Explain why there is a difference in the amount of oxygen taken in at rest and during the vigorous activity. ​
s2008m [1.1K]

Answer: During vigorous exercise your breathing rate increases in order to intake more oxygen

Explanation:  during vigorous exercise / activity the body needs more oxygen in order to produce energy so your breathing rate increases in order to reach the demand of more intake of oxygen , and your muscles work harder due to an increase in oxygen demand and how much oxygen the muscles take from the blood during vigorous exercises , BUT during rest we have normal rate of oxygen intake because your body is at rest at that moment .

One g of fecal matter was suspended in 99 ml saline solution (tube 1). After mixing gently but thoroughly, one ml from tube 1 wa
malfutka [58]

Answer: the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3

Explanation:

We know that; Gram negative bacteria looks  pale reddish in color under a light microscope from Gram staining.

therefore

There are 30 red bacterial colonies counted.

1 mL of from tube 1 was removed and added to tube with 99 mL saline (tube 2) dilution is 1/100.

transferred volume  into the plate is 1 mL.

Now, we have to determine the cfu/g Gram-negative bacteria in the fecal sample

Formula to calculate CFU/g bacteria in fecal sample is expressed as;

C = n/(s×d )

where C is concentration (CFU/g) , n is number of colonies , s is volume transferred to plate , d is dilution factor.

so we substitute

C = 30 / ((1/100) × 1)

C = 30 / 0.01

C = 3000

C = 3.0 × 10^3

THERFERE, the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3
