Hi there,
How is the earthworm adapted to its feeding habits?
Well a earthworms are tube shaped, some worms such as segmented worms can be found in soil.They are there to stay moist and to feed on organic matter.
So an earthworm's<span> digestive tract is laid out straight from the oral orifice to the anus. The parts of the digestive tract regulate or absorb the nutrients from every meal.
</span>Hope this helps!
I used to have a worm farm myself, it was really cool to see really up close on how worms live and how they feed on organic matter in the soil.
- The balance between the chemical and electrical forces pushing potassium through potassium channels and across the membrane is represented by the potassium equilibrium potential.
- At the equilibrium potential of potassium, which is -80mV, there is no net movement of potassium ions.
<h3>At potassium's equilibrium potential, what happens?</h3>
- At equilibrium, the electrical potential gradient across the membrane precisely balances the gradient of K+ concentration.
- There is no net migration of K+ from one side to the other, despite the fact that K+ ions continue to traverse the membrane via channels.
<h3>How does potassium diffuse in order to influence the membrane potential?</h3>
- Potassium ions will flow down their concentration gradient, or towards the exterior of the cell, because the membrane is permeable to them.
- Although the membrane is not permeable to sodium, there is a concentration gradient that favors sodium diffusion in the opposite direction.

Answer:
D
Explanation:
Intestinal cell takes in glucose against Concentration gradient (uses energy in the form of ATP) to transport glucose into cell.
In blood cell, uptake of glucose occurs down concentration gradient. Hence, its facilitated diffusion (passive transport)
Glucose is a polar molecules due to presence of polar hydrophilic - OH group, hence carrier proteins are needed to provide a hydrophilic channel for glucose to enter the cell via facilitated diffusion.
