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.
The brain's suprachiasmatic nucleus regulates the body's circadian rhythms. The suprachiasmatic nucleus is a minute region of the brain located in the hypothalamus above the optic chiasm, the circadian rhythm is the 24-hour cycle of organisms, related to sunlight and temperature.
<span>Somatic mosquito cells have 6 chromosomes. Its gamete has 3 chromosomes.
</span>
Mosquitoes have 6 number of chromosome but when mosquitoes<span> make sperm or egg </span>cells<span>, meiosis reduces the </span>chromosome<span> number to 3.
</span>
*the chromosome number in somatic body cells of a mosquito --- 6.
<span>the haploid (n) number is 3.
the diploid (2n) number is 6.</span>
