The correct answer is: Sodium and potassium ions move by active transport, and glucose moves by facilitated diffusion.
Because sodium and potassium are moved through cell membrane against their concentration gradients, transport requires energy (ATP), so it is active. <span>Glucose is a polar molecule and because the plasma membrane is impermeable to polar molecules transport of this important nutrient is accomplished by carrier proteins. This process is called facilitated diffusion and it is passive transport (doesn’t require energy).</span>
They are called sea plankton. They are microscopic. One way you can see them is through a microscope. Good luck !
Your answer would be B. (2) seeing that testosterone is in men and insulin would be incorrect because the answer choice doesnt include estrogen--the key hormone produced in women.
