Answer:
Rabies illustrates a negative consequence to otherwise healthy retrograde flow within axons. Which of the following components will not be involved in retrograde flow?
(i) Kinesin
(ii) Axon hillock
(iii) Neuronal cell body
(iv) Axoplasm
(i) Kinesin
Step-by-step explanation:
Description of the functions of the other options
Axon hillock
axon hillock or initial segment is the region where the nerve impulses are generated by the plasma membrane
Neuronal cell body
survival signals are carried by retrograde transport from the synapse back to the cell body, such as the TRK (tyrosine kinases), the nerve growth factor receptor.
Axoplasm
Axonal transport, or axoplasmic flow, or axoplasmic transport is a cellular process that is responsible for the movement of synaptic vesicles, lipids, mitochondria and proteins both towards and away from the cell body of a neuron, via the cytoplasm
Kinesin
A kinesin is a protein that belongs to a family of motor proteins present in eukaryotic cells.
The second one or the third one hope that help a little bit
Answer:
1/2
Step-by-step explanation:
Find two points on the line
(2,0) and (4,1)
The slope is given by
m= (y2-y1)/(x2-x1)
=(1-0)/(4-2)
= 1/2
Answer:
D
Step-by-step explanation:
the figure is composed of a rectangle and a right triangle ( top )
calculate the hypotenuse h of the right triangle using Pythagoras' identity
h² = 6² + 8² = 36 + 64 = 100 ( take square root of both sides )
h = 
= 10
the base of the rectangle is equal to h , then perimeter (P) of pentagon is
P = 10 + 4 + 6 + 8 + 4 = 32 cm
