Answer:
The pulmonary vein and the jugular vein.
Explanation:
The greatest difference between the pulmonary vein and the jugular vein is that pulmonary vein takes oxygenated blood from both lungs towards the left atrium of heart while jugular vein takes the deoxygenated blood from head back towards right atrium of heart through superior vena cava.
So, the main difference is oxygenated and deoxygenated blood in the above mentioned veins.
Answer: Precise measurements are important for Scientific Accuracy in order to get correct results
Explanation:
Precision is how close the Agreement is between repeated measurements under the same conditions. For example, if a measured value 36.7cm has three digits, or significant figures. Significant figures indicate the precision of a measuring tool that was used to measure a value
Accuracy is how close a measurement is to the correct value for that measurement.
When taking scientific measurements it is very important to be both precise and accurate. Bad equipment, human error can give inaccurate results.
