The ________ plate count (SPC) method involves diluting 1.0m of bacterial culture into a series of water blanks, and then taking
Anna11 [10]

The standard plate count (SPC) method involves diluting 1.0m of bacterial culture into a series of water blanks, and then taking a sample from the water blanks to add to empty petri plates which will be filled with melted agar.

The standard plate count is a method used in microbiology, which is used to gain an insight to estimate the density of bacterial population which is present in a bacterial culture broth. This is done by plating a small concentration of the culture in a petri-dish and then counting the colonies which form in the petri-plate. This method is used mostly in the food industry, to find the density of mesophilic bacteria in food. This method is extremely essential to determine the primary source of the bacterial contaminant.

why is important to use an organism with a recessive phenotype in a cross with an organism of unknown Genotype
bogdanovich [222]

Answer:

One of the central conclusions Mendel reached after studying and breeding multiple generations of pea plants was the idea that "[you cannot] draw from the external resemblances [any] conclusions as to [the plants'] internal nature." Today, scientists use the word "phenotype" to refer to what Mendel termed an organism's "external resemblance," and the word "genotype" to refer to what Mendel termed an organism's "internal nature." Thus, to restate Mendel's conclusion in modern terms, an organism's genotype cannot be inferred by simply observing its phenotype. Indeed, Mendel's experiments revealed that phenotypes could be hidden in one generation, only to reemerge in subsequent generations. Mendel thus wondered how organisms preserved the "elementen" (or hereditary material) associated with these traits in the intervening generation, when the traits were hidden from view.

Sequencing eukaryotic genomes is more difficult than sequencing genomes of bacteria or archaea because of the _____.
AlekseyPX
Are there options? because there are lots of answers. 

Firstly, eukaryotic DNA tends to be much longer; it's held inside a nucleus, so it has to be separated from the rest of the cell; and there are also mitochondria in most eukaryotic cells, which have their own RNA, which has to be separated.
