Which statement correctly distinguishes between all mechanical and all electromagnetic waves? electromagnetic waves carry energy perpendicular to wave motion; mechanical waves carry energy parallel to wave motion. mechanical waves carry energy perpendicular to wave motion; electromagnetic waves carry energy parallel to wave motion. electromagnetic waves carry energy through a medium; mechanical waves carry energy through media and space. mechanical waves carry energy through a medium; electromagnetic waves carry energy through media and space.

Mechanical waves carry energy through a medium; electromagnetic waves carry energy through media and space.

Explanation:

The waves which require medium to travel are known as mechanical waves. The waves carry energy forward by compression and rarefaction that is by changing density /pressure of medium particles.

Electromagnetic waves can transfer energy through space as well as medium. In an electromagnetic wave, electric field generates magnetic field and magnetic field generates electric field. Electric field and magnetic field are perpendicular to each other and to the direction of motion.

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
