Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules. The height to which capillary action will take water in a uniform circular tube (picture to right) is limited by surface tension and, of course, gravity.
Answer:
Climate Change: Atmospheric Carbon Dioxide. The global average atmospheric carbon dioxide in 2018 was 407.4 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. ... Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy.
Explanation:
la biodiversidad es importante porque aumenta la productividad para cada tipo de cosa, y ese es un papel importante en la naturaleza.
Im guessing it is due to gene shuffling
Answer:
b
Explanation:
The correct answer would be 6.4 x
cells/ul.
For 1 x 10-6 dilution, the plating factor is
. To find the number of bacteria in the original sample, the plating factor is multiplied by the colony count per ul.
<em>Number of viable bacteria = plating factor x colony count/ul</em>
Since 10 ul gives 64 colonies. 1 ul will give:
64/10 = 6.4 colonies.
Therefore, the viable bacteria in the original sample = 6.4 x
cells/ul
The correct option is b.
