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.

Answer:
Bacteria do not possess the tendency to withdraw sequences of introns from a gene, thus, if the gene for the human growth hormone were transcribed, it would translate into a non-functional protein.
When the expression of a gene takes place in eukaryotes, the budding mRNA comprising introns are removed consequently at the time of post-translational processing to produce mature mRNA. Also, the human growth hormone is produced by the pituitary gland in the form of a pre-hormone comprising a leader peptide of about 20 amino acids in length, which need to get removed post-translationally to produce a mature functional protein.
Bacteria do not possess the biochemical machinery either to effectively withdraw the leader peptide after translation or to splice out the introns. Thus, when an unchanged human growth hormone is cloned, the bacteria cannot produce the functional human growth hormone.
The cause of the client’s pain must be because of atrophy of
bulbouretheral glands. The bulbourethral glands are the one responsible for
secreting a substance which we call alakaline, in order to be able to provide
neutralization in the acidic environment in a person’s urethra. The
bulbourethral glands are also responsible in having to provide lubrication to a
person when having to do a sexual intercourse. If it gradually declines in its
effectiveness, during sexual intercourse, it would likely cause the person to have
pain and have difficulty in having to do an intimacy with the person’s partner
as atrophy may be present in the person’s bulbourethral gland.
Explanation:
The wings of owls and quails are similar because they are homologous structures made of same pentdactyle pattern. The wings in both made of the same bone pattern and structure. The wings function is a bit different in both as they live in different habitats. The homologous structures indicate divergent evolution.
