Most sedimentary rocks are formed in a process that involves water. It is one of the primary factors in the mineral formation of chemical sedimentary rock. Thus, option D is correct.
Mineral crusts are formed on the sedimentary grains as a result of dissolved minerals in groundwater precipitating (crystallizing) from water in the pore spaces and eventually cementing the sediments to create a rock.
Chemical sedimentary rocks are created when minerals precipitate from water. When dissolved substances leave water, it precipitates. Take a glass of water and add some salt (halite), for instance.
Additionally, it acts as an erosive and weathering agent, generating the grains that eventually form detrital sedimentary rock.
Therefore, materials dissolved in solutions is one source of the sediments that form sedimentary rocks.

B. In both cases, Islam spread among societies that traded with one another. This contributed to Islam becoming the dominant religion in Africa and Asia.
C. In both cases, socieites were brough into contact through trade. The cultural exchanges that went along with that trade enriched those societies.
D. In both cases, interactions between societies led to conflict despite the success of trade contacts. These clashes left trading societies vulnerable.
b. An unstable ecological niche leads to various selection pressures, which in turn causes the species to remain in a stage of stasis.
c. A stable ecological niche leads to various selection pressures, which in turn causes species to remain unmodified or in stasis.
Answer:
A.
A stable ecological niche leads to absence of selection pressure, which in turn causes species to remain unmodified or in stasis.

Technology is also being harnessed to help prevent food waste, working to keep food out of landfills by keeping better track of it at all levels, from the farm to the table. With up to a third of the world's food resources thrown out, data collection technology has the potential to greatly reduce that figure.
