Answer to Question 1

ANS: B
S is the stage where DNA replication occurs. G1 is a period of cell growth and synthesis of components. M is mitosis. Stage G2 has tetraploid DNA and a large cell volume.

Answer to Question 2

ANS: C
When the lysosomal membrane is ruptured, its contents of hydrolytic enzymes are released into the cytoplasm of the cell and cellular organelles are damaged; this may result in the death of the cell.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
