Answer:
what causes the second voltage-gated Na⁺ channel to open is that after the first channel opens, the movement of many types of ions (both inside and outside the cell) alters the distribution of charges near the second channel, causing it to open. Option D
Explanation:
Voltage-gated sodium channels are known as transmembrane proteins that cause rapid depolarization resulting to upstroke of action potentials in neurons and are thus important to nerve impulse conduction.
Our nervous system contains cells, the neurons that send information to and from the brain and spinal cord .
Sensory nerves receive stimuli from receptors by a change in voltage or membrane potential that occurs across the plasma membrane.This voltage difference is determined by the relative concentration of potassium and sodium ions inside compared with outside of the nerve cell. Hope this helps. Thanks
Answer:
adds; convection
Explanation:
because in order for ice to melt, you need to add heat energy. convection is when you make something hot rise and something cold melt.
Solid wood is a term most commonly used to distinguish between ordinary lumber and engineered wood, but it also refers to structures that do not have hollow spaces. Engineered wood products are manufactured by binding together wood strands, fibers, or veneers with adhesives to form a composite material.

Answer:
Please find the answer to the question below
Explanation:
In chemistry, the following mathematical formula is used to calculate the number of moles contained by a substance:
mole = mass of substance (g)/molar mass of substance (g/mol)
Molar mass of salicylic acid (C7H6O3) = 12(7) + 1(6) + 16(3)
= 84 + 6 + 48
= 138g/mol
Mass = 5.50grams
mole = 5.5/138
mole = 0.039
Approximately, the number of moles of 5.5grams of salicylic acid is 0.04moles. This is in accordance with the mole value (0.04) given in this question.
