Woot I passed this test with a 90(recieved my grade today) and the thing is, most of you guys are in 9th grade, Im only IN 7th GRADE I messed up on a few questions: 1)The windmill question- this is wrong right?-Lessens CO2 and produces oxygen. 2)The fourth Question about The human liver contains many specialized cells that secrete bile. Only these cells produce bile because I put 3 3)Number 8 bout Which sequence best represents the relationship between DNA and the traits of an organism? I put 3 4)The puppies shown in the photograph below are all from the same litter. I put the selective breeding answer 5)The question about Dolly -_- 6)33, Pituitary Glands question. 7)Identify one event that could result in the virus changing to a form able to spread from human to human, Was it mutation or reproduction? 8)And the Solvent Question, I had NI(No idea) about this one.
