WILL GIVE BRAINLIEST1 An intestinal epithelial cell powers the movement of glucose into the cell against its concentration gradient by simultaneously transporting sodium down its concentration gradient. Which transport mechanism is responsible?

primary active transport

Secondary active transport

osmosis

facilitated diffusion

Secondary active transport by a symporter

Secondary active transport includes uphill transport of one substance against its concentration gradient coupled with downhill transport of another substrate. Glucose is transported against the concentration gradient into the cytoplasm and this active transport is driven by downhill transport of Na+ into the cells. This makes the transport of glucose a secondary active transport. Both glucose and Na+ are transported into the cell (in the same direction). Since both are moved simultaneously in the same direction, it is a symport.

Explanation:

1100

Explanation:

There is 10% of total energy in each increasing trophic level.                    10,000 / 10 = 1,000 ,so there are 1,000 units of energy in trophic level 2.

1,000 / 10 = 100, so there are 100 units of energy in trophic level 3.

1,000 + 100 units of combined energy would be 1,100 units of energy.

Hope this helps!
