Answer:
the 24-hour time period
Explanation:
A day can be determined in many ways, but the most correct and comprehensive way is to state that one day corresponds to the 24-hour period between sunrise and sunset. A day can also be defined as the period of time when sunlight is visible, that is, the period when one side of the earth is completely facing the sun.
Answer:
The correct answer is : one-to-one relationship
Explanation:
This case gives an example of a one-to-one relationship, which expresses one record in a set of information that is associated with one and only one record in another set. It happens when the information given can be linked with only one option in another table of information and vice versa. The element of one set is paired or matched with exactly one element of the other set.
Whenever a research is done, you must reject or accept a null hypothesis (the one you consider is not correct) or your work hypothesis (the theory you think is must probably accurate or close to the truth) usually, when performing a research, you will not always obtain positive or statistically significant results, that validate your hypothesis. Is actually, not unusual that extremes (or extraordinary results) come out (unexpected for several reasons: incorrect size of the sample, improper selection of the subjects- a bias- lack of correct determination of the variable measured or failure to determine the type of the variable-numerical, categorical, ratio,etc-)
Positive or negative results are yet, results whether they prove or reject your hypothesis. Failing to establish a scientific hypothesis does not necessarily mean that they did something wrong, it just says that the hypothesis tested does not approach correctly to the epistemological truth (ultimately, any research is only a mere approximation to reality). Therefore, when two scientists deny sharing<em> unusual results</em>, they are acting unethically, hiding results that can mean something from a different point of view.
