Answer:
The correct option is C. <u>Damage to myelination.</u>
Explanation:
Multiple sclerosis can be described as a disease in which a person's body destroys his/her own myelin sheath. Myelin sheath is a protective sheath that covers the nerves. Hence, the nerves are not able to conduct signals. As the body's own cells destroy the myelin sheath, hence multiple sclerosis is an autoimmune disease. Multiple sclerosis remains a deadly disease as the proper cure to it has not yet been found.
Answer:
c. Amount of primary production
Explanation:
Primary production refers to the amount of energy that is converted by organisms from the sun. That is, the primary production is understood as the efficiency of the conversion of energy to organic substances, from the reaction of autotrophic organisms, by solar or chemical energy.
With this concept we can conclude that primary production does not influence the richness and diversity of species, but rather influences the activity of an ecosystem that corresponds to the total amount of organic matter produced in grams over a certain environmental area.
Knowing proteases being essential for replication of a virus
would suggest the virus contains at least one polyprotein. The family of
reoviruses has dsRNA genomes that replicate from the template of only the
positive ssRNA strand which makes it a conservative replication process.
