Who is at the greatest risk of a heart attack? a. Forrest, who has high levels of LDLs and low levels of HDLs b. Sawyer, who has low levels of both LDLs and HDLs c. Gump, who has high levels of both LDLs and HDLs d. Tucker, who has low level of LDLs and high levels of HDLs

(C) Gump, who has high levels of both LDLs and HDLs

Explanation:

A high level of LDL is a threat to good health. It's an indicator to a bad level of cholesterol

A low level of HDL which indicates a low level of cholesterol is a good sign to health.

But when a person has a combination of High LDL and High HDL that's a sure chance of HEART ATTACK.

In other words,

Heart attack is highest if a person has level of LDL and High level of HDL

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive
