ITGS HL Students.. What exactly is the difference between a smart home and an intelligent home? Its one of the terms listed in the last page And in line 57 it is stated that some preliminary findings suggests that a smart home may evolve into an intelligent home that customizes itself to suit the behaviour of people in the house. I mean, there's some form of definition there for it. But I tried looking up some info on intelligent homes and the difference between them and smart homes, cuz I thought maybe that would come up somewhere in the exam, but I cant really find any solid information. If anyone cares to elaborate or has any more useful i…

Hello everyone, Since we have paper 3 on the 17th How is everyone doing with the case study? I've done research, but still think I'm missing some information that might be helpful for the exam. For anyone who sat paper 3s before? What is important to consider? Because I didn't sit one for my mocks, we only did paper 1 and 2 for the mock exams. And also regarding the Smart Home 2016 case study.. What have you guys included as part of your research? I mean, what do you think is important to know and keep note of for the exam?

HL Biology (Option G): What is the definition of a hormone, what different types are there (with an example of each) and how do these differ in their modes of action? A Hormone is defined as a chemical messenger secreted by endocrine glands into the blood and transported to specific target cells. You need to memorise all the parts of this definition off by heart! Types of hormone include: 1. Steroid hormones such as Oestrogen and Testosterone 2. Peptide hormones such as Insulin, Glucagon and Anti-Diuretic Hormone (also known as Vasopressin) 3. Tyrosine derivative hormones such as Thyroxine (T4), Adrenaline and Noradrenaline (Obviously there are other examples!) Steroid ho…

HL Chemistry: In Redox chemistry, what is happening at the cathode and anode (reduction or oxidation?), and which is positive and which negative in... A) a voltaic cell B) an electrolytic cell? A) In Voltaic cells, electricity is produced by a redox reaction. Oxidation occurs at the anode (which is negative) and reduction occurs at the cathode (which is positive). B) In Electrolytic cells, oxidation occurs at the anode (which is positive) and reduction occurs at the cathode (which is negative). Voltaic Cells - these are made of two half-cells connected in a circuit by a salt bridge. The salt bridge is usually made using filter paper dipped in saturated KNO3. Each half-ce…

Biology SL/HL: Describe the 4 structures of proteins There are four main layers to protein structure that you need to be able to describe: Primary - this refers to the amino acid sequence of a protein. The amino acids are held together by peptide bonds and bound together they form the polypeptide chain. Secondary - these are highly regular sub-structures such as alpha helices and beta pleated sheets. Parts of the polypeptide chain move to form these structures which are held together by the formation of hydrogen bonds. Tertiary - the three dimensional structure of a protein as it folds up. This is driven by hydrophobic interactions and involves specific tertiary inte…

League of Nations was not the most successful post-war innovation. It relied on the fact that everyone would want to get involved in preserving the world peace. The ideal was beautiful, however, rather unrealistic and, as it turned out, the League failed at its most basic aim: preventing another war from breaking out. But why? Absence of major powers: Germany and USSR were not allowed to join (so it provided a possiblity of them plotting with each other as "outcast nations") and USA refused to join. Lack of USA was bad both economically and psychologically for the League - it lacked a strong nation that could have held it together. Decisions had to be reached unanimousl…

The law is based on bodies of mass. It states: The force of attraction between two forces is directly proportional to the product of the two masses.The force is also inversely proportional to the square distance between them. So: Putting these two together gives: In order to make them equal we need a constant (which is G. 6.674×10-11 N m2kg-2). The final equation results in: Now, how is this linked to Coulomb's law? Well they're both extremely similar but for charges instead. However please remember that like charges repel and different charges attract. A common mistake is that they'll always attract just because that's what happens between two bodies of mass. So th…

Italian Unification was largely influenced by 5 individuals but all of them played different roles with varying degrees of significance. These Individuals were Cavour, Mazzini, Garibaldi, Napoleon III and Victor Emmanuel II. It is also important to take their intentions into account. Cavour: He played no role in the revolutions Pre 1848 because he felt that they were counter productive. His main contributions came from when he was in power beginning in 1852. Economic contribution:During the 1850s trade increased 300% in Piedmont. Piedmont had 800km of railway track by 1860 which was one third of all the railway track in Italy at the time. Some of these tracks went throug…

There are 3 principles of the Biological Level of Analysis and you have to know them all. They can come up both in the section A of Paper 1 and in Section B. They are also the very basis of the whole LOA. The principles are as follows: 1. Some behaviours are innate (inborn) because they are genetically based - this means that, at least to some extent, our behaviour is determined by the genes we get from our parents. Therefore, there will be similarities in behaviours of the closest members of the family (parents, children, siblings). A study to demonstrate it: Bouchard et al. (1990) - Minnesota Twin Study (remember that it was not a single study, but a series of differ…

HL Biology: Why might you want to cut a strand of DNA with a restriction enzyme? And what unique feature may be present at the ends of the cut strands? A restriction enzyme, also known as an endonuclease, is used to cut strands of DNA specifically for gene engineering. The reason for this is that restriction enzymes are known to always cut DNA at particular sequences in a very specific manner. These are known as target sequences. The unique feature which may be present at the end of cut strands are 'sticky ends'. These are overhangs on the end of DNA chains where you have unpaired nucleotides and which are most commonly created by restriction endonucleases. They are fr…

Germany didn't exactly feel defeated in the war - it occupied territories in France and Belgium defeated Russian and wasn't invaded. No wonder why Germans could feel unhappy with what ToV offered them. They were not included in the negotiations of the terms, they were simply forced to sign - this in itself was degrading for a country this important on the international arena, and also a heavy blow to German pride The war guilt clause - Germany was essentially blamed (as the only country) for the outbreak of the War, and they didn't believe it was justified The Treaty was not exactly based on Wilson's Fourteen Points - Germany expected it to follow it closely and it didn't…

SL/HL Biology (Option E): What are three main differences between rod and cone cells in the retina of the human eye? There are three main differences you need to be able to name between the rod and cone cells of the eye: 1. LIGHT INTENSITY - Cones are used to see in bright light and Rods are used to see in dim light. 2. WAVELENGTH SENSITIVITIES - There are three types of Cone which are sensitive to red, blue and green light respectively, and which are used for your colour vision. Conversely, Rods have only one type which is sensitive to all visible wavelengths. You don't need to be able to state it in the exam, but rods are basically for your black/white vision in poor li…
