Answer:
Neither A nor B is correct
Explanation:
Hydrologic cycle is the sequence of different conditions through which the water passes from oceans to clouds, precipitates as rains, comes to the rivers and finally reaches the ocean.
This first statement in the question said that water will end up in the river which is not true because water from the river ultimately ends in the oceans because all the rivers terminate in the oceans finally.
The second statement is also wrong because when water from one ocean vaporizes and becomes cloud, it can travel large distances as clouds in the effect of wind and thus may get precipitated in the form of rain in some other part of the world. So, it is not necessary that the water will end up in the same ocean.
It takes seven seconds for the pupil to adapt once again to dark conditions after getting exposed to headlight glare.
The pupil of the eye refers to the black circle at the midpoint of the iris. The pupil functions mainly to monitor the amount of light getting inside the eyes, to make sure that to much light does not blanch out the visions in extremely bright light conditions, and to capture as much light as possible in dim light conditions.
Biotic factors are anything in a ecosystem that is living, was living, or is going to live.
From this we can conclude that the biotic factors are remains of dead organisms and flora and fauna.
Temperature and minerals in the soil are abiotic, meaning they will never live.
