Answer:
The hypothesis can be made as follows:
' If there are less or no estuaries in a river, then there will be more erosion at the shorelines.'
A hypothesis is a tentative statement which can either be supported through experiments or proven to be wrong.
In the following scenario, we can conduct experiments by taking into observation those rivers which have estuaries and those which do not have estuaries. We can then compare the erosion of the shorelines of the rivers to validate our hypothesis.
The probability that their son exhibits the 'color blind' trait is 0%. It is a type of inheritance linked to the X chromosome.
<h3>Inheritance linked to the X chromosome</h3>
In men, the patterns of inheritance linked to the X chromosome don't follow conventional mendelian inheritance because men have only one X chromosome.
Conversely, women have two X chromosomes, thereby the inheritance pattern resembles Mendelian inheritance.
It is important to highlight that color blindness is a recessive trait on the X chromosome.
In this case, the mother is a carrier, thereby the probability of passing this trait as a carrier to her son is 50%, whereas the father is normal, thereby the probability of passing this trait to his son is 0%.

D is probably right cos you are comparing data
The direct source of energy to move the sailboat is probably wind, since wind is what pushes the sail of the sailboat, which is what propels the sailboat forward.
Hope this helps!
