Question 6 *

Membrane-bound organelles have been an important component in the evolution of complex, multicellular organisms. Which of the following best summarizes an advantage of eukaryotic cells having internal membranes?

(A) Eukaryotic cells are able to reproduce faster because of the presence of organelles.

(B) Some organelles, such as mitochondria and chloroplasts, are similar to prokaryotic cells in structure.

(D) Compartmentalization leads to a higher mutation rate in DNA, which leads to more new species.

Question 7

Question 7 *

Simple cuboidal epithelial cells line the ducts of certain human exocrine glands. Various materials are transported into or out of the cells by diffusion. (The formula for the surface area of a cube is 6 * S2, and the formula for the volume of a cube is S3, where S = the length of a side of the cube.)Which of the following (look up) cube-shaped cells would be most efficient in removing waste by diffusion?
