Explain two disadvantages of specialisation.

Vulnerability, whether it be an employee, firm or country who specialise, producing only one good can be a risk if that industry were to collapse. An example of this is the increase in unemployment in the south of England resulting from deindustrialisation.Quality of output may in fact decrease as repetition can cause boredom and workers may start to make mistakes.

Why does excessive consumption of alcohol lead to negative externalities ?

The private consumer does not consider the effect that their excessive alcohol consumption has on a third party and so the private benefit outweighs the social benefit. There is a welfare loss to society from the over consumption and over valuing of alcohol above the socially optimal level.

How do you form the future tense in Spanish?

Great question! The future tense is really useful because it allows us to talk about future events and so can be included in almost any GCSE writing task!We can use the future tense to talk about events happening tomorrow (mañana) or in 2021 (dos mil veintiuno).To form the future tense, we first need to know the infinitive of the verb. The infinitive is the verb in its simplest form before any endings have been added or changed. For example, hablar (to speak), comer (to eat) and vivir (to live) are all infinitives. We can spot infinitives because they end in -ar, -er or -ir.Once we know the infinitive, we add on the future tense endings onto the end of the infinitive. These are: é, ás, á, emos, éis, án. All except the 'we' first person plural ending, have an accent. Now let's repeat the endings together to help remember then.So for example, 'I will live' would be vivir + é = viviré.Now your turn to try one - how would you say 'We will go to Spain?' - Ir + emos = Iremos, 'Mi familia y yo iremos a España'. Fantastic, well done! Any parts which you find tricky to understand, or any questions?

How can I differentiate prokatyotic and eukaryotic cells?

The main difference between these two cell types is that eukaryotic cells have their DNA collected inside the nucleus, while prokaryotic cells lack nuclei. Instead, they have a circular piece of DNA called the nucleoid anywhere in the cytoplasm, and other smaller, ring-shaped DNA pieces called plasmids.There are, of course, many other ways to tell them apart. For example, the organelles they contain (prokaryotes lack many organelles that are normal in eukaryotes, like the endoplasmic reticulum, mitochondria or the Golgi apparatus), or their level of organisation (prokaryotes are unicellular organisms, like bacteria; whereas eukaryotes can organise into multicellular living beings, like plants, fungi or us!).

Complete the square for x^2 + x - 6.

First, let us separate the constant term and complete the square for (x^2 + 1x).
x^2 + x - 6 = (x^2 + x) - 6
Now, let us halve the coefficient of x.
0.5 of +1 = +0.5
Write (x )^2 with half the coefficient of x before the end bracket then subtract the square of half the coefficient of x.
(x^2 + x) - 6 = [(x + 0.5)^2 - 0.5^2] - 6 = (x + 0.5)^2 - 0.25 - 6 = (x + 0.5)^2 - 6.25,
which is the required completed square form (x + p)^2 + q.
Often, a GCSE question will ask what the minimum point of the graph is - and the minimum value of y is -6.25, and occurs when (x + 0.5)^2 = 0 so x=-0.5. Hence, the minimum point is (-0.5, -6.25).

Understanding Poetic Metre - What, Why, and How?

When listening to music at home, you may find yourself tapping your feet along to the beat - or rather, to the rhythm. Rhythm is the most essential part of all the music you listen to, and it's at the heart of every song you love. One definition of rhythm is that it is 'the pattern of regular or irregular pulses caused in music by the Occurrence of strong and weak melodic and harmonic beats' - essentially, rhythm is the part of the song that makes us move, dance, sway - how you bop your head up and down, by mixing up different kinds of pulses. The same can be applied to poetry. Each poem has a unique rhythm, which, rather than making us move in a certain way, makes us speak and deliver the poem in a certain way. For example, when we read 'Sonnet 18' of Shakespeare, we hear a particular rhythm:'Shall I/ com PARE/ thee TO/ a SUM/ mer's DAY?/Thou ART/ more LOVE/ ly AND/ more TEM/ per ATE'Here, you can visually see the rhythm of the poem. The parts in bold are where you stress what you're saying - almost the vocal version of a foot tap, or a clap, to your favourite song.Rhythm is, however, a wider term. We can be even more specific when we are analysing the rhythm of poetry. Rhythm is created by the poets' use of a particular poetic metre. A metre is a pattern in poetry made up of what we call poetic feet. Every foot is made up of stressed (emphasised) and unstressed (not emphasised) syllables (remember, you can work out what a syllable is if you clap your hands along to a word; happy is two syllables, because you can break it up into two claps, whereas sad is just one syllable). Depending on the type of foot that is used, and how many times it is used in a line, we get a different metre and therefore a different rhythm. There are five main types of feet in literature:1. Iambic (one unstressed syllable and one stressed syllable - daDUM)2. Trochee (one stressed syllable and one unstressed syllable -DUMda)3. Spondee (two stressed syllables - DUMDUM)4. Anapest (two unstressed syllables and one stressed syllable - dadaDUM)5. Dactyl (one stressed and two unstressed syllables - DUMdada).If we think back to the line we used earlier from Shakespeare, we can now work out what type of poetic foot is used:'Shall I/ com PARE/ thee TO/ a SUM/ mer's DAY?/ Thou ART/ more LOVE/ ly AND/ more TEM/ per ATE'. Each little part of the line - the foot- is made up of an unstressed syllable and a stressed syllable - deDUM. This is iambic. Now if we count up how many of these feet are in each line, we can see this happens five times. So we have five iambic feet in each line, and this forms the metre. There are special words that we can use to describe the number of feet in each line in poetry:1. Monometer2. Diameter3. Trimeter4. Tetrameter5. Pentameter6. Hexameter7. Heptameter8. OctameterSo in Shakespeare's 'Sonnet 18', we know that the metre he uses is iambic pentameter, and this forms the rhythm of the poem. Working out the metre of each poem is immensely helpful in telling you new things about it. For example, if you clap out iambic pentameter - a small clap and a big clap - you can hear that it sounds like a heartbeat. Perhaps Shakespeare uses iambic pentameter in his love poetry because it is the closest to the rhythm of his heart, making the poem all the more romantic.

When do I use the subjunctive in Spanish?

The subjunctive is a mood, not a tense. The other ‘moods’ would be the indicative and the imperative. The subjunctive also exists in English (“If I were rich, I would…”) but it is much more common in Spanish. It is used when talking about desires, emotions, doubts and the unknown. All of this might seem pretty abstract, but luckily there’s a handy acronym you can memorise to remember all of the situations in which we might need to use the subjunctive mood, W.E.I.R.D.O.
W – wishes and desires (espero que tengas un buen día – I hope you have a good day)E – emotions (me alegro de que te guste – I’m glad you like it)I – impersonal expressions (es importante que leas este libro – it’s important that you read this book)R – recommendations and requests (recomiendo que tomes más agua – I recommend that you drink more water)D – doubt (dudo que tengas mi dirección – I doubt that you have my address)O – ojalá. This is a bit of an odd one out, but you must always use the subjunctive when using ojalá, which means I hope / I pray / If only (ojalá que él recuerde – I hope that he remembers).
This is a simple way of remembering most of the situations in which we need to use the subjunctive. Especially when writing essays in Spanish, ask yourself every time you use a verb if is complies with one of the W.E.I.R.D.O situations. If so, you need a subjunctive. Using subjunctives can be a good way to boost marks for grammar and sophistication in A level exams.

What is the critical angle of a beam of light leaving a transparent material with a refractive index of 2?

Total internal reflection occurs only when light travels from a medium of high refractive index to a medium of low refractive index. This is the case for our problem (glass to air boundary, n=2 and n=1 respectively). Remember that when light moves from a high to a low refractive index, the incident and refracted rays are not parallel - the refracted ray is bent way from the normal to the surface. Now imagine we take the incident ray and increase the angle of incidence until light "bends" inwards.The critical angle is the minimum angle of incidence for which total internal reflection occurs. From Snell's Law we know that: n1 x sin(θ1) = n2 x sin(θ2). Now, setting θ2 = 90deg. (angle of refraction) and rearranging we get: sin(θ-critical) = n2/n1.

What is the difference between the "passé composé" and "imparfait" tenses?

Passé composé and imparfait (or imperfect) are both past tenses, but are used in different circumstances.
The imparfait is most commonly used when speaking about: events that are not specifically defined within a time bracket, that are continuous, e.g. "I was going to the supermarket" becomes "J'allais au supermarché."a routine in the past, e.g. "I took the bus every day" becomes "Je prenais le bus tous les jours."secondary events, e.g. "I was closing the door, when I heard a noise." becomes "Je fermais la porte, quand j'ai entendu un bruit."
The passé composé is most commonly used when speaking about:the recent past, e.g. "Yesterday, I went to the supermarket" becomes "Hier, je suis allé au supermarché."a specific, pointed event, e.g. e.g. "I was closing the door, when I heard a noise." becomes "Je fermais la porte, quand j'ai entendu un bruit."
