Basically, it's the hardest test you'll ever take in your life
But I'm hoping that I can do good and qualify for the Semi-Finals...and then maybe Nationals!

As some of you may know, I'm trying to pursue a career in Biology and/or music, so doing well on this test can open up some serious doors for me
Here's some questions from the Bio Olympiad Practice Test:
Five events occur in a cell constituting a cause-and-effect sequence:
1. an enzyme is manufactured at the ribosomes
2. cellulose is deposited in a cell wall
3. a molecule of RNA is transcribed
4. a carbohydrate polymer is synthesized
5. a nucleic acid migrates from nucleus to ribosome
The order in which these events occur is:
A. 1,3,5,4,2
B. 2,1,4,5,3
C. 3,5,1,4,2
D. 4,2,1,3,5
E. 5,3,4,1,2
When bacterial cells multiply maximally during the logarithmic phase, the total number of cells (b) after some time interval (t) is equal to the original number of cells (B) multiplied by 2^n, where n is the number of generations formed during the time interval: n=t/g and b=(B)(2^n). The generation time (g) for type A cells is 28 minutes (assume no cell death).
Estimate the LEAST amount of time required for a population of type A cells to increase by 300 percent.
A. approx. 42 minutes
B. approx 48 minutes
C. approx. 52 minutes
D. approx. 58 minutes
E. more than 62 minutes
If a mouse is exposed to cycles of 12 hours of light followed by 12 hours of dark, the mouse is mostly active in the dark and has a rest-activity cycle of 24 hours. If the mouse is then kept in a constantly dark environment, the period of the rest-activity cycle is slightly less than 24 hours. Why does the mouse's cycle shorten in the dark environment?
A. the mouse's clock genes get harmful mutations
B. the mouse's circadian clock required environmental cues to reset it
C. the mouse's circannual rhythm is inhibited
D. the mouse's pineal gland secretes too much melatonin
E. the mouse's suprachiasmatic nuclei are over-stimulated by the darkness
The test is 50 questions of that crap!!
wish me luck
