The five steps that are always taken in scientific research are;
- establishing a hypothesis
- doing research and assembling data
- and finally proceeding to a conclusion
<h2><em><u>
Explanation:</u></em></h2>
- Arya already performs the first two steps; as she first recognize the problem i.e. she observes the dry glass and she also formulate a hypothesis that "the water content in the soil is about two-thirds lower than that of other yards in the area"
- Now she will collect the data and conduct the experiment on the soil and glass and then she will assemble the conclusion based on the results.Now she will collect the data and conduct the experiment on the soil and glass and then she will assemble the conclusion based on the results.
Photosynthetic cyanobacteria reengineered the planet. Photosynthesis led to two more singularities - plants and animals appeared. Atmospheric oxygen resulted from a change to a microbe's metabolism that evolved once, at a specific time in the earth's history
I believe it is B. Cars used to be in factories and assembly lines, which work too long sometimes. As companies expanded and the technological age advanced, more and more cars were being made. Along with some cars that became experiments first, then a reality.
Uses natural pressure
Has groundwater stuck between impermeable layers
are the statements which describe the attributes of an Artesian well.
<u>Explanation</u>:
- Artesian well, well from which water is pumped under natural pressure without pumping. It is dug or dug wherever a soft dip, porous rock layer obtains water along its ridge at a point higher than the rate of the ground surface at the well site
- .First, artesian groundwater is the same as any other groundwater type; the only distinction is how it reaches the surface.
- An artesian well is simply a well that doesn't involve a pump to get water to the surface it happens when there is sufficient pressure in the aquifer. This gives rise to positive pressure.
