Since we have finished our aquaponics our team has been testing the water for ammonia, nitrates, nitrites, and pH. In biology we have started a new section on deoxyribonucleic acid on the structure of dna, nucleic acids and bases. Making of rna, dna unwinds and complimentary rna bases are brought in, and form sugar-phosphate bonds, then the rna strand is released and the dna molecule rewinds. We are starting the study of evolution, and have done a natural selection handout on variations between mouse populations on the length of their tails.
