Answer to Question 1

ANS: B
Fibrinogen binds to the receptor GP IIb/IIIa. Membrane phospholipids supply arachidonic acid, which becomes converted to thromboxane during platelet activation. They form part of the platelet glycocalyx, which is the platelet surface. Many of the coagulation enzymes bind to platelet phospholipids, including factor IX, X, and prothrombin.

Answer to Question 2

ANS: A
Fibrinogen must bind to its receptor GP IIb/IIIa assembled on the platelet membrane after activation for normal platelet aggregation.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
