Question 2

Rheumatic fever (RF) is an inflammatory disease following infection from Streptococcus bacteria. It mainly affects children between ages 5 and 15 and occurs approximately 20 days after strep throat or scarlet fever. Severe RF can result in degeneration of the heart valves. Based on this scenario, RF is most likely to cause

Accepted Answer

A)  lose more iron (during menstruation). 
B)  have a smaller volume of blood. 
C)  have less bone marrow. 
D)  eat less red meat than males. 
E)  have fewer red blood cells. 
A)  lose more iron (during menstruation). 
B)  have a smaller volume of blood. 
C)  have less bone marrow. 
D)  eat less red meat than males.

Question 8

Based on this figure, which of the following is TRUE?

Accepted Answer

A)  Oxygenated and deoxygenated blood mix in the atria. 
B)  Oxygenated and deoxygenated blood never mix. 
C)  Oxygenated and deoxygenated blood mix in the ventricle. 
D)  Deoxygenated blood enters the body capillaries after being pumped from the heart. 
A)  Oxygenated and deoxygenated blood mix in the atria. 
B)  Oxygenated and deoxygenated blood never mix. 
C)  Oxygenated and deoxygenated blood mix in the ventricle. 
D)  Deoxygenated blood enters the body capillaries after being pumped from the heart.

Question 9

Southern Copperhead snake venom contains a protein called disintegrin. Disintegrins bind to a class of membrane receptors called integrins. Platelets use integrin receptors to aggregate at a site of tissue damage. Why does the snake venom contain this molecule?

Accepted Answer

A)  The molecule helps kill the snakeʹs prey by producing large clots that travel in the body and produce heart attacks and strokes. 
B)  By binding to the platelets, the molecule inhibits the formation of fibrin. 
C)  The molecule interferes with clot formation so that the venom can travel more efficiently from the site of the bite to the rest of the body. 
D)  After the snake bites its prey, the molecule helps in wound healing.
