Since the electrons and protons have the same magnitude (but different sign) of charge, the number of protons and electrons must be the same for the atom to be electrically neutral.
Answer:
C. <u>Trans-membrane protein channels that are always open to allow K+ to cross the membrane without the additional input of energy</u>
Explanation:
As we know that K+ leakage channels indicate the Potassium leakage channel. The best characterizes about K+ leakage channels is that there is a Trans-membrane protein channel which is always open to allow K+ to cross the membrane without the additional input of energy.
Actually when a cell dies its membrane potential gets more positive and finally reaches zero .
The key point is that the cells spend energy to maintain the intra-cellular ionic concentrations constant.
The membrane permeability of K+ is much higher than the membrane permeability of Na+.
Therefore, the correct choice is option (C).
B. Learn and follow the local rules about open fires, camp stoves, kerosene lanterns, and other sources of fire.
Answer:
(a) The equivalent resistance is 18.06 Ω
(b) The current in each resistor is 0.665 A
Explanation:
Given;
first resistor, R₁ = 2.25 Ω
second resistor, R₂ = 5.90 Ω
third resistor, R₃ = 9.91 Ω
Equivalent resistance;
2.25 Ω + 5.90 Ω + 9.91 Ω
18.06 Ω
The current in each resistor;
For series connection, current is the same in every resistor.
V = I(R₁ + R₂ + R₃)
