ArbitrLikvidat [17]
The two-word system that was developed by Carl Linnaeus for naming an organism is called binomial nomenclature.

Cite the most common molecular explanations for dominant and recessive alleles.
tangare [24]

Answer: Dominant allele codes for a functional protein. Recessive allele codes for a less functional or nonfunctional protein, or it does not code for any protein.

Explanation:

Alleles are different forms of a gene. There are two types, dominant and recessive allele. Heterozygous organisms have one of each, and the dominant allele is expressed. Homozygous organisms have either two dominant alleles or two recessive alleles.

<u>A dominant allele produces a functional protein</u>, even in the presence of a recessive allele, because only one copy of the allele is enough and it masks the effects of the recessive allele. This dominant trait is shown in individuals who are homozygous dominant or heterozygous,

<u>A recessive allele produces a less functional or nonfunctional protein, or it does not code for any protein at all.</u> A recessive allele does not become a trait unless both copies of the gene are present.

Ion channel gates close the pores of some ion channels in response to
Evgen [1.6K]

Answer:

All of the above

Explanation:

The ions present in our body can move through voltage gated ions channels present in the cell. The ions are unequally distributed in the interior and exterior of the cell.

The ion gated channel may get open or close depending upon the presence of the different ions. These ions movement changes the electric potential of the cell. The ions movement results in the propagation of the nerve impulse and may cause the cell membrane stretching. The binding of the molecules to the ion channels may open or close the movement of particular ions.

Thus, the correct answer is option (d).

What blood cholesterol carrier is of greatest concern in atherosclerosis? hdl vldl ldl?
blondinia [14]
The answer is LDL (Low Density Lipoprotein)

Arteriosclerosis is the build up of cholesrol on the inner walls of the arteries. In the long run, arteriosclerosis reduces the diameter of the blood vessels, causing high blood pressure. 
The endothelial cells of arteries have receptors that facilitate binding and transportation of the LDL hence facilitation of their accumulation in the blood vessels.
