Use the models that you created in lesson 2, lab 1 to you answer the following question.
compare the surface area to volume ratio of a large cell to that of a small cell.

why does the ratio of surface area to volume increase with the decrease in cell size?

a. a larger cell has more surface area than volume.
b. a smaller cell has more surface area than volume.
c. a smaller cell has more volume than surface area.
d. a smaller cell has an equal ratio of surface area to volume

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.

Fruit bats in central america eat bananas and other fruits. banana plants rely on bats for pollination. what would be the most likely consequence on the banana crop if fruit bats were eliminated from the area? the banana crop would increase because bats would stop eating the crops. the banana crop would decrease because bats would no longer pollinate the crops. the banana crop would remain constant because bees would replace the bats. the banana crop would remain constant because the plants would adapt using asexual reproduction.
