It's a way of producing offspring and to pass one's genes on to the next generation. Cows don't live forever (nor do any animal on this planet), so it's crucial to mate to have other offspring pass on their genes to the next generation.
Yes.

Cows can breed for as long as they are productive, which can range from one to 15 years or more.

Cows (and heifers) can only attract a bull as a mate if they go into heat. They give off pheromones from their systems and through their urine, as well as beller a lot, pace around a lot, mount other cows, pick fights with other cows, and even do a bit of foreplay with the bull. When push comes to shove then the mating begins.
