The organ of the rat that serves the same function is the cecum
Rats are strictly herbivores and therefore do not get much animal fat and the gall bladder is not necessary. The cecum is a large, thin-walled, blind pouch shaped looks like a comma, highly constricted at the middle, the rat cecum is different from others rodents as it is devoid of internal septa.

Given: The population density of frogs in a portion of a pond is 12 frogs per square meter. The size of the entire pond is 370 square meters.
To find: The total population size of the frogs in the pond.
Method: Using unitary method of proportions
Solution:
Let p be the density of the frogs present per square meter.
Let A denote the total area of the pond.
∴ p = 12 frogs/m² and A = 370 m²
The total number of frogs in the pond is given by,
Therefore, there are 4440 frogs in the pond.
