How do you grow seedless fruit, like grapes and satsumas an shit?
Ask the BSG as they are smart Page 14
You induce parthenocarpy. Usually, fruit needs seeds because seeds produce a plant growth regulator, or hormone, auxins. If you take out the seeds, but spray on auxins, the fruit will still ripen. I think to get the seeds out of grapes or satsumas you have to select mutant offspring which are seedless but which usually wouldn't ripen, and then spray them with auxins to make them ripen.
Apparently, it's usually done not by a seedless mutant offspring but by a mutant offspring which has seeds, but which cannot make the seed coats harden. The seeds therefore naturally disintegrate from acids in the fruit, I guess, and cuttings are taken from these mutants to grow new, other seedless grape plants.
Amaaaaaaazing. 
Biology lessons are good for something.
How come you didn't do biology at uni Scats?
Because I find it incredibly interesting, but too theoretical. Also, I didn't do chemistry A-level, which comes to be somewhat essential at degree level, and not studying it even put me at a disadvantage during A-level biology to some extent.
I was torn between English and history, but decided that English was most likely to include things like history and languages.
Good thinking Scats.
I do Humanites. That includes English and History plus 6 other subjects plus it's combined with media studies. Yes my second degree will be a combined one!

Scats am smart, we keep her, she make crops grow.

Didn't you know that? 
All girls know this sort of thing.

We learn it the same day we learn how to iron and do the twisty hair thing with towels.

And yet the phrase 'we cannot be late' seems to escape you entirely.

Yeah but you would say that wouldn't you though!
(Actually very impressed!)

That is witch-craft, that is.
