Can you determine which instances reflect a valid experiment or conclusion? Check only those that are valid.
Orlov [11]

Answer:

Only options A (first one) reflects the instances with valid experiment or conclusion.

Quality of any experiment depends upon two things reliability and validity. Reliability is measure of regeneration of results every time an experiment is performed under specific conditions.

Validity is measure of accuracy of results of an experiment. It can be check by two ways: internal validity (checks the design of the experiment) and external validity (checks if the conclusion is the real explanation of the phenomenon).

Now, in marine biologist experiment, he concluded the results only after one breeding season. This makes his results unreliable as it might have happened by chance.

Similarly, in cola experiment the taste was only checked by one candidate i.e. Karl. He might have problem in his taste buds. In addition, the temperature of cola can also affects its taste which is not taken care of in the experiment. Hence, it is not the valid experiment.

Similarly. Jeanette could use more plants for her experiment and Robert just followed only one instruction. He didn't perform any experiment.

How can we use rocks to determine how an area used to look in the past?
Kamila [148]
Through looking at layers of rock you can tell what kind of things transpired. If you find Fish fossils you can assume that at one point in time, there may have been a body of water of some sort. if you find certain plants, you can deduce that there was a forest or a grassy pasture. Or if there are variations in the layer you may be able to tell what kind of soil was there at one point in time, or maybe if there is volcanic rock, you could rightly assume there was a volcanic eruption at some point.
