Q1. Johnny, a 5-year-old boy, has been growing by leaps and bounds; his height is 100 percent above normal for his age. He has been complaining of headaches and vision problems. A CT scan reveals a large pituitary tumour.
1) What is the possible cause of the excessive growth?
2) What condition will Johnny exhibit if corrective measures are not taken?
3) What is the probable cause of his headaches and visual problems?
Q2. Suppose the diameter of the field of vision in your microscope is 2mm under low power. If one Bacillus cell is 2 micrometers how many Bacillus cells could fit end to end across the microscope? How various 10 micrometers yeast cells could fit across the field?
