how should we know the plotting of graphs in X-axis and Y-axis ???

Always the first column is X axishow should we know the plotting of graphs in X-axis and Y-axis ???

Buffer solution is added to maintain the pH of any solution in experiments.What is a buffer in biology?

^^example of a tally chart. In the question, they have given the ranges. e.g, if there are six worms in the first range, you draw 4 line and cut them (the cut represents the 5th line) and you put one more line for the sixth worm. Its like the lines for mark7 in the above example.
Hope you understood
The method is the same i.e., the lines one. The +1 or +2 are those which you are measuring so your measured length might be different from mine by a few mm. Because of this they can fall in different ranges. So, if from the measured worms, only 2 fall in the 11.0-12.9 group, two more lines will be there along with those whose measurements are already given. Hope you are clear now.I got it actually i knew it but what does the marking scheme say :/ It is like +1 +2 +3.... Sorry about disturbing yo but i have my exam tomorrw
Use of water bath,Test tube holder,Safety spectacles,use of lab coat,tie the hai back i hope this helpsPlease give examples of safety measures in testing for food tests ??
Thank you so much I hope yo pass in flying colorsThe method is the same i.e., the lines one.

Btw, i too have my exam tomorrow. Plz pray for me and gud luck for your exam.
Could you please post the LinkIf someone could help me with question 4 of physics p6, s08. That would be really appreciated
Thank you.
