Research has discovered that for some individuals one challenge to maintaining weight loss is that after losing weight lipoprotein lipase activity in their adipose tissue is .

Low.

Explanation:

Lipoprotein lipase or LPL is an enzyme that hydrolyzes triglycerides of low density lipoproteins found in food, and breaks them down to free fatty acids and glycerol. Then they are released into muscle and fat tissue. Without this enzyme, the fat particles would accumulate in the blood. Particularly, lipoprotein particles called chylomicron transport dietary lipids from the intestines to other locations in the body. So these complex, lipids and chylomicron, accumulate in blood.

Fats are a type of nutrient obtained from food. It is essential to eat some fats, although it is also harmful to eat too much. The fats in food give the body the energy it needs to work properly. And, during exercise, the body uses the calories from the carbohydrates that have recently been eaten, but after 20 minutes, exercise then depends on the calories from fat to continue.

So, if the activity of this enzyme is high, the fat in the food is broken down and the person would not gain weight (always considering that there is a correct diet and exercise) On the other hand, if the activity of the protein is low, large amounts of fat accumulate in the blood.

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
