Answer to Question 1

C

Answer to Question 2

Should include some variation on the following:
(a) recognize that Newton's second law describes the relation between the net force acting on an object, the object's mass, and its acceleration (i.e., Force = mass  acceleration).
(b) equate the two expressions (mass  acceleration = G M1 M2 / d2).
(c) identify which object each variable relates to (Mass of astronaut  acceleration of astronaut = G  Mass of Earth  Mass of astronaut / distance2)
(d) solve the equation for the acceleration of the astronaut (acceleration of astronaut = G  Mass of Earth / distance2)

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).

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.
