A warm, moist air mass collides with a cold, dry air mass
There are different kinds of tides. This change occur because when the gravitational pull of the sun works along with the gravitational pull of the moon on Earth, it leads to the oceans bulging out.
- This result above makes the high tides as been little higher and low tides been little lower than normal.
Spring tides are known to be the deepest as oceans levels are highest in this kind of tide. The neap tides are known to be the shallowest.
This often occurs when the moon, earth, and sun are said to be at a right-angled plane. Therefore, the gravitation pull of the moon and sun on the oceans do counteract each other making its net effect is smaller.

Answer:
Ligand gated.
Explanation:
Channels are important as they help in the transferring of one molecule from one place to another inside the cells. These channels also provide the way of cell communication.
The ligand gated channels generally open in response to the binding of ligand or some molecules with the channel. Sodium gated channels open in response to the binding of sodium with the channels.
Thus, the correct answer is option (a).
