Answer:

By lowering the levels of total cholesterol and low density lipoprotein (LDL)

Explanation:

Dietary fibers are classified into two: the soluble fiber and the insoluble fiber. Studies have show that the soluble fiber play a significant role in lowering blood cholesterol, hence reducing the cardiovascular diseases.

Soluble fiber helps to lower blood cholesterol by its ability to bind to the small intestine which further binds to cholesterol most especially the ad cholesterol (low density lipoprotein). Binding of Fibers to cholesterol prevents them from migrating to the blood stream and to other  parts of the body. Since cholesterol can't get into the bloodstream, it exits the body through feces. Fiber has more effect on lowering LDL (bad cholesterol) than High density lipoprotein (good cholesterol.

Dmitry [639]

Answer:

False

Explanation:

In the genetic code, each triplet of nucleotides (i.e., each codon) determines one specific amino acid or one-stop codon. The genetic code is not overlapping, which means that the same letter in the genetic code (nucleotide) cannot be used for two different codons. There are 64 possible combinations of triplets of nucleotides, 61 of them determine amino acids, while three triplets determine stop codons (UAG, UAA, and UGA) that indicate the termination of translation. Moreover, the genetic code is also degenerate, which means that one amino acid can be coded by more than one codon.

Which of the following is an organism whose cells each contain a membrane<br> bound nucleus?
DerKrebs [107]

Answer:

D. Eukaryote

Explanation:

An organism that has membrane-bound organelles will have more complex organelles like mitochondria, Golgi apparatus, and ER. These are known as Eukaryotes. Additionally, they will have a nucleus that has the DNA coiled inside. Prokaryotes do not have membrane-bound organelle and the DNA floats in the cytoplasm. Most plants and animals are eukaryotes and all multicellular organisms are too.
