When people talk about the color of one’s eyes, they are actually talking about the color of the a. sclera b. iris c. cornea d. lens

B. iris

Explanation:

Eye color is produced due to melanin pigmentation in iris and light scattering by iris's stroma. It is a polygenic character i.e. it is controlled by multiple genes. Melanin pigment in iris can range from light brown to black. Colors like blue, green or hazel are produced due to Tyndall scattering of light by stroma. There are no blue or green pigments in iris.

Eye color can also change with age. Many European new born babies are born with light colored eyes. As they grow, melanocytes in iris start to produce the melanin pigment which can lead to color change. Puberty, pregnancy and serious trauma can also lead to iris color change.

the answer is 1. photosynthesis. glad to

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
