Question

ciliary rosettes found in the animal​

Answer 1

Answer:

A rosette is a rose-like marking or formation found on the fur and skin of some animals, particularly cats.Rosettes are used to camouflage the animal, either as a defense mechanism or as a stalking tool. Predators use their rosettes to simulate the different shifting of shadows and shade, helping the animals to remain hidden from their prey.

Answer 2

Answer:

• The same worm has both male and female reproductive organs. The earthworms are hence referred to as hermaphrodites.
• Self-fertilization is prevented because the development of the sperm occurs before that of the ova. It is referred to as protandry.
• Two pairs of testes and two vasa deferens make up the male sex organs. Segments 10 and 11 contain testes.
• The anterior septa of segments 10 and 11 are covered in tufts of finger-like structures.
• Seminal versicles are two pairs that develop from the testicular segments. The testes are located in the same segment as two pairs of seminal funnels known as ciliary rosettes.
• A lengthy tube known as the vas deferens connects the ciliated funnels on the same side. Up until the 18th segment, where they open to the exterior through the male genital aperture, the two vasa deferens of both sides run backwards along the ventral body wall. Penial setae for copulation are present in the male genital openings.
