The correct answer is B. The Kuiper Belt is home to a dwarf planet similar to Pluto
Explanation
The Kuiper Belt is the most remote area of the solar system, it is an elliptical region, which is more or less 149.5 million kilometers from the sun. Its name refers to the fact that it is a belt, so it could be associated with the appearance of the asteroid belt that is located between Mars and Jupiter. However, in the Kuiper Belt most objects are icy rather than rocky. In this region of the solar system you can find several dwarf planets such as Pluto, these planets are classified as such because their size is enough to be considered as or asteroids, but they cannot be considered planets either because they do not meet any requirement. According to the above, the correct answer is B. The Kuiper Belt is home to a dwarf planet similar to Pluto
Answer: Slow, long lasting, widespread responses
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
