Ionic bonds have relatively high melting and boiling points, compared to that of covalent bonds.
Ionic compounds have strong electrostatic bonds between oppositely charged ions. Covalent bonds, on the other hand, have weaker attractions between molecules.
Remember, the melting point, is simply the amount of heat (energy) it takes to break apart the molecular bonds. The stronger the bonds, the harder it will be to separate them!
Hope this helps! :)

I thought I already answered this but anyways, the answer is A. Zebras will live and graze in herds. When a predator spooks the herd the zebras run as one. That ways it confuses let's say the lion because they see in black and white. To them they see racing stripes so it's hard for them to decide which zebra to take down. If running together backfires, the zebras will stand their ground and protect the weaker and younger zebras by kicking and biting the lions. Hope this helps!
During the Proterozoic life evolved from simple bacteria having prokaryote cells, first to more complex single celled organisms, the eukaryotes, and then to multi-celled plants and animals. It is also during this time that the earth's atmosphere was transformed by cyanobacteria.
