<span>It's because the process is not as organized as we have learned it. We tend to think of intracellular reactions as they're supposed to work. Only thymine is supposed to bond to adenine. Only a specific type of ligand bonds to a certain receptor etc. this type of thinking leaves it hard to imagine what's actually going on. Imagine complete and utter chaos. Enzyme being hit by all the wrong and right molecules many many times per second. Molecules flying off in every which direction and hitting against anything and everything. When we learn about these reactions we tend to think it's ordered based on how specific things are. Not only is an enzyme/protein site made to fit only a specific molecule, it has to be the correct orientation. So even if the right molecules are in the right place hitting against the right enzyme does not mean it will attach, assuming it doesn't approach at the right angle.</span>

Cervix
Janine recently had surgery on the neck, or narrow lower portion, of her uterus. Janine's surgery was performed on the cervix.
The cervix is the narrow neck-like passage that forms the lower portion of the uterus in the human female reproductive system. The cervix joins the vagina and uterus and it is mainly made up of fibromuscular tissue. The two major parts of the cervix are ectocervix and endocervix. During menstrual cycle, the cervix opens a bit to allow the passage of menstrual flow. The cervix also dilates largely to allow the passage of baby during childbirth.
Answer:
The scream-y howl is most often heard during the breeding season, in the springtime. It is...horrible. A shrill, hoarse scream of anguish, it sounds more than anything like a human baby undergoing some kind of physical torture. It's thought that this call is used by vixens (female foxes) to lure male foxes to them for mating, though males have been found to make this sound occasionally as well.
