Answer:
The correct choice is ''ion electrochemical gradients''.
Diffusion of ions across membranes through specific ion channels is driven by <u>ion electrochemical gradients</u>.
Explanation:
An electrochemical gradient can be considered as that electrical (electrostatic pressure) and chemical (diffusion) force that determine the movement of molecules and ions across the membrane. This electrochemical gradient, in addition to causing movement of substances through cell membranes, is also a type of potential energy available for the performance of different cellular activities, potential energy called membrane potential.

Answer:
<em>Goose Flesh</em><em> also known as </em><em>Goose Bumps</em><em> also known as</em><em> Cutis Anserina (scientific term).</em><em> It is a temporary change of skin. The skin becomes rougher due to fear, cold, excitement, etc. Small bumps appear on the surface of the skin because the arrector pili muscles contract. </em>
Hope this helped

I think the correct answer from the choices listed above is option C/ One reason that a product does not always form is due to unfavorable geometry of the reactants involved. When the geometry is not good for substances to react then no reaction can occur although there is enough energy present.
<h2>Answer 1:</h2>
The gravitational force is a force that attracts any objects with mass. Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy including planets, stars, galaxies, and even light are brought toward one another.
Answer 2:
Gravity keeps things together. It is a force that attracts matter towards it. Anything with mass creates gravity, but the amount of gravity is proportional to the amount of mass.
Gravitational force is critical to our universe because with out gravitational force we cannot walk on earth, all the matter on earth cannot stay on it with out gravity. Everything will start floating in air with out gravity.
<h2>Answer 3:</h2>
Gravity is the powerful force that glues our universe together.
- One of the most noticeable effects of gravity in the solar system is the orbit of the planets.
- The planet keeps moving but is always caught up in the push-pull forces caused by the interaction of these gravitational forces. As a result, the planet begins orbiting the sun.
- The same phenomenon causes the moon to orbit around the Earth except its the Earth's gravitational force not the sun's that keeps it moving around us.
