<span>The right answer is: they work by blocking sodium channels in the cell membrane.
These drugs are used systemic and not local.
</span>they block sodium channels in the cell membrane in the synapses between neurons, and not along axons.
Many drug acts by blocking sodium channel, in a specific location, like antiepileptics in the nervous system, and digoxin and antiarrhythmic in the heart.
Answer:
Both extract from the soil while difference in their extraction method.
Explanation:
Harvesting food crops similar to mining because both are gained from the soil whereas it is also different from mining due to their method of extraction. Seeds are grown again and again in the soil and other agronomic activities has to be done to gain good yield of the crops while on the other hand, in mining precious metals is to be extracted that is already present in the soil.
<span>In their book "Interaction between temperament and environment" behavior geneticists Robert Plomin and Denise Daniels state, "Two children in the same family are [apart from their shared genes] as different from one another as are pairs of children selected randomly from the population." There may be many reasons children in the same family are so different from one another but their finding boils down to the environment. To a large extent the environment influences personality, psychopathology, and cognitive abilities. Environmental differences between children in the same family represent the major source of character and environmental variance.</span>

Answer:
Respiratory System: The respiratory system's main job is to move fresh air into your body while removing waste gases.
Nostril: To warm air on inhalation and remove moisture on exhalation.
trachea: Serves as passage for air, moistens and warms it while it passes into the lungs, and protects the respiratory surface from an accumulation of foreign particles.
bronchiole: To deliver air to a diffuse network of around 300 million alveoli in the lungs.
alveoli: To exchange oxygen and carbon dioxide molecules to and from the bloodstream during breathing.
pharynx: Helps the respiratory system by allowing air to make its way to the respiratory tract.
larynx: Produces vocal sounds and prevents the passage of food and other foreign particles into the lower respiratory tracts.
lungs: To help oxygen from the air we breathe enter the red cells in the blood.
ribs: To aid respiration and help protect the lungs.
diaphragm: Contracts and flattens when you inhale. Creates a vacuum effect that pulls air into the lungs, and relaxes when exhaling.
