Answer:
a. RER, microtubules, cytoplasm
Explanation:
The axoplasmic transport or axonal transport that moves the material at the rate of 1-5 mm/day is called slow axoplasmic transport. This system serves to deliver the materials required for regeneration of axons and axoplasm. It includes the movement of proteins from cytoplasm along the axon.
On the other hand, the fast axoplasmic transport moves the material at the rate of 200-400 mm/day. It serves to transport integral membrane proteins and secretory proteins formed on RER. The fast movement occurs with the help of motor proteins that move the material along the surface of microtubules present in the cytoskeleton of neurons.
In waves because sound echoes. Waves are the only form of energy that can echo.
Answer:
Yes! The correct answer is smog production
Explanation:
Actually, Smog refers to heavily stagnant air formed by the mixture of nitrogen oxides with hydrocarbons released to the atmosphere from the exhaust of automobiles.
Thus, smog production is ABSOLUTELY A NON-ORGANIC process i.e it does not involve any activity of living organisms like microorganisms. So, all the processes mentioned above involved microorganisms EXCEPT SMOG PRODUCTION
