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.

Suppose that in unicorns, two autosomal loci interact to determine the type of tail. One locus controls whether a tail is presen
Nina [5.8K]

Explanation:

As you can see in the picture below, this is a dihybrid cross with a twist.

We can accomplish that mutually parentages are heterozygotes for both characters because the genotypes are  

9 unicorns with curly tails (shown in green)

3 with straight tails (shown in red)

3  curly tales trait carriers with no tail (shown in dark blue)

1  straight tail trait carriers with no tail ( shown in light blue)

If this was an ordinary case of the dihybrid cross, we would get a 9:3:3:1 phenotype ratio.

However, since the first trait, the presence of the tail, is affecting the other trait, the trait texture, the ratio is altered.

\frac{1}{4} of the offspring (genotypes tt C_   and tt SS) has no tail, therefore we cannot observe the texture of the tail (some of the tailless individuals have Curly alleles -blue squares marked with green, some of them have Straight alleles -blue square marked with red ).

Therefore, the altered ratio is  \frac{1}{2} curly tails,\frac{1}{4} straight tales, \frac{1}{4} tailless
