Yes. In fact, the vast majority of all abortions occur as spontaneous abortions, in the first trimester. This occurs as a result of the body ridding itself of cells/embryos which are malformed.
No, a catalyst alone cannot make a nonspontaneous reaction occur spontaneously. A catalyst can only speed up the rate of a reaction by lowering the activation energy, but it cannot change the overall thermodynamics of the reaction. In order for a nonspontaneous reaction to occur spontaneously, the reaction must have a negative change in Gibbs free energy (G) value.
Since the world's population is concentrated in Asia, that is where most abortions occur (26 million yearly); nine million of these take place in China. But if you look at what country has most abortions percentage wise it's Russia with over 50% of pregnancies aborted.
Non-spontaneous processes require intervention or energy input to occur, while spontaneous processes occur on their own without needing external help. Spontaneous processes tend to move towards equilibrium, while non-spontaneous processes move away from equilibrium.
Tubes do not spontaneously regenerate, although the procedure is medically reversible.
Approximately 73 million abortions occur worldwide each year, which translates to about 200,000 abortions per day. This averages out to roughly 8,300 abortions every hour, or around 138 abortions every minute. Therefore, approximately 2.3 babies are aborted every second, which amounts to about 138 babies every 60 seconds.
excess bleeding may occur only after specific, predictable events (such as surgery, dental procedures, or injury), or occur spontaneously, with no known initiating event.
Spontaneous abortion is another word for miscarriage aka not induced and the risk is bigger in the first trimester.

what do you mean by "missed" abortions?
All races have abortions.
Yes, illegal aliens have abortions as well.
Dayglo Abortions was created in 1979.
