Question

Many insects, including the giant dragonfly Meganeura, develop in water as larvae but metamorphose into a terrestrial adult. What would you predict about the changes (if any) in this animal’s body system from larvae to adult?

Question 31 options:

Excretory: ammonia --> uric acid

Respiratory: gills --> tracheae

The described changes in the excretory and respiratory would both occur

The described changes in all systems (excretory, respiratory, and circulatory) would occur

Circulatory: closed --> open

Excretory: ammonia --> uric acid

Respiratory: gills --> tracheae

The described changes in the excretory and respiratory would both occur

The described changes in all systems (excretory, respiratory, and circulatory) would occur

Circulatory: closed --> open

Explanation / Answer

The Correct is: The discribed changes in all systems (excretory, respiratory, and circulatory) would occur

When the larva survives in water, the mechanism for excretory, respiration, and circulation will be of aquatic habitat type. Larva grows there grows into nymph.

Nymph is an alien like structure and can remain inthe standing or serene water for upto 4 to 5 years.

when nymph is metamorrphoses into adult on land , it occurrs on the stem of trees and leaves its shell or exudes there.

Now the mechanism of respiration circulation and respiration becomes that of terrestrial type.
