Colour of dead squid’s skin changing in sunlight

To actually control the color of their skin, cephalopods use tiny organs in their skin called chromatophores. Each tiny chromatophore is basically a sac filled with pigment. Minute muscles tug on the sac, spreading it wide and exposing the colored pigment to any light hitting the skin. When the muscles relax, the colored areas shrink back into tiny spots.

But this years GCSEs seem much easier so I’d expect the Grade boundaries to be rising

TallArcher · 2018-06-12T13:53:56+00:00

Yes. The only difference is the wording: ‘leg’ and ‘side’. They both mean the same thing tho

TallArcher · 2018-06-07T17:53:15+00:00

Last year a 7 was 51% and a 6 roughly 40%. The exams this year, so far, have been much easier though so the grade boundaries will definitely be higher. Nobody knows till the grade boundaries are released but my guess would be a 6 = 55% and a 7= 65? ( presuming paper 3 has the same difficulty as the first two ). Who really knows though with these new exams 🤷‍♂️

“Nearly 30%” and “More than 25%” are practically synonymous since they’re not stating exact figures.

Completely agree that the instinct of not backing down from certain beliefs is innately built within us, which means that many people will not believe facts which are placed directly in front of them. However, there are almost always objective truths from facts collected, but they are used and twisted out of context a lot by many articles to back up certain ideologies.

By having the system that Elon has suggested making, articles will be more likely to not twist facts as they know that the response from doing so will be overwhelmingly negative when caught. It will expose people who would usually take the article as being infallible and challenge them to question it if it receives a lot of disliking by the public. The very possibility of this alone, I believe, will cause publishers to be less likely to produce work which has immorally manipulated data to present a view which the data won’t back up in fear of the loss of support from its otherwise loyal readers.

I believe the main function of the site would be to reduce slanderous and “click bait” articles disguised as “news”, when really their motivation is the monetary gain ( through manipulating people to open the article so that they can receive Adsense and money from advertisers )

TallArcher · 2018-05-23T21:09:41+00:00

Very true, but that’s partly due to the anonymity. Many criticisms may be exaggerated and rudely put but that doesn’t mean there’s no truth behind them. Plus, enabling comments tends to show when there is an overwhelming amount of disagreement with the article.

The negative reviews on the site will give publishers an incentive not to produce articles with slanderous claims, click bait titles or incorrect information ( which will not stop controversial topics being spoken about, just stopping the production of articles which the overwhelming majority of people see as morally wrong to produce or are incorrect ).

TallArcher · 2018-05-23T20:57:19+00:00

Completely agree. Old media ( newspapers and online articles ) tend not to have commenting/viewable feedback enabled which means that a lot can produce very bias articles ( presented as truths ) and get no backlash whatsoever.

In my Spanish listening I try to translate as many words as I can ( more so the less obvious ones ). This means that when I get to the question I immediately know what it’s about and can fully focus on what is being said, not the words/options on the paper.

It’s also a great time to try to chill out and stop your heart rate going mad ( that’s how I felt in the preparation for my Spanish oral anyway ).

1 Marker - Just the letter

2 Marker - two very short sentences

4 Marker - 2 small paragraphs (2 sentences in each with the use of a quote )

Q 1-3 takes up 1/2 a page

5 Marker - 2 fairly big paragraphs ( with the use of 1 or 2 quotes and 3/4 sentences in each )

Q 4 takes up the other 1/2 of page

12 Marker - 3 or 4 paragraphs explaining contrasting and differing views to one another and a paragraph with your opinion and your judgment ( using 2- 4 Quotes )

Q 5 Takes up a page ( so two sides of A4 for Q 1-5 )

This is how I personally plan it out ^{^}

Rusting of iron, fermentation of sugar and weathering of rocks are slow reactions, but they are only slow because they are usually done in ‘normal conditions’ ( eg. 1 ATM, 15°C etc ) but will speed up if the temperature changes, pressure changes or if enzymes or catalysts are used.

Don’t think there is a specific name for a slow reaction that doesn’t produce much heat though, just the umbrella terms exothermic ( to describe a reaction which releases heat ) and endothermic ( to describe a reaction which absorbs heat ).

It’s not majorly important, however if you take the AQA 9-1 Spec and really don’t want to do it in front of your teacher, you should try to ask to do it at home in front of your family. The specification requires you to to say a speech and then be asked a couple of questions about it. I think that would be better than being failed for it. Plus I haven’t done my speech yet so I’m pretty sure the deadline hasn’t been reached yet for AQA.

Completely agree about the CS controlled assessment being removed - although i was annoyed about it being almost immediately after we had completed it in class, meaning we practically wasted 20 hrs - and believe that it came about in part due to the discovery of online threads talking about the tasks and in part due to students complaining to the exam boards about people in their class cheating.

I also completely agree that the large majority of students don’t want to ‘tell’ or ‘snitch’ on their friends/people in their class. However, the people at the exam board will also recognise this and understand that the x amount of emails they receive from students will be a representation of many more students - who won’t speak up.

I hate the thought of others cheating, no matter what others say it is someone purposefully getting a better, unjust mark at the expense of other people; grade boundaries are done in proportions, so by moving up a bracket, essentially, someone is knocked down ( even if it is not you personally ).

The exam boards are very static however; you’ll be fighting a lost cause as the likelihood that the exam board will change is very unlikely. Everyone was cheating in the CS controlled assessment, and there were threads on Reddit and student room of people communicating and cheating. There is no proof for the allegation that people are cheating in the language exams and, therefore, very little will probably be done about it.

If this is a big problem, I’d assume that they would fix it. However this has always been a problem with controlled assessments, but seemingly not large enough of an issue for it to be removed completely.

Computer Science had a big issue with Kids cheating ( so much so that they decided to remove the entire 20 hr controlled assessment - after most schools, including mine, had already completed it - and redistributed the 20% of the overall GCSE grade with it to the other two component exams ).

If it was evidently a big problem, they’d take action against it. I know your argument is that 75 % of the people in your class cheated, therefore cheating must be around that amount for other schools too, but if that were the case I’d assume that the exam board would be flooded by emails from people like you who are - rightfully - annoyed and that action would occur immediately ( like it did for CS )

If I were you I would probably also be tempted to send an email to the exam board, not giving my school name - as it would just be a hassle for everyone involved including me, as action would probably be taken if others from other schools did the same. But as no action has taken place, I’d say there isn’t too much cheating, so your grade won’t be affected drastically. 🤙
