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.

How does the anatomy of a female rat differ from that of a human?
gulaghasi [49]
A difference between female rats and humans is that a rat's vagina connects to the urogenital aperture and humans do not have a urogenital aperture. The vagina is a short, muscular canal located below the urethra. Additionally, the rat's vagina is much shorter in length than the human vagina. In female rats, the ovaries which produces egg cells and female hormones, are small and located just below the kidneys inside the peritoneal membrane. Also the shape of the uterus in rats is different than in humans. In rats it is Y-shaped and in humans it's a pear shaped organ.

Tema [17]
Black squirrels may increase in a certain area due to natural selection because of the ground below it being dark so the squirrels would adapt to the terrain, making them harder to see by predators.
EXAMPLE: if a light fur colored squirrel is on a dark terrain, an Owl or Large bird could easily see the color differentiation and notice that it is a small land organism (prey).
So the squirrels kin would evolve in the sense that they would have darker fur to match their inhabitance

Identify the types of point mutations depicted. Glycine (G G C) is transformed to Glycine (G G A). Glycine Glycine missense muta
Charra [1.4K]

A single change or alteration in the nucleotide base of the genetic material of the cell is called a point mutation.  It can be a deletion, addition or inversion of a single nucleotide base.

In the following, the mutations that occurred are 1. C and 2. B.

<h3>How the mutation can be explained?</h3>

  • <u>Silent mutation</u> occurs in a single base of the triplet codons of the bases but the alterations do not cause an observable effect and they remain as a neutral alteration. They do not affect the function of the protein. Thus, the glycine to glycine is a silent mutation.

  • <u>Non-sense mutations</u> are caused when the single change in the nucleotide base results in the formation of the stop codon. Thus, lysine to stop codon is a nonsense mutation.

Therefore, silent and nonsense mutations are the correct options.
