Specimens taken from a patient sample usually contain a mixture of different bacteria. But sample with only one type of bacteria, are necessary to study a bacterial species accurately. Therefore, it is necessary to isolate all of the possible disease causing organisms in order to study the sample by itself. Once isolation of individual colonies is done, then these colonies can be used for identification tests. A sample of the specimen is move very fast onto an agar plate in order to physically separate the bacterial colonies.

Therefore, the question states an example of a run-out sentence.
35 parts per thousand
Sea water. Seawater is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of approximately 3.5%, or 35 parts per thousand. This means that for every 1 litre (1000 mL) of seawater there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it.
