Which choice best characterizes K+ leakage channels? View Available Hint(s)
hoa [83]

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
amm1812

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 !

A rock has a mass of 3.1 kg. What is its weight on earth
Masteriza [31]

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.
