatids move to opposite ends (poles) of the cell
Single-stranded chromes start to uncoil into thin strands of chromatin
What is the Iris and what is its function?
The coloured portion of the eye; circular band of muscle; controls the size of the pupil and so it controls the amount of light that enters the eye.
Albedo?
A measure of the percentage of light that on object reflects.
How To Name Molecular Compounds
Names of molecular compounds often contain prefix
Prefixes are used to indicate the # of atoms present in each element
See chemical process- reference sheet- table 5
First non-metal-use prefixes except for mono-
Second non-metal uses prefixes all the time and change ending to “-ide”
Respiratory Structures In Order
Determine the index of refraction or speed of light in different media.
N=c/v
N= index of refraction (no units)
c= speed of light in a vacuum
v= speed of light in a medium
We can determine the previous climate through tree rings. If the gap between each ring is small, then it was a dry year. If the ring is big, it was a wet year. If it is dark, it means there was a forest fire.
