Human destruction
for farming in the fertile soil
Answer:
B) Viruses are killing some of his B cells and becoming incorporated into the genomes of others.
Explanation:
Epstein-Barr virus causes infectious mononucleosis by following mechanism.
1) Epstein-Barr virus attaches to and infects epithelium of the throat where it replicates and causes pharyngitis.
2) Virions enter the lymphoid vessels and are carried to the lymph nodes. Some virions escape the lymphnode trap and are carried to the bloodstream.
3) Virions attach specifically to B lymphocytes and infect them, producing either latent infection or productive infection.
4)The infected B lymphocytes actively replicate and differentiate into cells producing random immunoglobulins.
5)T cells respond to infection and destroy the lymphocytes replicating EBV vitus.
6) Latently infected B lymphocytes become immortal. They are not attacked by T cells.
Answer:
- Habituation.
- Sensitization.
- Classical conditioning.
- Operant conditioning.
Explanation:
Types of learning include habituation, sensitization, classical conditioning, operant conditioning, observational learning, play, and insight learning. One of the simplest ways that animals learn is through habituation, where animals decrease the frequency of the behavior in response to a repeated stimulus.
The primary function of the chloroplasts in a plant is to convert light
from the sun into glucose and energy in a process that is known as
photosynthesis. This energy is then used by the plant cells for
incredibly important functions such as growth and repair, so the chloroplasts are amongst the most necessary parts of any plant.
Answer:, facilitated diffusion differs from passive diffusion in that the transported molecules do not dissolve in the phospholipid bilayer. Instead, their passage is mediated by proteins that enable the transported molecules to cross the membrane without directly interacting with its hydrophobic interior.
