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).
An airplane wing is designed to make the air move <em>faster over the top than under the bottom. (c)</em> They do this by making the top of the wing curved and the bottom flat, so the air that flows over the top has farther to go.
It turns out, according to a scientist named Bernoulli, that air exerts lower pressure when it moves faster. So if it moves faster over the top of the wing, then there's less pressure on the top of the wing and more on the bottom, and the wing thinks there's a force that's LIFTING it . . . <em>very convenient and useful</em> if the wing is part of an airplane !

Explanation:
5.6kg = 5600 grams
multiply the mass value by 1000
Answer:
W = 30.38 N
Explanation:
Given that,
Mass of a rock, m = 3.1 kg
We need to find the weight of the rock on the surface of Earth. Weight of an object is given by :
W = mg
g is the acceleration due to gravity, g = 9.8 m/s²
W = 3.1 kg × 9.8 m/s²
= 30.38 N
So, the weight of the rock on the Earth is 30.38 N.
