<span>After ovulation, an oocyte, or egg cell, remains viable in the female body for up to 24 hours. The generally accepted lifespan in a woman's body is 12 to 24 hours for the egg and up to five days for the sperm cells. Intercourse occurring as many as five days prior to ovulation, therefore, could potentially result in pregnancy.</span>
The law of conservation mass states that <span>the atoms of an object cannot be created or destroyed, but can be moved around and be changed into different particles. So the only answer that makes sense is the first one: Matter can be changed but not created or destroyed.
Hope this helps!</span>

I'm not sure how exactly you wanted this question to be answered. You're either talking about the symmetry where animals would have two legs or two arms for example and thus producing a pair of each muscle on both sides of the body, or you're refering to the development of agonistic and antaonistic muscles where each of them served a different purpose; either extending or contracting.
