Answer:
Heat fluctuations
Explanation:
Water's high heat capacity means that it requires a lot of energy to raise the temperature of a unit volume of water by one degree. It also requires to lose this same amount of energy to lower its temperatures by one degree.
This means that as land temperatures fluctuate a lot from day to night depending on the rate of sunlight hitting the earth, the waters of the oceans remain more or less within very a small range of temperatures. This protects the organism of the oceans from high heat fluctuations that may cause heat shock.
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).
Nitrogen is Abiotic because it is non-living.
As humans we farm (agriculture) and plowing/deforestation/water use can erode the rock which may contribute to the rocks cycle
