The answer I believe would be talking to plants may or may not helps plants grow faster because the amount of water given was likely different for each group. I say this because there are more than one manipulated variables. (Each experiment should only have one manipulated variable to really be able to come to a conclusion) The student wants to see if talking to the plant will help. But the student also used different watering methods. So there was more than one manipulated variable. This can not give a good enough result because we do not know which affected the plant- the talking or the watering method/amount.
Hope this helps!

When a small populations' gene frequencies are changed drastically by chance alone it is called a genetic drift
The primarily use of coal is mostly used for electricity generation, steel production, cement manufacturing, and as liquid fuel.
Advantages: it helps produce electricity, coal energy is affordable energy source because coal's stable price compared to other fuels sources, coal is easy to burn, coal produces high energy upon combustion, coal energy is inexpensive, coal is abundant, coal energy is a reliable energy source.
Disadvantages: coal energy produces large amount of carbon dioxide which leads to global warming and climate change, the burning of coal is not environmental friendly because it produces harmful byproducts and gas emission such as sulfur dioxide, carbon dioxide and nitrogen oxide that causes pollution to the environment including acid rain, coal energy is nonrenewable energy source, coal is fast depleting because we dont consume too much of it, coal mining ruins the environment and puts the lives or people especially the coal miners in danger. <span />

Answer: Allopatric Speciation
Explanation:
Allopatric speciation occurs when new distinct species are formed due to the separation of a specie into two separate groups. These two groups are kept away from each other.
In allopatric speciation there is no exchange of genes between the two separate groups.
Allopatric speciation can also be known as geographical speciation.
