Answer:
Mass/mass percent concentration means the mass of the solute/mass of the solution times 100. You know both the mass of the solute (0.870 g protein) and the mass of the solution (10.279 g solution). So divide and multiply your result by 100.  (0.870 / 10.279 * 100)

Answer:
The correct answer is- make a prediction
Explanation:
A hypothesis can be defined as an explanation of any observation which can be confirmed by experiments and prediction is the guess about the future result of any observation.  
As here a biologist hypothesized that the sound produced by frog is mating calls than the next step of the biologist would be to make a prediction about response of that mating call by female frogs. This is called hypothesis prediction method. 
Therefore the right answer is- biologist will make a prediction.
