Practice questions! Exclusive discount!

Hello all you lovely revision gurus,

I hope exam prep is going well for everyone this year AND youre not getting too stressed out!

I wanted to let everyone know about a unique opportunity for a 20% discount for hannahhelp users for the revision site https://www.savemyexams.co.uk/

CODE: han20

This site has a tonne of resources for you to revise from: not only does it provide all the past papers in one place but has additional mock papers on top of that so you can take your revision even further! They've divided up all their material into managebale topic-based chunks as well, which you know I'm a fan of.

I could not get my hands on enough practice questions when I was doing my revision and would have been all over this site!

Apparently it's not just me who thinks past papers are a good idea, but, according to this researcher, studies show that practising past papers is the one thing all top students have in common!

So that's my little good luck gift to you all, use it wisely and stay clam!

Happy to have helped

Comments

Hi!

Please feel free to comment- extra information, corrections, helpful links and feedback are always welcome. But please be aware of how you phrase your comments; what you put out into the world is what you will receive from it. Negative energy on the internet harms the beauty of life and it's so sad that people should be fighting each other at such an important time for your futures.

 I appreciate all of you who stick up for me, it really does mean a lot, but I recommend not being aggressive to trolls as it only makes them stronger.

Apologies for anyone who has to read offensive comments, but unfortunately I don't keep up with my comments apart from corrections and legitimate queries so I don't delete or respond to unhelpful negative comments.

If you have commented honestly and someone has sent you an unpleasant reply, please know that they only represent their own view and if you were just trying to do or say something helpful or kind that most people will respect what you have said (but you will unfortunately tend to only get a certain type of person reply).

I really hope that no one with something helpful or kind to say is put off of commenting, because something I love about this blog is the way that everyone comes together to help each other out. Your greatest tool in an Internet conflict situation is that you don't need to read something if it is unpleasant and not designed to be helpful.

With that out of the way, thank you to everyone who helped this year (both with info and positivity), and I hope you get the results that you wanted. And welcome/welcome back to anyone crusing the site this year.

Positivity and serenity to all,

Hannah Help o

Nepal and Ads

Hello all loyal friends and fresh new faces,

I hope that you are keeping zen about your upcoming exams- I'm here for ya.

Since January have been in Nepal! Volunteering with Restless Development helping to improve livelyhoods and employment prospects in poverty stricken communities- check out my pics for a revision brake or give a little donation if you can (even a couple of quid goes a long way).

It was an amazing experience and our work benefited so many people! Unfortunately though, there was nooooo wifi what so ever (I know), so I haven't made any adjustments in a while.

So whilst I'm doing this keep an eye out for any helpful points in the comments (thank you so much for everyone who takes the time to comment feedback and corrections, keeping hannahhelp alive).

One more point, which is that I am going to put some ads on the blog.

Though this may be controversial I hope y'all understand: I am trying to get together money for a plane flight to Africa so that I can volunteer there with a charity working to prevent the spread of AIDs in the young population.

Do let me know if you think they are obtrusive or affecting your revision, because I can always take them down, but if not it's a win win- you're getting hannahhelp and I'm getting p ;)

Remember to work hard and relax hard- no slacking, no stressing. Ok?
Best of luck,
Hannah x

Thanks

Hello all,

I just wanted to say a massive massive thank you to everyone who has commented on my blog over the years.

I've just tried to filter through some of the comments to make final corrections, as I have finished my schooling career so probably won't revisit hannahhelp to make edits in the future, and it has reminded me how lovely you all are.

People have written me the nicest praises and thanks that you could imagine and I am so grateful- I am just sorry that I can't reply to them all individually any more because there are so many! Just know that your words have touched me and I am thankful.

Corrections have been so helpful too as firstly (as you probably know) I can't really spell haha and secondly they have ironed out mistakes that I made. People have also added links and extra information, which has turned this from my blog into an even richer resource, acting as a hub for knowledge.

One of the best things that I have seen is people asking questions and other readers answering them! Asking questions gives an opportunity for clarification, not just for the person who asked but for everyone reading; and people who have given answers I commend you for giving your time to help me and everyone else.

I really hope that this culture of adding, debating and aiding continues even after I completely stop editing :')

Thank you all so much.
Happy to have helped ;)
Hannah.

Apology

Thank you guys for all your comments that are coming in, I really do appreciate it.

Unfortunately I am also doing exams at the moment and there just isn't time to reply to them all.

I promise I will amend and converse as soon as I have the time!

Best of luck for your GCSEs!

Hannah :)

2.90 understand the sources, roles and effects of the following hormones: ADH, adrenaline, insulin, testosterone, progesterone and oestrogen.

ADH
Lack of water is detected by the hypothalamus in the brain, it causes the pituitary gland to produce Anti-diuretic hormone, or ADH. This makes the kidneys to reabsorb more water- so less is lost from the body.

Adrenaline
Produced in the adrenal glands in stressful situations. Heart rate quickens to increase the flow of blood to muscles- this means that they can respire more (as there is more oxygen available) to provide energy if you need to 'fight or flee'.

Insulin
Produced in the pancreas when there is too much glucose in the blood. It stimulates cells to convert the glucose into glycogen which is a from that can be stored. This means that you always have the right amount of glucose in your blood.

Testosterone
Produced in ovaries in girls and testicles in boys. Plays a key role in puberty, developing sex organs and inspiring hair growth.

Progesterone
Produced in the ovaries it maintains the lining ready for pregnancy, and continues to do so if the egg is fertilised.

Oestrogen
Produced in the ovaries, it is controls other hormones to regulate the menstrual cycle. It stops the production of FSH and starts the production of LH.

There are things that make you more likely to have a mutated gene, these include: ionising radiation and chemical mutagens like some chemicals in tobacco.
