A scientific theory is an explanation for a naturally occurring event that has been developed by extensive observation, experimentation, and reasoning. Often a theory integrates the information accumulated by many different scientific disciplines. As new information is discovered theories may be modified, but they are rarely discarded. The theory of continental drift was proposed by Alfred Wegener, a German scientist, in 1915. He believed that the continents had once been joined together as one supercontinent, which he named Pangea. What evidence did Wegener use to support his theory?

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
