Answer to Question 1

ANS: D
With Wright stain, lysosomes are visualized as azurophilic granules.

Answer to Question 2

ANS: D
The genetically active portion of the nuclear chromatin, composed of DNA plus supporting proteins, appears diffuse and uncondensed and stains pale blue with Wright stain. It is also called euchromatin. Chromatin, which is condensed and stains darkly, is also called heterochromatin; it is the genetically inactive portion of the nucleus.

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.
