3.sometimes we use them interchangeably but they really are two very different things - salt and sodium. Explain their differences and their impacts on health and particularly hydration and fluid status.

4.What does potassium do and where do we get it?

3. Table salt is the compound containing sodium and chlorine in form of ions bonded through ionic bond.

Most of the sodium about 90% of sodium we get come from salt where are salt contain about 40% of sodium where the rest is chloride.

Sodium in ionic form (Na⁺) is present in body fluids and cells maintain the osmotic balance.

Sodium ion (Na⁺) concentration determines the membrane potential which is required for transmission of nerve impulse.

Sodium ion in blood maintains particular osmolarity and is required for fluid and electrolyte balance which is implemented by hormonal control over kidneys.

4. Potassium (K⁺) is also similar to sodium in its valency and along with sodium ion it maintains the normal resting potential of the membrane. Na⁺-K⁺ pump is the Ion channel which utilizes ATP for the transport of sodium ions towards outside and influx of potassium ions. Both Na⁺, K⁺ not only maintain fluid balance but also should be maintained at constant concentration for many physiological functions of the body.

'The terms numeracy and mathematics are often used interchangeably, but in fact they are very different concepts' (Grimley, 2016). Your essay should be informed by your understanding of the two concepts: mathematics and numeracy. Weeks 1–4 of your learning materials will give you an understanding of both concepts and how they are crucial to one’s understanding of the world around us. You are required to support your discussion with examples of everyday (maths) phenomena and identify where mathematical and numeracy...

There is something about faces, we can usually identify them very quickly, under many different conditions, however there are known variables which affect this ability. Two conditions “target present” and “target absent” are an important feature of face detection and recognition studies. There is, however, no suggestion that accuracy of identification might vary depending on whether or not the target is available. Analyse some data from a simple face recognition experiment, where participants were shown 20 short video clips of...
