Verified Correct Answer: Option D
Chemical Principles & Mechanism
The formula for the heat of reaction (\DeltaH) in an energy profile for an exothermic reaction is \DeltaH = H\(_{products}\) - H\(_{reactants}\). In an exothermic reaction, the products have a lower enthalpy than the reactants, resulting in a negative \DeltaH value, indicating heat is released.
In the energy profile, \DeltaH = H\(_{products}\) - H\(_{reactants}\) is represented by the part labelled IV

The following organisms are hermaphrodites EXCEPT?
A
snail
B
Taenia
C
Schistosoma

Earth worm
medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
most land snails are pulmonates and are hermaphrodites.
Unlike all other trematodes, schistosomes are not hermaphroditic but dioecious, forming separate sexes.
Adult worms have elongate tubular bodies, each male having a unique gynecophoral canal (schisto-soma = split body) in which a female worm resides.
