How could a change in the DNA sequence of a single gene affect an organism?

Match the digestive enzymes to the macro molecules they to digest. down fats into glycerol and fatty acids down carbohydrates into simple sugars down nucleic acids into nitrogenous bases and simple sugars down proteins into amino acids

You have a solution that contains phospholipid vesicles in a test tube. these vesicles have phospholipid bilayers, but do not contain any membrane transporters. you add a number of different molecules to the solution, and wait a period of time for them to equilibrate. if you could measure the concentration of each molecule, for which of the following would you expect to measure equal concentrations inside and outside of the vesicles? assume for this question that the overall osmolarity inside and outside the vesicles is the same (that is, there is no appreciable diffusion of water across the membrane). (select two answers) an amino acid with a hydrophobic side-chain a small non-polar molecule a negatively charged ion a small polar molecule a small lipid hormone

Of seawater increases with decrease in the temperature. therefore, the cold water sinks to the deeper layers at the bottom
