Answer:
C. Molecular chaperones have been mutated.
Explanation:
In prokaryotes; transcription and translation occur consecutively. Protein doubling additionally happens following the translation. The heat stun proteins or molecular chaperones are imperative to assume a part in the appropriate collapsing of the protein. At high-ranging temperatures, the protein misfolding can be ascribed to a change in mutation of the molecular chaperones.
The invention of the electron microscope opened up many doors for biologists as it helped them to view and learn the appearance of cells and their sub-cellular structures
<h3>What is an electron microscope?</h3>
Electron microscope are microscopes which helps biologists to view the appearances of cells of organisms which cannot be seen with our nak -ed eyes.
Generally, electron microscopes:
- Uses a beam of accelerated electrons as its source of illumination
- Helps in obtaining high resolution images of biological and non-biological specimens.
- It is also used in biomedical research
In conclusion, electron microscope helps biologists to view, learn and to also understand the appearance of cells and their sub-cellular structures

Answer:
The preferable option will be - B.
B. juxtaglomerular complex.
Explanation:
The cells of the macula densa, the juxtaglomerular cells, and the extraglomerular mesangial cells together form <u>the juxtaglomerular complex or juxtaglomerular apparatus.
</u>
The given options were -
a. nephron loop (loop of Henle).
b. juxtaglomerular complex.
c. renal corpuscle.
d. filtration membrane.
e. afferent arteriole.
- The juxtaglomerular apparatus regulates the blood pressure and also regulates the filtration rate of the glomerulus.
