A typical human cell expresses only about 5% of its genes at any time. The expression of a gene can be regulated during any step

in the transition from a gene to a protein. In each step, there is a control point where the gene can be turned on or turned off. The gene expression can direct embryonic development during cellular differentiation in an embryo. The proteins responsible for the regulation are called

Answer:

Enzymes

Explanation:

The regulation of gene expression is the central dogma of life. It is a series or set of mechanisms in which genetic information in the DNA expresses in the form of RNA or protein. Cells give gene expression b different mechanisms as transcription, maturation of mRNA, and translation.

During these mechanisms, different gene-regulatory proteins are influenced. For example, a set of RNA polymerases that are proteins transcribe the DNA molecule during transcription. Transcription factors are also proteins that control the synthesis of proteins in the cell. These proteins are an enzyme that catalyse the gene regulation in the human cells.

Colorblindness is more common in males than in females because the allele for colorblindness is
Dafna1 [17]

Explanation:

It is sex-linked: genetic red-green color blindness affects males much more often than females, because the genes for the red and green color receptors are located on the X chromosome, of which males have only one and females have two.

Compared to a cell with few aquaporins in its membrane, a cell containing many aquaporins will A. have a faster rate of osmosis
Aloiza [94]

The correct option is A: have a faster rate of osmosis

A cell containing many aquaporins will have a faster rate of osmosis.

Aquaporins are micro water channels within the membrane that allow for the exchange of water and other neutral molecules over the biological membranes of other organisms.

Due to the presence of Aquaporins in plants, they have a high diversity of regulation properties, localizations, and transport selectivity.

The rate of osmosis increases as the aquaporins facilitate the transfer of water at a faster rate.

zhenek [66]

First, a complete digestive system means that the digestive tract has a beginning or the oral end and the opposite end or the aboral end. This is found in more complex animals starting from roundworms (flatworms have an incomplete digestive tract). A closed circulatory system is found in animals more recent than mollusks. The presence of the coelom makes it more evolved than the flatworms. 


Specifically, a small animal with a segmented body, short stiff appendages, and soft skin with the above characteristics point out to the phylum Annelida or annelids.
