Answer: The diffusion of ions along the axoplasm is faster,in myelinated compare to unmyelinated,
Neurons are the structural and functioning units of nervous system.They are the vehicles for transmission of impulses as electrical signals from one part of the cells,and from one part of the body to another.
The basic structural components of a typical neuron are the cellbody, the axon, and the dendrites.
Based on structure neurons are classified as myelinated and unmyelinated.This is based on the the surrounding layer of myelin sheath around the axon. The myelin provides the insulating layer for the axon.And ensures fast movement of impluses.
In myelinated neurons the myelin sheath are interrupted at intervals by gaps along the length of the axon called Nodes of Ranvier. These gaps contains more Na-K channels for influx and out-flux of K and Na+ ions for transmission of impulses.
The cytoplasm of axon is called axoplasm,Since this is surrounded by myelin sheath which contains Na-K+ channels,The rate of diffusion of ions along these channels is faster for depolarization to take place than in unmyelinated neurons. Inaddtion as these ions diffusion increases,its jump faster at the nodes of Ranvier (saltatory conduction) to the next axoplasm which further speed up the rate of transmission.
Unmyeinated lacks myelin sheath,therefore the exchange and the rate of diffusion of ions along the axons is low.

Doctors inject medicines in veins because veins are more accessible and donot have high pressure due to which there is no risk of blood backing up with into the infused fluid.
However there are some cases when medicine is injected in artery but a lot of precautions needs to be taken while doing so.
The given question is incomplete, the complete question is:
During germination, peas sprout and grow. The data table shows the carbon dioxide produced during the germination period of peas under different conditions. Condition Rate of carbon dioxide produced (mL/min) Germinating peas, 10ºC 0.01 Germinating peas, 20ºC 0.02 What is the best conclusion? The rate of cellular respiration in germinating peas is exactly one thousand times the rate of ATP production. Germinating peas at 10ºC create carbon dioxide at a rate of 0.01 mL/min during ATP production. Germinating peas at 20ºC have a higher rate of cellular respiration than germinating peas at 10ºC. The rate of cellular respiration cannot be measured without knowing the rate of ATP production.
Answer:
The correct statement is that at 20 degree C, the germinating peas exhibits a higher rate of cellular respiration in comparison to the germinating peas at 10 degree C.
Explanation:
The process of respiration results in the production of carbon dioxide, respiration refers to a chemical reaction that generates water, carbon dioxide, and energy by undergoing oxidation of the glucose molecules. This phenomenon plays an essential role in the life of the organisms for obtaining energy from the food they consume to perform daily activities.
From the question, it is evident that the peas, which were germinating at 20 degrees C exhibit a higher rate of cellular respiration as they are generating 0.02 milliliters of carbon dioxide in a minute, while on the other hand, the germinating peas at 10 degrees C are giving rise to 0.01 milliliters of carbon dioxide in a minute.
