Many small or simple creatures have no heart. If you are made of only one or a very few cells you have no need of a circulation system because substances can travel sufficiently fast by diffusion. A jellyfish is an example.
YES because pretty much any animal can have a heart attack.
No, all hearts are the same, just a muscle.
As in ANY living animal, its brain, then heart and lungs or gills.
No, they are sponges. Actually they are the only animal phyla that does not have any "true tissues".
It can beat at any rate...it depends what time of animal you are talking about, humming birds would have a much faster heartbeat versus an elephants' would be slower ;)

Yes. Just like any other animal that has a heart, the function of a frogs heart is to pump blood to all of its body's tissues.
pretty much the same as any animal with the heart veins arteries and capillaries
