1)The approximate length of a adult rat’s small intestine can reach 80 centimeters long.
2)The small intestine
is so large compared with other organs because it is where most digestion (macromolecules of food are
broken down into nutrients) and absorption of nutrients occur. With more area of surface in the organ the more
digestion can occur.
3) Caecum is a part of the colon that contains a lot of bacteria that aid in digestion of plant material. In rats the cecum is larger than human's becausethey eat more seeds and grains.
This lead us to believe that rats are more herbivores than carnivores.
4) function of colon: Colon extracts water and electrolytes from solid wastes before they are eliminated. It's also where bacteria ferment unabsorbed material occurs and from that they can produce vitamins important for our body, such Vitamin K.
5) if the cecum is large it means the rat is herbivore because they host a lot of bacteria, which aid in the enzymatic breakdown of cellulose; If the cecum is small the rat is carnivore, since their diets contain little or none of plant material and the cecum is often partially or wholly replaced by the appendix.
The fossilized fish which is found has jaws but no true bones belonging at point B on the Cladogram. Thus, the correct option is B.
<h3>What is Cladogram?</h3>
A cladogram may be defined as a phylogenetic tree that is based on the classification of evolutionary relationships.
In the given cladogram, D is any ancestral point from which speciation occurs. Point C is a basal taxon while A and B are sister taxons.
The organisms of point B have only jaws bu,t not true bones, while the organisms at point A have both jaws and true bones.
Therefore, it is well described above.
