What is cellular respiration? A the process that our cells use to convert sugar
(glucose) into energy (ATP)

B the process that our cells use to break food down into smaller molecules (sugars)

C any process that makes acid

D the process of breathing

D is the answer for the question

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
