Physics, Chemistry and Biology: Post your doubts here!

[Mr.Physics]

Hi guys! Are epithelial cells and goblet cells the same? If not, can u help define each of them? Because my book says the villus is covered w goblet cells but the mark scheme to qp32 M/j 2014 BIOLOGY says they are epithelial cells (it is in question 5b).

Many thanks!

Goblet cells are those cells that produce mucus .
Epithelial cells are those which form an epithelium (outer layer)

What's synapse ?

What's synapse ?

It's not in the syllabus ! It's for AS

Thank you so much, you cleared my confusion.

But.......it's.....wait wut..?..

Dude, It's in the MS lol
Biology 2013/O/N Paper 31 Question 5 part (ii) CHECK IT OUT if you want

P.S
oh my god. man they are so wicked...
how could they even..
ugh nvm :c...

Can any one of you be kind enough and list out the important/most frequently asked half ionic equations?
TBH, I am not that good with half ionic equations, even though I know how to work them out, I still am planning to memorize the common ones to save myself some time
For ex: Half ionic equation for Oxygen in electrolysis is commonly asked:
.. any more like these? (2O2 → O2 + 4e-)

Thanks in advance

Yes I do. I mean have this learner guide for biology that's really useful if you want but I just don't know how to send it to you here :c...
If you know how tell me so that I can send it to you!!
