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.

Answer:
The correct answer is D: "<em>Apes have a Y-5 pattern of cusps, whereas Old World monkeys have a bilophodont pattern</em>".
Explanation:
Apes and old world monkeys only have four kinds of teeth: <em>two incisors, one canine, two premolars, and three molars</em>. This dental formula is 2.1.2.3.
The old world monkeys characterize for having molars with four cusps joined by ridges. They have bilophodont teeth with better crushing, shearing and wearing capabilities than apes.
Apes´molars have 5 cusps, a Y-shaped space between those raised points, and no transverse lophs. These characteristics are known as the Y-5 pattern.
