The salinity of a body of water suddenly starts increasing. A chemist believes that upstream contaminants are polluting the lake
Kryger [21]
The reason both of these are valid scientific hypotheses is because A) scientists with different educational backgrounds may put forth different hypotheses to explain the same data.
This approach in science is vital in making progress and has helped to explain many phenomena in the past. When scientists explain data using different approaches, they come to a more comprehensive conclusion.

Scientists studied reproduction in the New Zealand mud snail. They wanted to determine whether reproducing sexually or asexually
lubasha [3.4K]

A hypothesis is a claim that expresses a relationship between variables. D) Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

<h3>What is a hypothesis?</h3>

A hypothesis is a scientific conjecture, not verified, that requires corroboration. It is a possibility, but not a fact. It is a claim of how it works a relationship between two or more variables.

The researcher hypothesizes in order to predict what is going on or what is expected to occur.

A hypothesis must express what is expected to occur in a perfectly comprehensive manner. There must be a logical relationship between the involved variables. It must be objective. Usually, it is written in the present time.

There are different kinds of hypotheses: descriptive, correlative, differentiative, or causative.  

In the exposed example, researchers wanted to determine whether reproducing sexually or asexually was more beneficial for the snails.

Options,

A) <em>Sexual reproduction is advantageous over asexual reproduction because it reduces the rate of mutation accumulation. </em>

The benefit of reproducing sexually is that the risk of mutation is lower.

B) <em>Asexual reproduction is advantageous over sexual reproduction because it allows the snails to produce more offspring.</em>

<em />

The benefit of reproducing asexually is that a higher number of descendants are produced, which increases reproductive success.

C) Sexual reproduction is advantageous over asexual reproduction because it allows for snails to have increased genetic variation.

The benefit of reproducing sexually is that it increases genetic variation.

D) Asexual reproduction is advantageous over sexual reproduction because it decreases the snails’ need for social interaction.

The benefit of reproducing asexually is that there is no need for social interaction.

Social interaction does not really benefit snails as a species. This is not a variable that might influence in a significant way snails.

However, variables like the mutation rate, variability, and the number of descendants are useful to test how they benefit or not the snails.  

The hypotheses that would least likely aid the scientists to answer the question is <u>option D</u>.

Charles Darwin observed a unique beak size and shape in the finch population of each of the Galapagos Islands that he visited. W
Volgvan
In this question, there are no options given to choose from. So i would answer this question based on my knowledge. The most likely cause of the observed variation is adaptation and evolution. The birds of that island adapted to the food source and then they evolved as per the requirement of the place and food source.
