The large number of antibodies that can be produced in a single individual is a result of a single B cell: producing multiple un
wariber [46]

The answer is; producing a unique antibody from all other B cells by genomic rearrangement.


An isolated B cell produces monoclonal antibodies (also called Immunoglobulins). Different B cell types produce different types of antibodies (hence the serum of an animal has polyclonal antibodies). Memory B cells are developed when a particular infection is eradicated by the immune system. These B cells proliferate when the infection returns by producing the same antibodies that were effective against the foreign entity.

Answer:

  • <u>Medullary hormones</u>: the epineprhin and the norepineprhin. <u>Five different effects that these hormones produce are:</u> increase heart rate, produce cardiac muscle contraction, elevate blood preasure, increase breathing, dicrease digestive activity, increase metabolic rate.
  • <u>The most important mineralocorticoid secreted by the adrenal cortex: </u>aldosterone.
  • <u>Actions of the aldosterone: 1. </u>Conserves sodioum ions and water in kidneys. 2. Excrete potasium ions 3. Conserves H2O.

Explanation:

The epineprhin and norepineprhin are the most important medullary hormons. They are so important because of the functions that they have. They are responsable for the increase of heart rate and if it´s movement, along with digestive and metabolic activity.

Thanks to the aldosterone which is the most important secreted minaralocoricoid, kidneys conserve water and sodium and eliminate posatium.

Alenkinab [10]
The one advantage of using DNS assay to detect maltose production is the formation of a soluble and colored product compound. 
The reaction that occurs between maltose and DNS in the assay is a redox reaction (reduction and oxidation) such that maltose gets oxidized and becomes Maltonic Acid while the DNS gets reduced into reduced DNS. The  intensity of orange/brown /red color of reduced DNS is proportionately related to the amount of Maltose in the solution.
