Thank you for the amazing video! The informations were very clear and easy to understand. I am taking the exam next month, I am homeschooled, so I don’t have the opportunity to do the experiment hands on so I am very thankful for the helpful information 😊

Hi, in Maths Made easy, the answer to the use of HCL is to stop mitosis from occurring, but here it says to soften the tissue, which one would i write in the exam?

Both are options in the markscheme. Either answer will get you a mark.

If you can see two nuclei in the cell (indicating telophase (?)), do you include these in the mitotic index please?

For calculating the mitotic index, should my answer always be 2dp (2 decimal places) or will I get how many decimal places or significant figures are needed in the question?
@MissEstruchBiology

If its not specified in the question then 2dp is a good standard

For this practical when we're calculating mitotic index, in the video you mention it's a percentage. However, when we did a mock I didn't get a mark when I times by x100. For mitotic index do we x100?

Sometimes they require it as a percentage, but sometimes remain as a decimal. The units given should indicate this
