Answer:
The organism belongs to the Protista kingdom as it is unicellular, has cell walls, and has the ability to produce spores.
When Amanda poured some of the liquid in a test tube, she noticed that the edges if the water curved upward, which is an illustration of adhesion.
When Pol filled another test tube to the top, the liquid formed a low dome, which is a proof of cohesion.
When Amanda added table salt to the first test tube and shook it, she noticed that the liquid had dissolved the solute.
All of these observations are suggesting the existence of covalent bonds.
Pol determined that the pH of the sample is 7 that indicates that the sample is neutral.
Based on all the proof gathered by Pol and Amanda, the unknown liquid is water.
]To calculate the amount of heat entering or leaving a system, the equation

=
m
c
Δ
T
is used.
Explanation:
m = mass (in grams)
c = specific heat capacity (J/g°C)
ΔT = change in temperature (°C)
Here, we will use the specific heat capacity for liquid water which is 4.19 J/g°C.
The mass given is 25.0 grams.
As for the change in temperature, I will assume that it start off at room temperature, 25°C.
