Answer:
All of the above.
Explanation:
Reflex arc may be defined as the neural pathway that control the function of the reflex system of the body. Two main types of reflex arc are somatic reflex arc and autonomic reflex arc.
The afferent neuron carries signal from the receptors to the integrating center via the interneuron. The efferent neuron carries signal from the integrating center to the effector organ via the inter neuron.
Thus, the correct answer is option (e).
 
        
             
        
        
        
A good extraction solvent should have a strong solubilizing capability for the compound of interest, it should be immiscible or only weakly misciblewith the matrix solvent ( the first solution or mixture containing the compound from its natural source, e.g., water/ether. water/ chloroform, etc. If possible the extraction solvent should be non-flammable, non-toxic or of low toxicity, reasonably volatile, and of low eco-impact. Inexpensive and available, of high purity , and shelf stable. If one is determining the compound of interest by UV/Vis spectrophotometry or fluorescence, the solvent should have extremely low absobance or emission at the wavelength of analysis
•	high solubility for the solute and low solubility for the carrier liquid.
•	density difference vs. the carrier liquid greater than 150 kg/m. ...
•	mid-level interfacial tension (5–30 dyne/cm)
•	high resistance to thermal degradation.
 
        
             
        
        
        
Answer:
B
Explanation:
The structure of the mitochondrion is key to the process of aerobic (in the presence of oxygen) cellular respiration, especially the Krebs cycle and electron transport.
 
        
                    
             
        
        
        
The air gap is filled with gas which increases the insulation between the glass pieces. Double glazed windows are highly efficient, reducing your heat loss or gain by up to 30% when compared to single-glazed windows.
