Imagine you created a toxin such that when a neuron fired an action potential, the toxin would bind immediately to the sodium-po
loris [4]

Answer:Maintaining resting potential and returning to resting potential after the hyperpolarization phase of an action potential

Explanation:TOXINS are chemical substances which are known to be POISONOUS produced with living organisms that causes harm to other organisms, examples include Venom from snakes which when a person is bitten by a Snake it will possibly lead to death if not adequate treated.

HYPERPOLARIZATION is a term that explains the change in membrane potential due to toxin,it make the membrane more electronegative. When the toxin has hyped the level of Sodium-Potassium level returning to a rest state will be most affected.

Explain why a strong attraction occurs between particles as a result of the transfer of an electron from the less electronegativ
iren2701 [21]

Explanation:

When a less electronegative atom comes in contact with more electronegative atom then more electronegative atom tends to attract the electrons from less electronegative atom.

Hence, a partial positive charge is developed on less electronegative atom and it has given an electron. On the other hand, a partial negative charge tends to develop on more electronegative atom due to gain of an electron.

Therefore, due to the presence of these opposite charges a strong force of attraction is exerted on both the atoms. As opposite charges attract each each other and like charges repel each other.

A gas is heated from 263.0 K to 298.0 K and the volume is increased from 24.0 liters to 35.0 liters by moving a large piston wit
Triss [41]

Answer:

The final pressure is approximately 0.78 atm

Explanation:

The original temperature of the gas, T₁ = 263.0 K

The final temperature of the gas, T₂ = 298.0 K

The original volume of the gas, V₁ = 24.0 liters

The final volume of the gas, V₂ = 35.0 liters

The original pressure of the gas, P₁ = 1.00 atm

Let P₂ represent the final pressure, we get;

\dfrac{P_1 \cdot V_1}{T_1} = \dfrac{P_2 \cdot V_2}{T_2}

P_2 = \dfrac{P_1 \cdot V_1 \cdot T_2}{T_1 \cdot V_2}

P_2 = \dfrac{1 \times 24.0 \times 298}{263.0 \times  35.0} = 0.776969038566

∴ The final pressure P₂ ≈ 0.78 atm.
