Answer to Question 1

At convergent plate boundaries, mountains form from crustal thickening and uplift by compression. Mass is also added by volcanic and plutonic rocks.

Answer to Question 2

Flexural isostasy describes the bending of a strong crust above a high-viscosity mantle. The Pratt and Airy models assume the crust is weak, with a low-viscosity mantle, so once glacier ice melts, the crust quickly responds. Glaciers are good examples of isostatic adjustment. The glacier adds mass, which causes subsidence of the crust below the mass, and mantle flowing away from the depression causes a small bulge adjacent to the region of subsidence. Melting removes mass and the crust returns to approximate its pre- glaciated position.

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).

About 80% of major fungal systemic infections are due to Candida albicans. Another form, Candida peritonitis, occurs most often in postoperative patients. A rare disease, Candida meningitis, may follow leukemia, kidney transplant, other immunosuppressed factors, or when suffering from Candida septicemia.

A serious new warning has been established for pregnant women against taking ACE inhibitors during pregnancy. In the study, the risk of major birth defects in children whose mothers took ACE inhibitors during the first trimester was nearly three times higher than in children whose mothers didn't take ACE inhibitors. Physicians can prescribe alternative medications for pregnant women who have symptoms of high blood pressure.
