Explanation:
A scientific question can be described as a question which can be answered through the scientific method of research. Based on the scientific question, a hypothesis can be formulated. For example, for the option D, the hypothesis can be 'if the pollution increases, then the number of frogs decreases.' A hypothesis is a tentative statement which can be tested through experiments. Based on these experiments, results are formulated and conclusions are drawn. The question mentioned in option D can be answered through this method hence, it is the correct option.
Proxima Centauri is the nearest star to Earth.

Answer:
60.48L
Explanation:
By definition, at STP (Standard Temperature and Pressure), any gas takes up a volume of 22.4L.
Consequently, because the ideal gas law (PV=nRT) states that the number of moles is directly proportional to the volume of the gas, 2.7M of N2 takes up a volume of:
2.7*22.4L
=60.48L
So it can be used when having you know what with 2 other ppl a male and a female
