A reference point is a point in geometry or general which is used to determine or refer to another point. In reference to this point, measurements can be done. Like, a reference point in space is used to measure distance or displacement to another point. A reference point in time is used to measure the time interval of an event. A reference in space-time can be used to measure the speed or detect object's motion. Hence, the following points apply:
→A position from which to measure future distance
→a set of standard units for measuring displacement
→a method for determining the speed of an object
→a way to detect an object’s motion
A reference point provides a way/method to infer information about the object.
Answer:
yes
Explanation:
The plants use water (H2O) from the soil and carbon dioxide (CO2) from the air and recombine them to form carbohydrates (CH2O) and oxygen (O2).
