<h2>Answer:</h2>
Correct option is B.
B) A car's velocity decreased from 10m/s to 5m/s.
<h2>Explanation:</h2>
Velocity is the vector quantity i.e. It needed both direction and magnitude to define it. Velocity is actually the rate of change of subject with respect to some frame reference.
Acceleration is the rate of change of velocity with respect to its velocity. The standard unit of velocity of meter per second square.
Answer:
The statement that accurately describes how scientists collect data is the method used to collect data depends on the desired data.
Explanation:
When a scientist decides to conduct research, he or she must consider the purpose of the research and the best way to conduct it. Once the purpose of the research has been defined and the hypothesis has been put forward, data collection becomes one of the most important steps.
Data collection must be adapted to the needs of the phenomenon to be studied, taking into account the most appropriate and reliable methods to achieve the objective.
<em>An adequate data collection method means choosing the best option to collect the necessary information and obtain the expected results in the investigation.</em>

The lactase-persistence mutations are roughly as old as the oldest milk-holding vessels or pots
lactase persistence:
Lactase persistence is an example of natural selection, which can cause some humans to continue the activity of the lactase enzyme in adulthood also.
The hereditary examinations and studies propose that the established mutation related to lactase persistence began a long time back, in populaces that started domesticating and dairy cultivation during the Neolithic age when pastoralist populaces started to utilize milk for their livelihood. As found and studied that “the lactase-persistence mutations are roughly as old as the oldest milk-holding vessels.” The cultural and social activities of dairying and drinking non-human milk gave an environment wherein lactase persistence was favorable. DNA proof demonstrates that mutation in the lactase gene emerged in these populaces around a similar time.
