Answer:( answer for number one) an essential nutrient for the production of amino acids, proteins, nucleic acids. ( number 2 ) for the growth, maintenance, and repair of all tissues and cells, and for the production of the genetic building blocks, DNA and RNA
The active site is <span> a site on the substrate molecule where specific enzyme molecules bind.</span>
A constitutive gene is unregulated, which means that its expression level is relatively constant. The expression of a
regulated gene varies under different conditions. In bacteria, the regulation of genes oftentimes occurs at the level
of transcription by combinations of regulatory proteins and small effector molecules. In addition, gene expression
can be regulated at the level of translation or the function of a protein can be regulated after translation is
completed.
<span>An inducible gene is a gene whose expression is either responsive to environmental change or dependent on the position in the cell cycle.</span><span>The rapid activation of gene expression in response to stimuli occurs largely through the regulation of RNA polymerase II-dependent transcription</span>
Precipitation<span> is </span>water<span> released from clouds in the form of rain, freezing rain, sleet, snow, or hail.</span>
A tiltmeter monitors the earth's crust to determine if any uplift is occuring. Simply put, it measures the crust to see if the elevation has changed.
