Has mitochondria so there is lots of energy to get to the egg. Has a tail to swim through. Is a haploid so it can join with the egg to create a normal cell chromosomal amount.

How is a egg cell specialised to its function?
Has nutrients and is a haploid so when it combines with the sperm it can create a human about of chromosomes.

How is a ciliated epithelial cell specialised?
Has tiny hair-like structures so it can clean and push the substances in the direction along the surface of the tissue.

What happened to the potato chip in pure water?
The mass increased as the water moved into the chip.
12 of 14
Why do we measure percentage change of mass in the potato chip experiment?
So that it is more valid to qualify and compare. They mightn't have all began at the same mass. Ensure it is fair while comparison.
13 of 14
How do we work out the percentage change in the chip?
(end mass - beginning mass) ➗beginning mass. X 100
