Erin is only 17 years old and her total cholesterol is 600 mg/dl. why do you think her cholesterol is so much higher than the others in her family who have familial hypercholesterolemia?

Hypercholesterolemia can be defined as the genetic disorder in which the patient have abnormally high levels of blood cholesterol. The family of Erin suffers from familial hypercholesterolemia, so every member of the family have to take better care of what they eat, and exercise regularly to keep their cholesterol levels in check. All the members of the family are prone to high cholesterol levels as this is a genetic disorder. Erin probably does not pay attention to her diet and exercise and thus, she have such high levels of cholesterol as compared to her family members.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
