Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.
Answer:
Plants can't use N2 as is so the first option is wrong. They do have relationships with bacteria that live in nodules of the root and convert the nitrogen into ammonia, a usable form for the plants. So the second option is correct. There are bacteria living in the soil as well that convert nitrogen to ammonia so technically option 3 is also correct. Again, nitrogen if present in water would be in the form N2 which is not usable by plants so 4 is wrong.
These are correct:
use bacteria to convert nitrogen to usable form
In obtain usable nitrogen compounds from the soil
Answer:
Option (C).
Explanation:
Gap junction may be defined as the junctions that allow the communication between the neighboring cells. Gap junctions are leaky and allows the passage of the molecules easily.
Gap junctions constitute of connexons. Gap junctions can easily allow the flow of ions and small molecules from one cell to another cell. Gap junctions are known for the electrical coupling of cells as ions can easily pass through the gap junctions.
Thus, the correct answer is option (C).
