1. BIOLOGY EOC PRACTICE Q #1

2. 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)

3. BIOLOGY EOC PRACTICE Q #2

4. 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.

5. BIOLOGY EOC PRACTICE Q #3

6. 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
mRNA is produced in the nucleus during the process of transcription.

7. BIOLOGY EOC PRACTICE Q #4

8. 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

9. BIOLOGY EOC PRACTICE Q #5

10. 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)

11. BIOLOGY EOC PRACTICE Q #6

12. 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)
