Toadfish are fish that can produce croaking noises using muscles that contract
rapidly, called "sonic muscles". The figure above is plotting two parameters (force
and concentration of free calcium in the sarcoplasm) of three different types of
muscle cells in the toad fish (s-sonic muscle, w=white muscle, r=red muscle) during
the first 0.6 seconds (x axis is time in seconds).
From this graph you can conclude that
| sonic muscle cells contract more quickly than red muscle cells
sonic muscle cells contract more quickly than white muscle cells
sonic muscle cells relax more quickly than red muscle cells
sonic muscle cells relax more quickly than white muscle cells
white muscle cells contract more quickly than red muscle cells](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa2e3077d-cbc0-45f7-9f87-4f4dffd97b37%2F9a098ed5-7ef3-4ae2-b654-964026a89b2e%2F7zq08vt_processed.png&w=3840&q=75)
