Answer: b. Muscles
A metazoa is a division of animal kingdom that includes all animals expect protozoa and sponges. Metazoa division includes multicelluar animals, which exhibit highly differentiated cells. They have muscular and nerve system and well coordinated tissues and organs. Locomotion requires a coordination activity of muscular, skeletal and neural system. It is mainly achieved by contraction and relaxation of muscles that occurs due to specialized muscle proteins named as actin and myosin which receives signals from nerves.
Hence, locomotion in metazoa is due to contraction of muscles.
The CPT code that will be reported for moderate sedation is 9914 [4].
This is the government approved CPT code for moderate sedation for patients that are five years old and older and the code is used when the moderate sedation and the other needed procedure is performed by the same health provider for the intraservice period of 15 to 30 minutes.
This is a physics question, not biology, but...
f=1/T where f is frequency and T is the period.
f= 1/(1/3)=3
frequency =3 Hz
The independent variable would be the color of light, the dependent variable would be the growing speed, the control variable would be colorless light
