Look again at the two solutions in Figure 3.3. 1 At the start of the experiment, which solution has a higher
water potential?
2. Which solution is hypotonic and which solution is hypertonic?
3 When do the two solutions become isotonic? Do their water
potentials differ when they become isotonic? Why?
4 Study the figure below and arrange solutions A, B, C and Din
decreasing order of their water potentials.

Which type of scientific statement is defined as a hypothesis or group of hypotheses that can be accepted as true based on the repeated experimentation with similar results

You have just sequenced a new protein found in mice and observe that sulfur-containing cysteine residues occur at regular intervals. what is the significance of this finding? it will be important to include cysteine in the diet of the mice. cysteine residues are required for the formation of α helices and β pleated sheets. cysteine residues are involved in disulfide bridges that form tertiary structure. cysteine causes bends, or angles, to occur in the tertiary structure of proteins.
