The body's first line of defence against shifts in pH is its acid-base buffer systems.
What is acid-base buffer system?
- The proper balance between the acids and bases in the body's extracellular fluid is crucial for the normal physiology of the body and for cellular metabolism.
- The first lines of defence are immediate, consisting of the various chemical buffers which minimize pH changes that would otherwise occur in their absence.
- The pH of the intracellular fluid and the extracellular fluid need to be maintained at a constant level.
- Proteins are denatured i.e. their 3D structure is disrupted, causing enzymes and ion channels to malfunction.
- An acid–base imbalance is known as acidaemia when the pH is acidic and alkalaemia when the pH is alkaline.

1) Henry Cowell played his signature tone clusters on D) the piano. He came up with his <span>innovations in the piano pieces, when he developed </span>“tone clusters”. Such an achievement came to his mind somewhere between<span> 1912 and 1930 when Cowell was looking for new sonorities.
</span>
2) Western composers were heavily influenced by non-western music during the late twentieth century because of C) a sense of anti-nationalism. Every talented person wants to erase boundaries of common knowledge and find a source of other culture so that they could combine all their experience into something new.
3) <span>Edgard Varese defined music as B) organized sound. Varese brought a concept of a perfect sound in simple words "what is music but organized noises?". When listening to his music, it's clear that it is meant to emphasizes timbre and rhythm. He gave to a musical structure, which he considered as perfect, the name - "organized sound".
4) </span><span>Many Indians talas, or rhythm cycles, use additive meter, which means C) measures increase in size as the piece progresses. There are two musical terms that can be helpful while distinguishing two types of both rhythm and meter- additive and divisive rhythms. In contrast to additive, divisive rhythm is a rhythm in which a larger period of time is divided into smaller rhythmic units.
5) </span>Systematic, or minimalist, music is generally C) tonal. In music, tonality<span> is when </span>pitches<span> and/or </span>chords are arranged in a hierarchy (it is systematic). The main characteristics of minimalism in music are the presence of <span>a steady pulse, clear tonality, and insistent repetition of short melodic patterns.</span>
