Order of Operations
(between roots and exponents, do whatever comes first in the problem)
What is the easiest way to find a common denominator?
multiply all the denominators
How do you multiply fractions?
multiply numerator x numerator
mutiply denominator x denominator
(don't need a common denominator)
how do you divide fractions?
flip the second fraction and then multiply
z x z
perfect square number
Taking a positive integer and multiplying it by itself equals a perfect square.
Example: 3 x 3 = 9
9 is a perfect square.
what is the distributive property?
A (B+C) = AB + AC
what is the opposite of distributing?
what does the commutative property of addition and multiplication tell us?
order does not matter
a + b = b + a
a x b = b x a
what does the associative property of addition and multiplication tell us?
grouping does not matter
A + (B + C) = (A + B) + C
identity property of addition
any number + 0 equals itself
identity property of multiplication
any number x 1 equals itself
part of the nervous system; 4 lobes, spatial awareness, consciousness, language, vision (thinking)
part of the nervous system; gray area in back, timing of motor movement
part of the nervous system; cord, life support, respiration, heartbeat, active during sleep
salivary glands - produce saliva to get food down esophagus
esophagus - passageway for food
stomach - uses gastric acid and enzymes to break down food even more
pancreas - creates enzymes that stomach uses
small intestine - long, absorption of nutrients into body takes place here
large intestine - waste is collected
rectum - waste is released
take blood from the heart out to the body
take blood back to the heart
where are blood cells created?
in bone marrow
white blood cells
red blood cells
healers, help fight diseases
carry oxygen and nutrients
what is the key advantage of sexual reproduction? (as opposed to asexual reproduction)
greater genetic variation (there can be many types of an organism)
how do the following plants reproduce?
algae - asexually
fungi - asexually
ferns - both asexually and sexually
angiosperms (flowering plants) - sexually
gymnosperms (cone plants) - sexually
What evidence supports Darwin's theory of evolution (adaptation)?
categorizing living things
kingdom (least specific)
species (most specific)
What is the lifecycle of a butterfly?
1. egg - laid on a leaf on purpose
2. larvae or caterpillar - eat all day
2. pupa (cocoon) - metamorphasis
4. adult - butterfly, imago stage, only alive a few weeks and mate for most of it
What is the lifecycle of a frog?
2. tadpole (polywog) - gills and tail
3. tadpole with legs - back legs first then front
4. froglet - converts to breathing air, crawls onto land
5. adult frog - no tail
What is the lifecycle of a mouse?
mice are mammals and warm blooded, they look like their parent when they're born (as oppose to buttery or frog)
1. born without hair - deaf and blind
2. childhood - have hair, eat solid food
3. adults - reproduce
what is the opposite of photosynthesis?
-plants use a chemical called chlorophyll to absorb solar energy
-use a chemical reaction that creates carbohydrates
-plants take in water and carbon dioxide and get rid of carbon based nutrients and oxygen
animals and plants take in oxygen and break down carbohydrates, release the energy stored in their chemical bond
3 types of symbiosis
mutualism - mutually benefit
parasitism - host suffers
commensalism - host indifferent
examples of prime numbers
2, 3, 5, 7, 11, 13, 17, 19, 23
the answer to a multiplication problem
the answer to an addition problem
vacuole - holds waste
chloroplast - processes light energy from sun and converts into sugar for the plant to have energy
cell wall - thicker than in an animal cell, gives the cell structure
what is mitosis?
cell division - creates diploid cells
what is meiosis?
cell division - creates sex cells, haploid cells
pumps oxygen rich blood out to other parts of the body
parts of the heart
The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
The right ventricle pumps the oxygen-poor blood to the lungs.
The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
The left ventricle pumps the oxygen-rich blood to the body.
water moving across a permeable membrane from a place with more salt to a place with less salt.
what environmental factors affect plants?
how do we get our month system?
based on the moon's orbit around the earth
when the sun and the moon are in alignment, we get more extreme tides
when the sun and the moon are perpendicular, we get less extreme tides
how stars begin, as huge clouds of dust and other particles
when a nebula contracts and all the particles combine and ignite a nuclear reaction
life cycle of a star
adult star - becomes denser
collapses - into brown dwarf, white dwarf, neutron star, nova, or black hole
Hertzsprung Russell diagram of spectral class
shows the relationship between absolute magnitude, luminosity, classification, and effective temperatures of stars
the sun is the main sequence star
why do numerous bodies of the solar system orbit the sun?
because of centrifugal force
My - Mercury
Very - Venus
Excellent - Earth
Mother - Mars
Just - Jupiter
Served - Saturn
Us - Uranus
Nachos - Neptune
layers of the Earth
3 types of rocks
chemical - acid rain
physical - ice, wind, rain
use it to predict weather
low pressure generates storms
a positive or negative number and 0
counting numbers and 0
a composite number
numerator is bigger than the denominator
volume of a cylinder
πr2 x h
(radius x height)
what is an example of newton's third law?
an inflated balloon moves through the air when a jet of air leaves its neck as it deflates
Which chamber of the heart labeled in the
diagram above is primarily responsible for
pumping blood to most of the organs and
tissues of the body?
what is an example of cell division where the genetic material is halved?
a cell in the testes of a male sparrow divides and produces 4 sperm
the full moon is never in the sky at the same time as the sun
tile problem from practice test
find the factors for each side
the factors in common are the square sizes
√ (2 x 2 x 2) = 2√2
4, 9, 16, 25
(2x2) (3x3) (4x4) (5x5)
what percent of 8 is 2?
x/100 x 8 = 2
divides the angle into equal parts
ionic bonds in compounds
with a metal (sodium) and nonmetal (chlorine)
metallic ion gives up electron
nonmetallic ion takes electron
water pressure increases with depth
the deeper the water, the greater the pressure
whale and barnacle
egrets and rhinocerous
fungi and orchids
predator prey relationship - example
fox and chicken
how far back can you date something based on Carbon 14 half lives?
radioactive dating only works for 50,000 years
how would you date a moon rock?
by the ratio of radioactive potassium to argon
(based on the amount of radioactive material left)
what is the amount of increase of the energy released for every point on the richter scale?
31.7 times increase
so from 4 to 6 it's 31.7 x 31.7 since its a two point increase
weather in low pressure vs high pressure area
low pressure has poor weather
high pressure has improving weather
how much of the moon is lighted during the first and third quarter?
