An entomologist is researching spruce moth traps. She is interested in two factors: 1. type of lure in the trap (scent, sugar, chemical) and 2. location of trap (top branches, middle branches, lower branches, and ground). She want to know how these factors impact the number of spruce months found in the trap after 48 hours. What is the best description of "Lure: scent and Location: ground"?

b. to discover aspects of the natural world.

yes, because even though a theory has a  lot of evidence to support it, it is not always true

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
