Answer:
Promoter 2
Explanation:
Promoter 2 is the best choice because the resistance gene will only be expressed in the leaves of the corn plant. Promoter 3 only expresses genes in the corn roots, so the toxin would not be available in the leaves for the pest to eat. Promoters 1 and 4 would express the resistance gene in the leaves of the corn plant, but the toxins would be expressed in the corn cobs as well, which may then be fed to livestock.

Octopus and squid have little suction cups on their tentacles. It helps with sticking onto food (so it doesn't get away) and also helps with sticking into things. If it wanted to camouflage into some rocks, it can use its tentacles to cling to to the rock.
Tentacles can also grab and carry things. Scientists have made tests where they would put a clam in a jar with the lid screwed on. The octopus would grab onto the jar and use its tentacles to twist the lid off.
Without tentacles, octopuses and squids would be pretty helpless and probably couldn't survive in the deep ocean.
