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.
Answer:
Option A
Explanation:
The flower cells are hypertonic to fresh water but hypotonic to the salt solution.
Flower cell is hypertonic to fresh water, this means that the amount of solute in the solution outside the flower cell is higher than the solute content inside the flower cell.
While when a flower cell is hypotonic, it means that the amount of solute in the solution outside the flower cell is lower than the solute content inside the flower cell.
This is the reason why a flower plant placed in vase of water stood and become erect, while the same flower placed in a salt solution wilted.
Hence, option A is correct
plant like protists are autotrophs. this means they produce their own food through photosynthesis.
