Antithrombin is a protein molecule that inactivates several enzymes of coagulation system. It is a glycoprotein produced by the liver consisting of 432 amino acids and three disulfide bonds. The antithrombin found in the blood and the cell lining blood vessels function to prevent unwanted formation of clot.
The advantage for the reduced gametophytes in seed plant is that they gain nutrients from the sporophytes
Gametophytes are microscopic and have capacity to develop from spores retained in the sporangia of parental sporophyte. This kind of arrangement protect developing gametophyte from environment stress which enable it to gain nutrient from sporophyte.

The validity of the hypothesis cannot be confirmed or refuted from only one experiment. By using a series of experiments, the human error or measurement error is reduced to a minimum. Furthermore, more than one factor can be used to determine the validity of the hypothesis.
I will respond to this student that the experiment needs to be repeated multiple times before a conclusion can be drawn! Also, the data will refute or confirm the validity of the hypothesis and not the researcher's own opinion/rational.
