can someone plllzzzz help me...
how to calculate hatch rate of brine shrimp??
my exam is day after!!!!!

Hatch rate= no of eggs hatched/ time taken.

Rate is always as something divided by time. So it could be this too

Hate rate= no of eggs hatched after 24hrs

So the units might differ. Or it can be

Hatch rate= 1/(time taken for 10 eggs to hatch)

But this is practically difficult. So depending on the context or your experiment it might differ. It should be a sensible so as to compare with other results sensibly.

So that means lysosomes contain lysozymes?!

To anyone who needs it, here's the IAL June 2014 scientific article on COPD:

Here's the pre-released article. I'm not sure whether this is the one you're getting though.

for the habituation experiment these are some variables that must be controlled
age of snail
size of snail
species of snail
how will each variable affect the time taken to re-emerge from the shell?

The code should be the same as the code in your entry form/whatever.

Imagine getting the wrong article

thanks for reassurance , seriously feel panicked though!

I think i remember seeing you post on the u1/2 last year.. how did you end up doing if you don't mind me asking? and what are you aiming for?

Somehow I got 115/120 in both but that won't be happening this time!!

No worries mate, no point stressing I'm sure we'll be so prepared that the margin for failure will be tiny!

You probably did, I got a B kinda disappointed just because I left revision late for unit 2. Funnily enough i got the same UMS for both unit 1 and 2, so i'm only like 6 marks off an A.

I only need a B actually, so thats seems very achievable tbh.

You did fricking amazing, but im guessing your firm requires an A?
