I put cervix??
nah thats wrong, the cervix is the part inbetween the actual vagina and the uterus. The answer is either vagina or vaginal wall or something like that

Have a look, leave some comments and i'll update any errors.

4. guys i swear the question about the eyes is paper 2 stuff?
5. The egg cell divides by mitosis after fertilisation, not meiosis
6. how would you just measure the number of eggs. i put measure the volume and concentration of nutrient solution before and then after like a week check if you see if the volume has decreased. if it has then the egg would have absorbed the nutrients

I did the same thing except S. I said the pH in the test tube should be constant as if it is alkali or acidic then eggs will die. You would probably get 6 tho

*edit* I also said taken from the same species of mammal rather than the exact same mammal *edit*

8. Hi guys, this is my first post on the student room but I'm gonna set some confusion straight!

Firstly the answer is is 0.0075 as the distance given needed to be converted from cm into m, as the speed was given in metres a second, not centimetres a second

The anomaly was Thomas as his was the only heart rate that decreased before exercising.
Athletes have lower heart rate because they have much thicker and stronger heart muscles.
Adrenaline prepares body for flight or flight and increases heart rate.

Ovaries
Fallopian Tube
Uterus
Vagina

Males determine sex as they have Y chromosome

Yeah it said "What is the speed, in cm's/second" Didn't it? In which case it was 0.75
No dude it asked for time taken to travel in seconds, not the speed
10. It was an awful paper.
What do you think we will need out of 180 for an A?
And for an A*?
11. hi guys about the 0.0075 , 0.75 im pretty sure the units given were "seconds" so doesnt that mean that 0.0075 is actually the right answer. plus i feel like almost 1 second would be too long for a nerve impulse in the body
12. Nerve impulses travel at around 120 m/s if you look it up. It would not take 3/4 of a second to travel 90 cm. The answer was definitely 0.0075
13. Yeah thats what i thought
14. Hey did anyone know what the question was for the anomaly regarding heart rate? I put Megan, however many people put Thomas...
I don't really think it matters hahah, but it was the only one I was unsure of...

I'm pretty sure the amount of time was specified (one minute)
It was

its thomas, his heart rate at rest was 90 something and just before the race it dropped down to 70

Labelling is paper one and things like accommodation of the eye is paper 2.

Yeah I put Megan as well, I thought when I read people saying it's Thomas I must've just not read the question properly
