Answer:
D. Anterograde flow
Explanation:
Axonal transport is of 2 types:
- Anterograde: Transport material from the soma towards the axon.
- Retrograde: Transport materia from axon towards soma.
Pathology :
- Virus enters tissue from saliva of biting animal.
- Virus replicates in muscle near bite.
- Virus moves to peripheral nervous system to CNS.
- Virus ascends the spinal cord.
- Virus reaches brain and causes fatal encephalitis.
- Virus enters salivary glands and other glands and other organs of victim.
Hence,Rabies bypasses many immune system defenses by traveling in peripheral neurons to reach the CNS. While anterograde flow is NOT used by the rabies virus to reach the CNS
It is because cell a undergone anaerobic respiration, that occurs in the absence of oxygen, which produced lactic acid especially in human muscles, and because it's a incomplete oxidation of sugar, therfore the atp, which is a kind of store energy, is less.
However cell b undergone aerobic respiration, which produces water molecules. It occurs with the presence of oxygen, and its a complete oxidation of sugar, therfore it produces more atp.

No, but you can always turn to google, or ask a relative as they may be more experienced.
All living organisms have ways of maintaining homeostasis. They have mechanisms for controlling such factors as their internal temperature, water balance, and acidity. Homeostasis is necessary for normal life processes that take place inside cells.
