Why do all swordfish have ‘swords’? Use the word ‘inherited’ in your answer.

The swordfish bill, on the other hand, is smooth and horizontally flattened, better suited perhaps for whacking larger prey like squid. Beyond their "swords," all billfish come equipped with a remarkable internal heating system for their eyes, keeping them ten to fifteen degrees Celsius warmer than ambient water temperatures.

sorry if it didn't help but pls brainliest? :/

the cell theory states that all living things including animals, as well as plants, are made of cells.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
