Answer:
Explanation:
A)The exoskeleton provides a large surface area for the attachment of muscles and, in addition to functioning in support and movement, also provides protection from the external environment.
b) Appendages are variously modified among taxa for locomotion (walking, swimming), feeding, grooming, respiration, sensory reception, reproduction, and defense.
C)ORGAN OF RESPIRATION:-Aquatic arthropods respire with gills. Terrestrial forms rely on diffusion through tiny tubes called trachea. Trachea are cuticle-lined air ducts that branch throughout the body, and open in tiny holes called spiracles, located along the abdomen.
BALANCING ORGAN:-In arthropods,t he balancing organ is statocysts.
ORGAN OF EXCRETION:-Arthropods excrete by means of malphigian tubules, projections of the digestive tract that help conserve water. Terrestrial forms excrete nitrogen as uric acid, as do birds.
