Answer:
b. Vitamin K deficiency inhibits the blood’s ability to clot.
Explanation:
The main form is vitamin K1 (phylloquinone); followed by vitamin K2 (menaquinone), formed from the bacterial action on the large intestine tract and a third compound, vitamin K3 (menadione), a synthetic fat-soluble molecule. These vitamins can be found in many foods: in green vegetables (lettuce, cauliflower and spinach), in tomatoes, Brazil nuts, cashews, potatoes, contained in soybean oil, egg yolk, milk and to a lesser extent in wheat and oats.
Vitamin K participates in blood clotting, its deficiency can make it difficult to stop bleeding. Also causing damage to the body when in excessive concentration, for example: dyspnea (shortness of breath), and chest pain in adults with high vitamin K1 disorder and hyperbilirubinemia in newborns whose mothers in gestation underwent treatment with based on vitamin K3.

I believe that the most common antibody switch is from IgM to IgG.
Class switching occurs by a mechanism called the class switch recombination binding. It is a biological mechanism that allows the class of antibody produced by an activated B cell to change during a process known as isotype or class switching. The mechanism changes a B cell's production of antibodies from one form to another, such as from the isotype IgM to the isotype IgG.

The chromosomes are separated by a structure called the mitotic spindle.
A chromosome is a lengthy DNA molecule with component or all of the genetic material of an organism. In maximum chromosomes the very lengthy skinny DNA fibers are lined with packaging proteins; in eukaryotic cells the maximum vital of those proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to keep its integrity. These chromosomes show a complicated third-dimensional structure, which performs a large position in transcriptional regulation.
Chromosomes are generally seen below a mild microscope best for the duration of the metaphase of molecular division.
