Answer:
D- The effect of drift on average fitness is not predictable
Explanation:
Genetic drift is a mechanism causing change in allele frequencies in a population from one generation to another. Genetic drift happens by random sampling and the benefit or harm of the allele is not a factor in deciding which allele stays and which is deviated from.
A beneficial allele may be lost, and a harmful allele fixed into the next generation. Genetic drift affects both small and large populations but its effect is more pronounced in small populations.
Since Genetic drift happens by chance and any allele can be selected, the effect of the drift on the fitness of the population cannot be predicted. If a harmful allele is selected, there will be a negative effect on the fitness. On the other hand, if a beneficial allele is selected, there will be a positive effect on the fitness of the population

If a scientist sets up an experiment and the results do not support his hypothesis he should conclude that "he may want to alter some aspects of experiment and try it again".
<u>Answer:</u> Option B
<u>Explanation:</u>
Research and experimenting is all about search and re-search for achieving acceptable result in order to meet the demand of project accordingly. It demand huge patience and hard work but also smart work for saving time as much as possible.
If a scientist results do not support hypothesis than after a short break he should alter some steps or parameters of experiment and try it again. Because it may occurred due to an error. And errors are needed to be understood and then rectify it by repeating the procedures with more sincerity.
Answer: Water waves are surface waters. Waved are created by energy that is passing through water particles. As the wave crest move, it causes water particles to move in a circular motion. Water don't travel in waves, waves energy trigger water movement which is driven by wind, this create friction between the wind and the water. The waves passes through the water but water particles remain in their formal position.
Explanation:
Water waves are surface waves in that they travel in circular direction due to energy created by the wave.
