A debate is where you talk with your peers about ideas and you sometimes argue about what is right or what should be done. but its nothing to be worried about. you can let the others argue, but you can listen and then talk. thats the best thing to do, to listen, then speak.
good luck!
Answer:
difference:
1. The generation mechanism is different, the mechanical wave is generated by mechanical vibration; the electromagnetic wave generation mechanism is also different, there is the periodic movement of electrons (radio waves); the outer electrons with atoms are generated after being excited (infrared, visible, ultraviolet) The inner electrons with atoms are generated after excitation (roentgen rays); the nuclei with atoms are generated after excitation (gamma rays).
2. The propagation mechanism is different: the mechanical interaction between the particles and the alternating induction of the electromagnetic field.
3. Mechanical waves have both transverse waves and longitudinal waves; electromagnetic waves are material waves and belong to transverse waves.
4. The influence of the medium on the propagation speed is different

The answer is d because i had the same problem yesterday in biology
Answer:
Instead of a brain, echinoderms have a ring of nerves located around their mouth area that governs their nervous responses. This ring coordinates their motion, their eating, basically anything that requires nerve control.
