The correct answer is "an open circulatory system".
Explanation:
Larvae that have exoskeleton, system of tubes for gas exchange, and modified segmentation lead to the formation of adult insects that have an open circulatory system. The system of tubes for gas exchange of the larva are modified once metamorphosis occurs, forming air-filled tubes called tracheae that serves to the adult insect to perform respiration within an open circulatory system.
<u>Option -</u> An open circulatory system inside the adults.

Most of the invertebrates like the insecticides have the open circulatory system, as the system has no specific pathways for the transportation of the materials and other essential nutrients through the medium but they have a more different mechanism in order to provide the sufficient materials to survive.
the scientist has determined that the chemical isolated from charcoal-grilled meat is an oxidant.
Explanation:
oxidants are oxidizing agents. oxidants have the capacity to damaging living cells. vitamin C on the other hand is an active antioxidant, hence it was able the breakdown of the cells.
Student 1’s methods would be more accurate, because the student would control more factors. Only one variable at a time (either temperature or acidity) would be tested on each group of worms. On the other hand, Student 2 is testing both factors on all the worms, which could make the results unclear.
