Answer:
Neuronal polarity refers to the asymmetrical distribution of cellular components within a neuron. ... During neuronal polarization, a group of molecules work in concert to regulate the dynamics of the cytoskeleton. The cytoskeleton dynamics is essential for neurite extension and axon and dendrite formation.

Answer:
C₂H₄
Explanation:
A hydrocarbon with a double bond is called an alkene. The general formula for an alkene is CₙH₂ₙ where as the n represents the number of carbons.
Taking your problem as an example:
C₂H₄ has 2 carbons, as indicated by the subscript beside the chemical symbol of Carbon.
if C = 2 then n = 2
CₙH₂ₙ = C₂H₂₍₂) = C₂H₄
Fossils help scientists date rocks: True
Sometimes younger rock layers are found beneath older rock layers: True
The map of earth has changed over millions of years, but it is now set: False
No fossils from the precambrian era have been found because there were no organisms that time: False
hope these are correct :)
