Hey! I'm Steven, 18 years old and I'm studying Biochemistry at Durham University. I love tutoring people, to put it simply. At my college i was a tutor to a student in the year below me for chemistry and growing up with a younger sister assisting people with work has been part of everyday life. I'm friendly, enthusiastic and very understanding of any questions; if I hadn't had the help I hope to provide for my exams then i wouldn't be studying at Durham!
Reading Biochemistry, it may come as no surprise to hear biology and chemistry are where my passions lie. However after studying them at A-Level, maths and especially english still hold a firm place in my interests and i would love to help in those areas as much as possible; my English A-Level was my most enjoyable!!
As a teacher i think it important not to spoon feed anyone; whether it be for the generic reasoning of "they wont learn anything" or my belief that at times it can be overly helpful, even condescending. I would look to guide students, help them and hint them so they acheive the answers themselves. Obviously, when an answer is needed i would be more than happy to show them the way, so they are prepared for another, similar question. I am a very patient man, and rushing students through answers is not who i am. If a job's worth doing it's worth doing well.
I'd be happy to help any student who thinks i would be able to do so, and my enthusiasm for my chosen subjects is bound to rub off on anyone. Hope to see you all soon!

I believe the best way to approach this question is to look for frameworks shared by both texts, and directly compare the ways they are used, as they are often provided in a different context or offer an alternative attitude. The formemtioned attitude is perhaps the key to this question, as discovering each framework's intentions leads to linking this to the text as a whole and comparing their ultimately differing views.see more
There are three things to consider every single time relative reactivity is unknown; atomic radius, shielding, and number of electrons. The reactivity is the halogens ability to gain an electron, so number of electrons already in the atom plays a vital role. Chlorine has more electrons so repels a reacting electron with greater force than fluorine, making it less likely to react.
Fluorine also has fewer electron shells than chlorine, so there are fewer electrons between the positive nucleus and the reacting electron to essentiallly block, or weaken, the electromagnetic attraction. This is shielding.
Lastly, fluorine is much smaller molecule than chlorine, and the shorter distance, or radius, between the nucleus and the electron again makes it more likely to attract the electron and react to gain a noble gas configuration.see more
The main bonding in DNA which renders the double helix structure so stable is that of hydrogen bonds. Between the complementary base pairs, hydrogen bonds connect the two strands of the helix. There are 3 H bonds between Guanine and Cytosine and 2 between Adenine and Thymine. As well as this there are hydrogen bonds between the bases and surrounding water molecules, and this combined with the even stronger phosphodiester bonds in the sugar phosphate backbone make DNA very stable.see more
