Read the scenario. Olivia is entering a competition to build a device that automatically feeds
fish every day. She has built a prototype and done multiple rounds of
testing and improvement. She thinks her design and the prototype are
where they should be.
Which option describes what Olivia is MOST likely to do next?
Select one:
Identify the criteria and constraints of her design,
Study existing automated fish feeders and compare her design to them.
Communicate her design and prototype to others.
Build a prototype of another design idea in order to compare the two,

not: both offer magnification to the atomic level.

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.
