Explanation:
Answer: 83 inch²
Explanation:
First find the area of the rectangle:
= Length * Width
= 8 * 5
= 40 inch²
Then find the area of the first traingle:
= 1/2 * base * height
= 1/2 * ( 4 + 4) * 7
= 28 inch²
Then the second triangle:
= 1/2 * base * height
= 1/2 * (2.5 + 2.5) * 6
= 15 inch²
The area of the polygon is the sum of all these:
= 40 + 28 + 15
= 83 inch²
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.
