Explanation:

Question 8

To determine the fitness zone, we refer to step - test heart rate norms for 17 - year - old females. Typically, a heart rate of 125 after a step test for a 17 - year - old female falls in the "good" fitness zone.

In the context of cholesterol, low - density lipoprotein (LDL) is known as "bad cholesterol" because it can contribute to the buildup of plaque in arteries. High - density lipoprotein (HDL) is "good cholesterol", lipid is a general term for fats, and lipoprotein is a particle that transports lipids.

Fibrin plays a key role in the blood - clotting process. Hemoglobin transports oxygen, white blood cells (and related components) destroy invading microorganisms, and certain immune cells or factors stimulate antibody production. Fibrin helps in forming a blood clot by creating a mesh - like structure.

C. good
