The lophophore is used in Reproduction Excretion Feeding Growth A trochophore is A feeding structure found in some animals A larval stage found in some animals A chemosensory structure found in some animals A type of flatworm True (A) or False (B): Lophotrochozoans all share similar morphological characteristics True (A) of False(B): Bryozoans are colonial animals The wheel-like structure on a rotifer's head is the Corona Mastax Pharynx lophophore An intermediate host Is where a parasite's adult stages reproduce sexually Is where a parasite's larval stages reproduce asexually Annelids have A segmented body A true coelom Bristles called chaetae All of the above The shell of a mollusc is secreted by the Visceral Mass Foot Mantle Head Estuaries Contain only marine water Contain only fresh water Contain a mixture of both marine and fresh water If an organism maintains the same internal ion concentration while the salinity of its environment is changing around it, it is a Osmoregulator Osmoconformer We will use a to measure salinity in our lab activity Barometer Refractometer Spectrophotometer Salinometer

Explanation / Answer

55. C. Feeding.

Lophophore is the circular or horseshoe-shaped feeding organ composed of ciliated tentacles surrounding the mouthuman in some invertebrates like brachiopoda and bryozoans.

56. a larval stage found in some animals.

Trochophores exist as a larval form within the trochozoan clade, which include the entoprocts, molluscs, annelids, echiurans, sipunculans and nemerteans.

57. False.

58. True.

59. A. Coronary

The most distinctive feature of rotifers is the presence of a ciliated structure, called the corona, on the head.

60.b. is where parasites larval stage reproduces a sexually.
