answer:The physical structure of aquatic environments influences the distribution of organisms living within them. Organisms are adapted to specific water temperatures, salinity levels, water flow, depth, and substrate. These physical factors determine which species can survive and thrive in a particular aquatic environment. Therefore, the physical structure of an aquatic environment can limit or facilitate the distribution of organisms within it.

answer:The challenges in reconciling general relativity with quantum mechanics are related to the lack of a consistent mathematical framework to describe physics at the quantum level in the context of gravitational interactions. This gives rise to several paradoxes, such as the black hole information paradox and the measurement problem in quantum mechanics.

answer:Adverse possession is a legal principle that allows a person to gain ownership of a piece of property by occupying and using it continuously for a certain period of time, without the permission of the property owner. The period of time required for adverse possession varies by state, but typically ranges from 5 to 20 years. Adverse possession can only occur under certain conditions, such as the possession being open, notorious, exclusive, and hostile to the original owner's rights. Ultimately, the adverse possessor will gain legal title to the property and the former owner's rights will be terminated.
