Explanation:
<span>Sympathetic nervous system accelerates the heart rate, decrease movement of the large intestine, and perspiration. The sympathetic pathway is arranged in sequence which is: craniosacral origin, short preganglionic fiber, ACh release at ganglion, long postganglionic fiber, ACh release at effector. The identical pathways of the axon in sympathetic preganglionic are ventral root, spinal nerve, ramus commucans, and sympathetic trunk.</span>
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.
