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).

soldier1979 [14.2K]

Answer:

The distance that the honey flowed would be the dependent or outcome variable and the temperature of the honey would be the independent variable.

The dependent variable is what is being measured in an experiment. You can remember it by thinking “it depends on what you’re changing.”

The independent variable in an experiment is what is being changed. You can remember this by thinking “the Independent variable is what I as the scientist change.”

Answer:

when the ground is very hot and the air is cool.

Explanation:

The hot earth warms a layer of air right above the ground. Light is refracted as it passes through the cool air and onto the hot air sheet (bent). A coating of very warm air near the earth bends the light from the sky almost into a U-shaped bend.
