You are in thhe middie of a tropical rain forest and it is very humid in the environment. You have a glass of nure water that vou have left outside for 2 davs. Nothing has come by to drink it and it has NOT rained either for those 2 das. You measure the amount of water in tite glass after these 2 davs and it is exactly at the same volume that was present 2 days before. #19- 25 19. In the above scenario, the outside environment is hypertonic to the water in the glass A) True B) False 20. In the above scenario, the outside environment is hypotonic to the water in the glass. A) True B) False 21. A diffusion gradient does exist in this scenario, but it is not very apparent. A) True B) False

how can we clasify clay is it organic or inorganic compound?

Amino acids polymerize in condensation reactions that result in the formation of an amide linkage (or peptide bond) between amino acid molecules. What dipeptide(s) may be formed in the reaction of glycine with phenylalanine?

4 How does aqueous Silver nitrate, AGNO3, works against neonatal conjunctivitis (inflammation of the outer eye) due to neonatal bacterial infection? It hydrolyzes protein in bacteria to amino acids and inactivate it. O It denatures the protein bacteria and kills them. It mutates the genetic make-up of bacteria and transforms them to useful proteins. It oxidizes side chains of cysteine residues to cystine.
