By definition, the phenotype is the actual physical manifestation of an organism's genotype, so the way an organism looks or behaves is what is being selected on. For example, if ladybugs have red (R) shells or yellow (r) shells and ladybug-eating birds only eat the ones with red shells, any red-shelled ladybugs will be selected against based only on their phenotype. The birds do not know whether each bug is RR, Rr, of rr, so phenotype, not genotype, is what is affected by natural selection.
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:
There are 8 electrons in the outer ring, and has to react with 8 or fewer electrons to form a stable molecule.
Explanation:
The outer-most orbits of silicon contains a maximum of eight (8) electrons. It requires 8 of fewer electrons to form a stable molecule.
