In radiology and nuclear medicine, single - photon emission therapy (PET)/computed tomography (CT) scanning is now a standard practice.
<h3>What distinguishes a CT scan from a PET scan?</h3>
The internal organs and tissues of your body are depicted in great detail by a CT scan. A Pet / ct can be more accurate than some other imaging procedures and can detect aberrant activity. Additionally, it can cause your body to alter sooner. PET-CT scans are used by doctors to reveal more details about the cancer.
<h3>What distinguishes an MRI from a PET scan?</h3>
Radio waves and magnets are both used in magnetic resonance imaging (MRI) studies. Both generate static photos of the body's organs and skeletal system. Using a radioactive tracer, PET scans can demonstrate how an organ is working in real time. CT and MRI scans cannot identify cellular responses in tissues and organs as early as PET scan images can.

Expression can be influenced by factors that are not genetic.
<h3>What are non-genetic factors?</h3>
Factors that are not part of a person's genetic make-up are referred to as non-genetic factors. These elements include aspects of the surrounding environment as well as aspects of an organism's lifestyle that contribute to its makeup.
It has been demonstrated in a number of studies that the formation of some features is influenced by both hereditary and non-genetic variables.
In the situation described above, both of the monozygotic twins have diabetes, but the lifestyle choices made by one of them causes the condition to manifest itself seventy percent of the time. It's possible that the person is drinking more alcohol and eating more sugar.

Answer:
<em>a </em><em>buffer</em><em> </em><em>is </em><em>a </em><em>solution</em><em> </em><em>that </em><em>helps </em><em>to </em><em>resist </em><em>sudden</em><em> </em><em>changes </em><em>in </em><em>the</em><em> </em><em>PH </em><em>.</em><em>buffers </em><em>are </em><em>important</em><em> </em><em>in </em><em>living</em><em> </em><em>organisms </em><em>because</em><em> </em><em>most </em><em>biochemical</em><em> </em><em>processes </em><em>proceed </em><em>normally </em><em>only </em><em>when </em><em>the </em><em>PH </em><em>remains </em><em>within</em><em> </em><em>a </em><em>fairly </em><em>narrow </em><em>range.</em><em>.</em><em> therefore</em><em> </em><em>buffers </em><em>are </em><em>commonly </em><em>used </em><em>in </em><em>living</em><em> </em><em>organisms </em><em>to </em><em>help </em><em>maintain </em><em>a </em><em>relatively</em><em> </em><em>stable </em><em>PH.</em>

Answer:
c. Minimum amount of energy for the reaction to occur
Explanation:
The "energy of activation" or <em>"activation energy"</em> refers to the minimum amount of energy for the reaction to occur or the<u> minimum amount of energy needed for molecules to go through a chemical reaction.</u> It is commonly measured in J/mole<em> (Joules per mole).</em>
The activation energy was termed by Svante Arrhenius, a Swedish scientist. He also developed a formula in order to show the relationship between the activation energy of the chemical reaction and its rate. He proved them to be indirectly proportional. The higher the activation energy, the lower the chemical rate.
