Two students are working together on an experiment that measures the effect of different liquid fertilizers on the thickness of

plants’ stems. Which is most likely to result in the greatest amount of error in their scientific experiment?
One student measures the plant stem widths by using calipers. The other student measures the widths of the same plant stems again by using a different pair of calipers.
One student measures the plant stem widths by using calipers. The other student types the measurements as they are taken into a computer spreadsheet.
One student measures liquids for the experiment by holding the flask up at eye level. The other student measures liquids for the experiment while the flask sits on the table.
One student weighs liquids for the experiment by using a calibrated scale. The other student weighs liquids for the experiment by using a different calibrated scale.

The correct answer is option (C) One student measures liquids for the experiment by holding the flask up at eye level. The other student measures liquids for the experiment while the flask sits on the table. Measuring liquids by holding the flask at eye level is the greatest amount of error in the experiment.

When liquid is being measured in a flask, the liquid shows a curve downwards which is called the meniscus. For measuring the transparent liquids, the lower meniscus touching the graduation of the should be considered and for measuring the colored liquids, the upper meniscus touching the graduation of the flask should be considered. When, the measurement is done by holding the flask at eye level there is always an error as it should be kept on a flat surface and measured by eyes directly leveling with the liquid. This gives a correct measurement which was done by the other student. Thus, one student measuring the liquid by holding the flask at eye level will have a wrong measurement and the other student measuring the liquid while the flask sits on the table gives the correct measurement and the results of the experiment will vary.

Brrunno [24]

Answer:

Evolution.

Explanation:

A small portion of the moth population began going to a different type of tree within the same forest to breed instead of the older one because of the evolution. Due to this evolution, the moth is able to breed on another tree. The characteristics of some moth specie changed over several generations due to may be change in their genetic makeup so we can say that it is because of evolution.
