<span>A person who is ill with fever will experience an increased basal metabolic rate. The body’s metabolism contains all of the chemical and biological process needed for the conversion of food into energy and the use of it like digestion and excretion. So when we become sick, the metabolism speeds up to fight the illness.

Answer:
Transcription factors
Explanation:
This is because Eukaryotic gene expression is regulated by transcription factors and RNA processing, which occur in the nucleus, and during protein translation, in the cytoplasm.
Transcription in eukaryotic cells is controlled by proteins . These proteins then bind to some specific regulatory sequences and try to control the activity of RNA polymerase. The Gene expression is regulate by transcriptional regulatory proteins . Also ,the packaging of DNA into chromatin and methylatiin indicate levels of complexity to the control of eukaryotic gene expression.
The correct answer is D. to a mitochondrion.
<span>Cellular respiration is a four-stage process where a glucose molecule is gradually broken down into CO2 and H2O and some ATP is produced. The steps are:</span>
<span>1: Glycolysis- It occurs in the cytosol, glucose is Broken down into two molecules of pyruvate, ATP is made, and NAD+ is converted to NADH.</span>
2. Transition Reaction-Pyruvate is shuttled into the mitochondria and converted to Acetyl CoA for further break down pyruvate oxidation).
<span>3. The Krebs Cycle, or Citric Acid Cycle- Occurs at the mitochondrial matrix. The acetyl CoA goes through a cycle of reactions and as a result, ATP, <span><span>NADH and FADH2 </span>are produced, CO2 is released.</span></span>
<span>4.The Electron Transport Chain-Occursin the inner membrane of mitochondria, The NADH and <span>FADH2<span> which are made in other steps deposit their electrons in the electron transport chain, (becoming NAD and FAD). As electrons move down the chain, energy is released and used to pump H+ out of the matrix, forming a gradient for further ATP production (oxidative phosphorilation). </span></span></span>
