Explanation.

Scientific investigation is the process in which investigators and researchers use a methodical strategy to elucidate mysteries about the world around us.

A  scientific investigation typically starts with observations. Observations usually lead to mysteries.  A scientific investigation starts by formulating a hypothesis which is a probably the rational response to a scientific question, based on scientific knowledge. A prognostication is a statement which indicates all the possibilities under specific conditions.

The right answer is Explanation

Explanation:

The scientific method is a step by step procedure that is useful for researchers to follow in order to determine if there is any kind of relationship between the variables. Particularly, psychologist researchers try to find the cause of a behavior as much as the prediction and change of the human behavior in general. The researcher will form a hypothesis about what they expect to happen between to variables and with this goes to explain the question the investigator is asking about their study.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
