Fat contains nine kilocalories per gram.
Assessing the health status of the patient before conduction an exercise test is important because the patient may have health conditions that would interfere with the exercise test.
So we know that 40% of the 35 males are wearing sungalsses
40%=40/100=2/5
'of' means multiply
2/5 times 35 malses are wearing sunglasses
70/5=sunglasses
14=sunglasses
so 14 out of 56 to percent
14/56=0.25
answer is 25%
Answer:
The skin
Digestive tract
Vagina
Mucous membrane
Explanation:
The skin prevents microbes from entering the body
Digestive tract e.g. stomach acid is a natural defence mechanism
The vagina is acidic and this prevents harmful bacteria from growing with it's own flora.
Mucous membranes e.g. lining of the mouth, nose, eyelids are all defense mechanisms.
