Question

Select the correctly matched organism with their Excretory and Respiratory structures respectively,
1) Limulus Coxal glands and Trachea
2) Periplaneta Trachea and Malpighian tubules
3) Pila Keber's organ and Book gills
4)Balanoglossus - Proboscis gland and pharyngeal gills​

Answer 1

Answer:

limulus have book gills so it's wrong

2 is wrong (trachea is for respiration and MT is for excretion )

3) pila's respiratory organ is CTNIDIA so it's wrong

4) IS correct

Answer 2

Correct answer: option 4

Balanoglossus - Proboscis gland and pharyngeal gills​.

• 1) Limulus also called horseshoe crabs has a series of book gills(    gills arranged in membraneous folds)on either side of the body.

• Coaxial glands are found in some arthropods for collecting and excreting urine.

• The trachea is the long tube that connects your larynx(voice box)to your bronchi which sends air to your lungs.

• These 3 won't match. So option 1 is wrong.

• 2)Periplaneta will come under the class Insecta of phylum Arthropoda. American cockroaches (large cockroaches) will come under this group.

• The trachea as discussed above is associated with humans.

• Malpighian tubules are a kind of excretory and osmoregulatory system found in some insects.

• These three also won't match. So option 2 is also wrong.

• 3) Pila Keber's organ is an excretory organ present in pilaBookgills are gills found in Limulus.

• These 2 also won't match.

• So option 3 is also wrong.

• 4)Balanoglossus is a sluggish animal and the most active part of their body is the proboscis. Burrowing is exclusively done by proboscis. They respire through pharyngeal gills.

• So option 4 is correct..
