The independent variable is the amount of water consumed by the football players.
The dependent variable is the football players' endurance, measured by how many times they can run up and down the bleachers before catching their breaths.
The coach's hypothesis was that the more water consumed, the more endurance the players will have.
There is not a control group present in this experiment, but it would be the set of players who did not drink a bottle of water before practice.
The experimental group is the set of players who did drink a bottle of water before practice.
The constants in the experiment are the operational definitions of endurance (how he measures their endurance), the amount of water each player drinks throughout the week, and the players used in the experiment.
The lack of a set control group poses a threat to the accuracy of the experiment's results.

Answer:
Approximately it will consume 55% of the total time in the interphase i.e. 800 minutes.
Explanation:
The time required in different phases are as follows:
It takes 800 minutes for interphase
It takes 400 minutes for prophase
It takes 120 minutes for metaphase
It takes 80 minutes for anaphase
It takes 40 minutes for telophase
Total -- 24 hours
From this it can be concluded that around 55% of the time spent in the interphase, whereas only 28% in the prophase, 8% time for metaphase, 6% Anaphase and 3% Telophase. This is all happens in the onion cell but in case of the human cell, prophase it takes about 15 min, in prometaphase it takes 15 mins, metaphase takes in about 20 min, Anaphase takes minimum of 3 min and telophase is about and cytokineses are about less then 10 mins.
A scientist must always try to avoid bias in scientific
experiments. It is important for scientist to avoid leaning into their bias
when trying to confirm their hypothesis. As much as possible the scientist
should be able to follow the scientific method to avoid bias.
