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>
The answer for the given question above is the second option. The statement that best describes a typical difference that could be found between the "Analysis" and "Conclusion" section of the lab report is this: Only the "Analysis" section includes specific data comparisons, and the only "Conclusion" section suggests further research. Hope this helps.
The answer is <span>d. homologous structures.
Homologous structures are </span><span>similar structures shared by different species. For example, the anatomy of joints in bones of birds and dinosaurs, support the idea that these two groups have a common ancestor. But since these two groups are different enough to be separated into different classes, it can be concluded that they evolved from the common ancestor.</span>
Answer:
C. Independent variable
Explanation:
The independent variable in an experiment is the variable that the experimenter manipulates or changes in order to effect a measurable response in the dependent variable.
According to this question, an experiment is conducted to determine what concentration of disinfectant is most effective in killing bacteria. The independent variable is the CONCENTRATION OF DISINFECTANT because it is the variable being changed or manipulated.
