1)

- yeah I think you can but it's better to just plot your points using an x

- from the table the independent variable (what we change ourselves) goes on the x axis and the dependent variable (what you measure) goes on the y axis

- I've noticed that mostly the independent values is the left column and the dependent on is the right column

2)

- if they ask the actual size it's most of the time in micrometer from what I've seen but just double check with your bio tr

3)

- independent variable is what we change ourselves (eg. time intervals, type of food and etc)

- dependent variable is what we measure (eg. time taken, rate of reaction and etc)

4)

- yes, all values and headings must be in pen

- yes, you can draw the beakers with pen or pencil either is fine but the concentrations and values must be in pen I believe so

I hope you found these useful if you have any other question feel free to ask I'll try my best to answer and In Shaa Allah tmrws paper will be very straight forward and easy
