Answer:
Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).
Explanation:
Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.
The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.
The other options are not correct because:
<em> B. Master genes do not </em><u><em>determine the organization of the genome</em></u><em>
.</em>
<em> C. </em><u><em>Regulation of cell metabolism</em></u><em> depends of substances as hormones and enzymes.
</em>
<em> D. </em><u><em>The rate of translation</em></u><em> does not depend on the activity of master genes.</em>
Answer:
Covering organs within trunk cavities
Lining trunk cavities
Explanation:
Serous membranes are layers of tissue that protect the organs. They prevent the organs from getting damage from friction which can occur as they rub against the cavity walls.
Serous membranes have two layers, the visceral layer and the parietal layer. The visceral layer covers the organs while the parietal layer covers or lines the cavity walls. In between these two layers, you will find a gap or cavity filled with serous fluid.
They cover organs like the heart, lungs, blood vessels (some of them at least), testes and other organs found in the abdominal cavity.
