Modelling refers to using a diagrammatic representation to present a particular event or biological activity.
The two maps shown are very good for representing/modelling mitosis.
Advantages
- They clearly lists the various steps involved in mitosis and as well included the process of cell division starting from the interphase stage (for the second diagram).
- The M phase was also clearly explained in the first diagram.
Disadvantages
- The first pictorial diagram had to labelling to depict the name of each particular phase and makes understanding difficult.
- The second diagram fails to show pictorial representation of what could have exactly happened in each stage in the process of cell division.

Answer:
It help to decode the act of bacteria in converting organic nitrogen into ammonia. It decode the activities of microorganisms in the conversation of organic nitrogen to ammonia
Explanation:
Ammonification is the process whereby microorganisms help to convert organic nitrogen into ammonia.
The correct answer is the mouth. Digestion begins when food enters the mouth, chewed, and mixed with saliva. Food usually has complex carbohydrates such as starch in them and saliva has an enzyme called salivary amylase which can break down these complex carbohydrates into simpler molecules (i.e. dextrins). After which, these dextrins are digested further in the stomach and in the small intestine by the action of enzymes such as the pancreatic amylase which further breaks down dextrins into oligosaccharides and disaccharides. Other enzymes such as trypsin breaks down proteins into amino acids and lipase that breaks down fat into triglycerides. In the brush border of the small intestine, there are enzymes such as oligosaccharidases and disaccharidases which breaks down sugars into their most basic forms (i.e. glucose, fructose, galactose) which can be readily absorbed in the intestine. Amino acids and tricglycerides are also readilty absorbed in the intestines with the latter by the help of emulsification by bile.
The answer is D. When prevention methods are necessary.
