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.

Can Mutations can spontaneously occur during DNA replication?
Yes
A synthesis reaction will occur spontaneously if heat of formation of product is?
large and negative
Chemical reactions that energy often occur spontaneously?
endothermic: or energy absorbing reactions
Can tubal ligation regeneration occur?
Tubes do not spontaneously regenerate, although the procedure is medically reversible.
Where are abortions most common?
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.
When does excess bleeding occur with hemophilia?
excess bleeding may occur only after specific, predictable events (such as surgery, dental procedures, or injury), or occur spontaneously, with no known initiating event.
Describe the role of energy in chemical reactions?
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without energy.
When do spontaneous abortions usually occur?
Spontaneous abortion is another word for miscarriage aka not induced and the risk is bigger in the first trimester.
Although genetic mutations may occur spontaneously in organisms the incidence of such mutations may be increased by?
Radioactive substances in the environment
What are considered Favorable chemical reactions?
Chemical reactions that occur spontaneously usually give off energy, usually heat.
Why does a keloid occur?
Keloids are benign (noncancerous), fibrous skin tumours. Keloids usually occur at the site of skin damage (acne, burns, chicken pox, cuts, insect bites, piercings, surgery, tattoos, vaccinations), although they can occur spontaneously.
What is the difference between a reaction that happens spontaneously and a reaction that doesn't?
The difference can be clarified by entropy (the second rule of thermodynamics).The reaction is more spontaneous with higher entropy, for the reactions that occur spontaneously the entropy is higher than for the ones that do not.
