Explanation:
Earth's Orbit = 2*pi*R = 942,000,000 kilometers.
Distance/Time = 942,000,000 km / 8766 hr = 107,000 km/hr = 30 km/sec.
I think the correct answer from the choices listed above is option A. Both insects and roundworms exhibit molting during growth, whereas sponges, snails, and leeches do not. It is the process of shedding old feathers, hair or skin to make way for new growth.

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."
