Why could cancer cells want to absorb dna? would it simply them grow?

Steal energy from neighbouring cells. Cancer cells require extra energy throughout the growth process, and so change their energy consumption compared with healthy cells. When their healthy neighbours break down proteins into amino acid building blocks, the cancer cells absorb these and use them to grow.

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers
