SOLUTIONS (ANSWERS VERIFIED 100% CORRECT)
Paurometabolous metamorphosis - ✔✔gradual...egg>nymph>adult
-immature differs from adult
Hemimetabolous metamorphosis - ✔✔Incomplete, immature and adult differ
considerably
Holometabolous metamorphosis - ✔✔complete...egg>larva>nymph>adult
Diapause - ✔✔The arrest of development to enhance survival of insect generations
Instar - ✔✔developmental stage between molts until mature.
Molting - ✔✔The shedding of rigid exoskeleton to help insects grow
Nymph - ✔✔Immature form in hemimetabolous development
Larvae - ✔✔immature form in hemimetabolous development
Layers of integument - ✔✔epicuticle, exocuticle, endocuticle, subcuticular space,
basement membrane (epidermal cells)
Steps of molting - ✔✔Apolysis or separation of exoskeleton from epidermis> ecdysis
or shedding of epi and exocuticle> molting
, Scientific process - ✔✔Observation>hypothesis (prediction)> experimentation>
evaluation
Control - ✔✔important because you must have something to compare the
experimental group to so you know what the typical behavior of the controls
