They are oxygen, carbon, hydrogen, and nitrogen.
Organic molecules, which are found mostly in food. These molecules have C-C or C-H bonds, which are high energy bonds.
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
• The kingdom PROTISTA includes autotrophic and heterotrophic, unicellular and multicellular organisms.
• The most specific taxonomic level is SPECIES
• The characteristic of all living things is PRODUCE OFFSPRING BY MEANS OF SEXUAL REPRODUCTION
