Order of Operations - ANS-PEMDAS
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
(between roots and exponents, do whatever comes first in the problem)
What is the easiest way to find a common denominator? - ANS-multiply all the
denominators
How do you multiply fractions? - ANS-multiply numerator x numerator
mutiply denominator x denominator
(don't need a common denominator)
how do you divide fractions? - ANS-flip the second fraction and then multiply
Z^-2 - ANS-1
---
zxz
perfect square number - ANS-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? - ANS-A (B+C) = AB + AC
what is the opposite of distributing? - ANS-factoring
what does the commutative property of addition and multiplication tell us? - ANS-order
does not matter
a+b=b+a
axb=bxa
, what does the associative property of addition and multiplication tell us? - ANS-grouping
does not matter
A + (B + C) = (A + B) + C
identity property of addition - ANS-any number + 0 equals itself
identity property of multiplication - ANS-any number x 1 equals itself
cerebral cortex - ANS-part of the nervous system; 4 lobes, spatial awareness,
consciousness, language, vision (thinking)
cerebellum - ANS-part of the nervous system; gray area in back, timing of motor
movement
brain stem - ANS-part of the nervous system; cord, life support, respiration, heartbeat,
active during sleep
digestive system - ANS-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
arteries
veins - ANS-take blood from the heart out to the body
take blood back to the heart
where are blood cells created? - ANS-in bone marrow
white blood cells
red blood cells - ANS-healers, help fight diseases
carry oxygen and nutrients
what is the key advantage of sexual reproduction? (as opposed to asexual
reproduction) - ANS-greater genetic variation (there can be many types of an organism)
how do the following plants reproduce?
algae
fungi
ferns
angiosperms
gymnosperms - ANS-algae - asexually
fungi - asexually
ferns - both asexually and sexually
