OK after reviewing the given answers I'm going to go with C. as the best choice because reading all of the others will tell you that they are longer than a epoch.
The answer should be B) protons and neutrons repel eachother. the protons and neutrons have opposite charges and repel eachother, so of course the nucleus needs to have a very strong force to hold it all together :P
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.
All the normal cells in the human body have the same number of chromosomes because all of their DNA is the same.
Answer:
intrinsic
Explanation:
Proteins are dynamic molecules that are capable of INTRINSIC motion that can have important functional relevance. The existence of this type of motion has suggested that enzymes are capable - even in the absence of substrate - of many of the same movements that can be detected during their catalytic cycle
