What do you understand about foodborne illnesses?
A boy with colour blindness, has a mother with normal colour vision and a father with colour blindness. Did the boy inherit the gene for colour blindness from his mother or his father? Explain your answer to question 2a by using a Punnett square to identify the source of the colour blindness gene that was passed on to this boy.
Explain this type of heredity.
Dolphins and fish have similar body shapes. Is this feature more likely a homologous or analogous trait?
Explain your answer.
a. Analogous-Dolphins are mammals and fish are not, thus their evolutionary paths are quite separate. They have similar body shapes because of their similar environment.
b. Analogous-Dolphins and fish are both vertebrates, thus they share an evolutionary history, causing them to have similar body shapes.
c. Homologous-Dolphins and fish are both vertebrates, thus they have a similar recent evolutionary history, causing them to have similar body shapes.
d. Homologous-Dolphins are mammals and fish are not, thus their evolutionary paths are quite separate. They have similar body shapes because of their similar environment.

What are the constraints on the architecture of membrane-integral proteins that lead to the membrane-spanning regions of such proteins being less diverse in structure than soluble proteins?
A. Evolution of sense organ
B. Evolution of the heart and lungs
C. Evolution of cleidoic egg and internal fertilization
D. Ability to conserve water
E. Relatively waterproof skin.
Water potential is the pressure exerted by freely moving water molecules in a system. Describe the relationship between water potential with solute potential and pressure potential in plants.
Plant cell P has solute potential of -350kPa and pressure potential of 200kPa. Besides, is plant cell Q which has a solute potential of -500kPa and a pressure potential of 200kPa. Determine the direction of net movement of water between the two cells by using water potential equation.
Explain the characteristics of water that make it such an important medium for life. If an athlete was heavily perspiring after and intense match game, suggest one type of replacement drink ( with explanation) that he should take between hypertonic, Isotonic and hypotonic drink to recover himself.
