BIOLOGY EOC
PRACTICE Q #1
Choice C is correct!
Feedback Loops..
Positive Feedback ENHANCES a condition. For
example:
 If polar ice melts then dark ocean water can heat up, so
more polar ice melts, so ocean water heats up more, and so
on….
Negative Feedback REVERSES a condition. For
example:
 You are hot; you sweat and it cools your body..
 You are hungry; you eat and you are no longer hungry…
 You are thirsty; your urine is dark yellow and not much in
volume (your body is conserving water)

PRACTICE Q #2
Choice C is correct!!
• ATP (adenosine triphosphate) is the energy
used by ALL living cells.
• ATP is used by cells to do all cell processes
(grow, move, repair, reproduce, etc.).
• Cells obtain ATP through the process of
CELLULAR RESPIRATION (when they break
down glucose). CR releases CO2 and H20, but,
most importantly, generates ATP.

PRACTICE Q #3
The correct answer: CCG GUA
• DNA is composed of sugar, phosphate and base.
• Bases are Adenine (A), Thymine (T), Guanine (G)
and Cytosine (C)
• Remember the DNA base pair rules:
– A with T
– G with C
• However, in RNA, there is no Thymine. So your
RNA base pair rules are:
– A with U
– G with C
• mRNA is produced in the nucleus during the
process of transcription.

PRACTICE Q #4
Choice A is correct!!
• DNA similarities are the STRONGEST evidence
for relatedness between organisms.
• Other evidence includes:
– Structural similarities
– Similarities in embryological development
– Fossil record
– Similar geographical distribution

PRACTICE Q #5
Choice D is correct!!!
• Large wings (L) is dominant to small wings (l)
• Yellow wings (Y) is dominant to white wings (y)
• A small white winged moth (llyy) mates with a
small white winged moth (llyy)
• llyy x llyy can ONLY produce llyy babies.
• Therefore, 100% of the offspring will be small
and white winged (llyy)

PRACTICE Q #6
Choice C is correct!!
• Sustainable means to consider the environment,
society and economy when making decisions.
– Fossil Fuel use is not good for the environment due to
the CO2 emissions.
– Refrigerators manufactured in other countries
requires shipping, which uses fossil fuels and results in
CO2 emissions. It would be better to buy local!
– Cutting trees from old growth forests is harmful to the
environment (and society since we lose places of
beauty and recreation)
