The amino acids in a colon can be in multiple different orders, even those there’s twenty amino acids they can be rearranged and different amino acids can be in combination in a codon, hope this helps!

a² + b² = c² where a and b are the two shortest sides of a right angled triangle and c is the length of the hypotenuse, you might want to look up a diagram to help you understand this. Let me know if you need anymore help!

There are so many ways to revise and really everyone revises differently so it’s best to explore lots of techniques and see which ones work for you. Personally I like to take notes from a textbook by condensing/simplifying them, make mindmaps, make posters, make myself little revision quizzes, make flash cards (I used the app quizlet a lot) and my number one revision technique is exam papers and p... more

1st Paragraph: introduction summarising all your points, what was the Reichstag Fire if you can remember the date that’s a bonus, the same for the night of the long knives. 2nd Paragraph: Why was the Reichstag fire important to hitler coming to power? 3rd Paragraph: Why was the night if the long knives important? 4th Paragraph: conclude, which was most important and why. Use the line “I think... more

(^ means “to the power of”) For example: x^2 + 6x - 10 We halve the number before the x and put it into a bracket with the x and square the bracket as below. (x + 3)^2 We don’t want the 3^2 so we subtract 9 (3^2 is 9). (x + 3)^2 - 9 Finally keep the number from the original equation the same. So, (x + 3)^2 - 9 - 10 Final answer = (x+3)^2 - 19 It’s gets a little harder if you have a n... more

Successive ionisation energies are ionisation energies one after the other so for example 1st, 2nd, 3rd and 4th successive ionisation energies.

First you need to make the denominator the same (the number in the bottom of the fraction). Once they have the same denominator you can add them together. For example: 3/4 + 5/6 = 9/12 +10/12 = 19/12 To change the denominator you must multiply the top (numerator) by the same factor as the denominator. 3/4 —> 9/12 because you multiply 4 by 3 and 3 by 3. If you need anymore help with this let me... more

A quotient is just a fraction so adding 2/5 and 4/5 gives 6/5 or multiplying them forms 8/25 or dividing 2/5 by 4/5 gives 1/10

The consist of multiple atoms. For example a monoatomic ion would be an ion that consists of one atom such as Fe2+, Na+ etc. A polyatomic ion could be a sulphate (SO4-2) ion or a nitrate ion (NO3-).

Multiply by 100 0.86 x 100 = 86%
