The main dietary factor associated with elevated blood cholesterol is saturated fat.
<h3>
What about saturated fat?</h3>
- Because they increase the amount of LDL cholesterol in our blood, saturated fats, sometimes known as "bad fats," increase the risk of cardiovascular disorders (including heart disease and stroke).
- Cholesterol that is circulated in the blood.
- The majority of this cholesterol is produced by the body, however some is also absorbed from the meals you eat.
- Even if they include fat, foods derived from plants never contain cholesterol.
- Only foods from animals do. Low density lipoproteins are able to transport cholesterol.
- Dietary fat, particularly saturated and trans fats, may increase LDL and total cholesterol levels in the blood.
- Blood cholesterol levels may be lowered by substituting polyunsaturated and monounsaturated fats, particularly olive and canola oil, for some saturated fats.
- When we consume too much saturated fat, the receptors stop functioning as effectively, and blood cholesterol levels rise.

Answer:
DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes.
Explanation:
The Cambrian explosion was a period at the Pre-Cambrian boundary of the geologic time scale at 542 Ma. At this boundary, the fossil record shows that animals suddenly appeared in a dramatic radiation of life. A radiation is the relatively rapid development of new types of organisms that derive from a common ancestor. The Cambrian explosion is important because it marks the origination of all major animal groups called phyla.
