Octopuses, or octopi, are predators. They hunt crabs, prawn, fish, and mollusks. However, in turn they are also hunted by sharks, dolphins, and other sea animals, so they are also prey.
They start off as uncoloured fry and as they grow and develop, their colours also develop until they are fully coloured.
That depends on its application in science or geometry which has not been given. In science it can turn light into different colours and in geometry it can be in the form of a triangular prism.
it depends on what is in the alkali, sodium, calcium, lithium all turn different colours, I believe lithium turns purple, an alkali is a compound with hydroxide ie sodium hydroxide is NaOH
