Answer:
D) They can increase the reaction rate for a given reaction by a thousand-fold or more.
Explanation:
Enzymes are like catalysts with the only difference that they are bio-molecules. Biochemical/chemical reactions are slow because of 'transition state barriers' which require a lot of energy to overcome so enzymes rather than overcoming transition state barrier provide an alternate pathway for biochemical reactions which require comparatively less energy. Thus presence of an enzyme leads to an increase in reaction rate because alternate pathway which requires less energy makes the rate of chemical reaction rapid by a thousand-fold or more.
There are several examples that can be used as an implied power of Congress. The action that is a correct example, out of the choices given, is establishing the bank of the United States. The correct answer is B.
The Foramen (Meaning Opening) Magnum (Meaning Large) is a large opening at the base of the skull that the spinal cord passes through to connect the lower body to the brain. The Foramen Magnum is<span> one of the several foramina found in the base of the skull.</span>
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>
