Also called simple sugars, they are the most basic units of carbohydrates
The correct answer to this is:
“the ependymal cells”
Glial cells are cells that sustain
and protect the neurons in the peripheral and central nervous system. They estimate
to take up about half the volume of the nervous system. One of the glial cells
is the ependymal cells. They create a
simple cuboidal to columnar epithelium which is known as ependyma.

its c
Explanation:
taxonomy is the science of naming, defining and classifying groups of biological organisms on the basis of shared characteristics.
Answer:
A. Prions do not contain genetic information, which is affected by ionizing radiation.
B. Denaturants may affect the tertiary structure of prions.
C. Prions are proteins.
Explanation:
Prions are the proteinaceous infectious particles that cause many degenerative diseases of neurons in both animals and humans. They consist of only protein and no DNA or RNA. Due to the absence of DNA or RNA as genetic material, these infectious particles are resistant to ionizing radiation. Ionizing radiations affect nucleic acids of pathogens to destroy them.
Denaturation of proteins affects their secondary and tertiary structures and leave them non-functional. Denaturation may be caused by changes in temperature, pH, disturbance of hydrogen bonds, etc. Therefore, to destroy prions, they need to be denatured.
