i remember there was another question about sea urchine and definition of ecosystem
but for ecosystem definition the answers were
a) producer eat upon on consumers
b) consumers have less energy that producers
c) producers have more bioms
D) and e) i do not remeber but there were something similar.
another bio question was about virous that i do not remember the question but the answers were interfron,intluken1 and 2 and some others ...
there was a question about how they calculate heart rate
i knew the answer from doing reading comp on one of topscores. i did not have any hormones question. i can kaplen bio was not helpful for this test.
i remeber i had another question regarding i think taking out the intestine of tadpole and add it to another frong and then what happens? some thing like that
as much as i looked at the schuam's book i found out if we know every thing in this book would help us alot for the test. this morning i noticed some thing really wierd. i was reading the schaum's on mandles' law i saw the same question about genotype of yellow, round that was on my test.
