Answer:
The correct answer will be- nasal septum
Explanation:
The nasal cavity is the hollow space or cavity connected to the two nostrils which allow the inhalation and exhalation of the air into the nose.
The nasal cavity is divided into left and right portion by a cartilaginous bony structure called nasal septum. The nasal septum lies in the central position and divides the nasal cavity into symmetrical portions.
Thus, the nasal septum is the correct answer.
The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism. Later, when pollution was reduced, the light-coloured form again predominated. Industrial melanism in the peppered moth was an early test of Charles Darwin's natural selection in action, and remains as a classic example in the teaching of evolution. Sewall Wright described it as "the clearest case in which a conspicuous evolutionary process has actually been observed."
