Answer: Guidelines

Explanation:

4.  A goal to help you improve academically and personally could be to take 30 minute breaks every hour or so while doing school work. Taking breaks every now and again to stretch, eat, move around, and breathe allows you to relax a little and refresh yourself. This improves your mood and understanding, as well as your ability to continue working and to succeed.

b. the activity of lipoprotein lipase.

Explanation:

Lipoprotein lipase (LPL) is considered or known to be a rate-limiting enzyme that hydrolyzes circulating triglyceride-rich lipoprotein such as very low density lipoproteins and chylomicrons.

It is known that the Lipoprotein lipase is  activated by glucagon and adrenaline. And this why the activity of LPL increases in muscle tissue and decreases in adipose tissue, during fasting while , its activity decreases in muscles tissue and increases in adipose tissue.

It is known that, it  plays an important role in breaking down fat in the form of triglycerides, which are carried from various organs to the blood by molecules called lipoproteins.

In conclusion, women fat cells in the breasts, hips, and thighs produce abundant LPL, storing fat in those body sites  , while in men, fat cells in the abdomen produce abundant LPL.
