New biosensors, applied like a temporary tattoo to the skin, can alert serious athletes that they are about to "hit the wall" an

d find it difficult to continue exercising. These biosensors monitor lactate, a form of lactic acid, released in sweat during strenuous exercise.
Which of the statements below is the best explanation of why athletes would need to monitor lactate levels?
A. During anaerobic respiration, lactate levels increase when muscles cells need more energy, however muscles cells eventually fatigue, thus athletes should modify their activities to increase aerobic respiration.
B. During aerobic respiration, muscles cells produce too much lactate which causes a rise in the pH of the muscle cells, thus athletes must consume increased amounts of sports drinks, high in electrolytes, to buffer the pH.
C. During anaerobic respiration, muscle cells receive too little oxygen and begin to convert lactate to pyruvate (pyruvic acid), thus athletes experience cramping and fatigue
D. During aerobic respiration, muscle cells cannot produce enough lactate to fuel muscle cell contractions and muscles begin to cramp, thus athletic performance suffers.

Fecal transplants is idea for replenishing of good bacteria in the body due to resistance from prolong use of antibiotics. It is specifically for treatment of resistance of antibiotic therapy due <u>C. difficile colitis. </u>

In patient  above 65, infected with  C. difficile colitis and  with resistance to antibiotic especially oral vancomycin, fecal transplant is applied to  effectively cure this.

The transplant is conducted through the Colonoscopy. Where the fecal is discharge into the colon  as the Colonoscope is withdrawal from the colon

.

Since natural  good bacteria are present  in fecal and have no effect on the good bacteria in the body, this procedure increased the total number of bacterial(microbiota),by stabilizing the the microbiome and curing the patients.
