Answer:
The correct answer to the question above is "PLATE COUNT TECHNIQUE"
Explanation:
DIRECT MICROSCOPIC OBSERVATION is the method of estimating the number of microorganism using microscope. Samples to be estimated are placed on microscope slides which allow few cells in a small volume to be counted. Then, the value determined is used to estimate the total number of cells mathematically. It is only difficult to aee small cells which may affect precision.
VIABLE COUNT is the estimation of the living cells in a given sample.
PLATE COUNT TECHNIQUE is used to estimate the number of viable cells that are present in a given sample of actively growing or dividing cells based on bacteria cells found on agar plate. A sample to be counted is diluted in a solution that will not kill the microorganisms, this is done to enable accurate counting as only living bacteria will be counted.
The structure is calcium ions.
Infiltration is the downward movement of water into the soil and runoff is when water flows above the surface of the soil
Answer:
The answer is class and family.
Explanation:
Taxonomic groups are used for biological classification. There are eight main taxonomic groups: domain, kingdom, phylum, class, order, family, genus and species, with the domain as the most inclusive and species as the least inclusive. If we take a look on Mammalia and Hominidae classification, we can assume that Mammalia represents class, and Hominidae represents family:
1. Domain: Eukarya
2. Kingdom: Animalia
3. Phylum: Chordata
4. Class: Mammalia
5. Order: Primates
6. Family: Hominidae
7. Genus: Homo
8. Species: Homo sapiens
