vascular layer

Explanation:

The wall of the eyeball is made up of three layers which are a fibrous tunic, vascular tunic, and retina, also known as an inner tunic. The middle layer of the eyeball is the vascular tunic or uvea which in turn is composed of three parts: choroid, ciliary body, and iris.

Choroid becomes the ciliary body in the anterior portion of the vascular tunic. The ciliary body is a dark brown structure and contains melanin-producing melanocytes. Other structural components of the ciliary body are ciliary processes and ciliary muscle. The ciliary processes arise as protrusions or folds on the internal surface of the ciliary body.

miss jennifer is buying pencils in packs of 12, notebooks in packs of 16, and red pens in boxes of 20. she needs to have the same number of pencils, notebooks, and red pens. how many packs of each type should she buy?

answer mine : )

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
