The answer is Dilutions
Bacterial culture is one of the laboratory examination that could be used to determine if a specimen contain bacteria. But it will hard to count the colony if the bacteria count is too high.
That is why the specimen of the culture need to be diluted to reduce the bacteria count of the specimen, so the result will be easier to count. The unit used would be colony forming unit(CFU) per milliliter.
Answer:
Endosymbiosis of an oxygen-using scavenger bacterium in a larger host cell−the endosymbiont evolved into lysosomes.
Explanation:
The evolution of eukaryotic cells in all probability included: endosymbiosis of an oxygen-utilizing bacterium in a bigger host cell−the endosymbiont developed into mitochondria. development of an endomembrane framework and consequent advancement of mitochondria from a segment of the Golgi. endosymbiosis of an oxygen-utilizing photosynthetic bacterium in a bigger host cell−the endosymbiont advanced into mitochondria. endosymbiosis of an oxygen-utilizing scrounger bacterium in a bigger host cell−the endosymbiont developed into lysosomes.
The crabs are salt water organisms, so they'll have a higher concentration gradient than the distilled water. In other words, they're hypertonic to the distilled water. This will cause them to take on water and expand; their cells bursting.
The layer is the Mucosa layer.
