The independent variable is the one that can be changed
I think the correct answer would be water temperature because on the table, the water temperature is increasing by 10 each time so it is changing.
hope I'm right and hope I helped :)
Your answer would be B. Hope this helped :)<span />
Answer:
As the type of investigation is not discussed, lets answer the question generally.
Explanation:
One of the properties of water is that water in the form of ice is less dense as compared to water liquid water. This property of water lets fishes survive in conditions when the temperature is freezing.
The hydrogen bonds in water make the water turn into a vast, honeycomb structure when the temperature is below 4 degrees Celsius. This causes the ice to float on water and the fishes can stay alive in the liquid water underneath the ice.

can also glimpse the awful effects of Alzheimer's disease when they look at
brain tissue beneath the microscope:
Alzheimer's tissue has numerous fewer nerve
cells and synapses than a well brain.

<span>
<span><span>Dead and dying nerve cells contain tangles,</span> which
are produce of twisted strands of a further protein.</span>

<span>Scientists
are not absolutely sure what causes cell death and tissue deficiency in the
Alzheimer's brain, but plaques and tangles are key suspects.</span>
