Galapagos tortoises have specific modifications that allow them to consume food and survive on the galapagos islands. arrange the steps of the evolution of galapagos tortoises in the correct order. 1.the shrubs were high off the ground and out of reach for the tortoises. 2.this motion gave their shells a saddle-like appearance. 3.the tortoises fed by craning their necks upward. 4.over time, turtles with arched shells and longer necks were more likely to survive. 4.tortoises swam from the mainland to the galapagos islands. 5.they settled in the ecosystem available there.

The correct arrangement of events in evolution of tortoise is:

The steps of the evolution are in first the cause of change or the first step in new environment.

Then potential difficulties faced by the new specie.

After that description of the body changes to minimize the effect of change in environment.

At the end adaptions.

So according to above plan correct arrangement of evolution of tortoise is given in answer.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
