Gcse core science aqa predictions

I think 6 markers for core science paper 1 (on the 17th) could be:
How drugs are tested
Reflex actions
Crude Oil
Heat Transfer
What do you guys think? (paper 1 only)

A lady on youtube has predicted this:

C1
P1
But tbh I'm just going to cover everything anyway

PLEASE explain what the doppler effect & redshift are! I've been looking everywhere and don't understand

How did you come to these conclusions may I ask?

I think this is basically what it is:

object moves away from observer: light waves stretch out so the wavelength becomes bigger
object moves towards observer: light waves squash so the wavelength becomes shorterThe wavelength affects the colour of the light (red has longest wavelength and violet has the shortest)

By looking at previous past papers and identifying the patterns of questions and topics they included. Also, by looking at the examiners report to see what the examiners thought the students didn't do so well on. This makes it likely that they will include those topics on the this years exams and next years too see if their teachers have taught them the new stuff that students didn't do so well on last year.

Are you doing triple or double science? So Unit 1 or unit 5&6?

A lady on youtube has predicted this:

C1
P1
But tbh I'm just going to cover everything anyway

My predictions:

Biology:
GM
Drugs
Hormones
The carbon cycle

Chemistry:
Hydrocarbons
Emulsions
Ethanol

Double science, unit one.
B1, P1 & C1.

Oh so you're a year 10? Are you doing 2 core papers that contain all 3 science in? I'm doing double aswell, but I'm a year 11 and I'm re-sitting it from laast year. I got a B last year, but want an A aha.
Do you know if the re-sit paper is the same as the GCSE core you're doing?

yep its the same!

btw can you explain genetic modification please?

Ahh I don't even know! If I find out I'll let you know - do the same plz!

All his videos are soo good. Put the speed on 1.5 to get through them quicker x

Basically
Enzyme is used to cut gene for insulin from DNA
Enzyme is used to cut plasmid out of the bacterial cell and insert insulin gene into bacterial cell. Allow the insulin to reproduce and it can be harvested.
