Which of the following is an unsegmented animal with a free-swimming larval stage? A. flatworm. B. annelid. C. mollusk. D. echinoderm

Answers

Answer 1

Answer: The answer is C. mollusk.

Among the all choices, echinoderm and annelid are segmented animals. So, it leaves flatworm and mollusk as possible answer. However, flatworms have no a free-swimming larval stage. Mollusk is an unsegmented animal with a free-swimming larval stage we were looking for. After eggs production, from them trochophore larvae can emerge. This trochophore larvae is planctonic which means it is a free-swimming.

During a(n) _______________ change, a system absorbs energy from its surroundings.

Answers

Answer: Endothermic

Explanation:

An endothermic reaction occurs when energy is absorbed as heat, while a reaction is exothermic when heat is released. Thereby, these type of reactions require external energy to proceed and heat is the reactant.

So, an endothermic reaction absorbs heat from the surrounding environment and stores that energy in the bonds of a new molecule formed, and this results in a decrease in temperature.

Enthalpy usually increases in endothermic reactions. However, a spontaneous endothermic reaction can occur if changes in entropy and enthalpy yield a negative Gibbs free energy.

endothermic (I have to fill in 20 characters so please ignore the parentheses)
