High-density lipoproteins (HDL) refer to macromolecular complexes made up of lipids and that have the function of transporting dietary lipids to the liver.
<h3>What are lipoproteins?</h3>
They are macromolecules whose function is to package insoluble lipids in the aqueous medium of plasma and transport them from the intestine and liver to peripheral tissues and, from these, return cholesterol to the liver for elimination from the body.
<h3>Characteristics of High Density Lipoproteins (HDL)</h3>
- They are synthesized and secreted by the liver and to a lesser extent by the intestine.
- They transport cholesterol from peripheral tissues to the liver, this is known as “Reverse Cholesterol Transport”.
Therefore, we can conclude that lipoproteins are macromolecules whose function is to transport lipid molecules from one organ to another in the aqueous medium of plasma.

The correct answer is hyponatremia. This is also called water intoxication in athletes. Water is a substance that is devoid of any solutes and electrolytes. The major extracellular electrolyte sodium is present in the extracellular fluid and the plasma. In the event of increased water intake, the sodium in the plasma will be diluted hence will cause hyponatremia.
Answer:
Compare the carboniferous period to the Devonian period is compared below in details.
Explanation:
In the Devonian Period, woods and land plants developed and vertebrates performed their presentation. Four-legged vertebrates developed during the Carboniferous Period, which created an improvement in the number of land-based bodies. The climate of the continental inland sections was very heated through the Devonian Period and usually quite dry while woods and land plants developed during the Carboniferous period.
Answer: Microorganism activity affects soil acidity and the amount of organic matter in soil. It also affects the nutrient and mineral levels in soil as well as soil structure.
