NOTE: Almost all subjects have different rules regarding rounding off and significant figures. I'll be using the rules that I usually apply in school.
Marcus:
$35.99 * 5.5% = $1.98
$1.98 + $35.99 = $37.97 (Total Cost)
Tia:
Since it wasn't specified if the coupon was applied before or after tax, we're going to assume that it was applied before tax because that's usually how it works.
$39.99 * 15% = $5.9985 or $6.00
$39.99 - $6.00 = $33.99
$33.99 * 9% = $3.0591 or $3.06
$33.99 + $3.06 = $37.05 (Total Cost)
Difference in Marcus and Tia's Total Cost:
$37.97 - $37.05 = 0.92 cents
the answer is worsted WOOL I am taking the test right now and the answer choices are off
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.
