Light initially enters the eye through the cornea, it protects the eye and helps to focus light rays into the retina at the back of the eye. The passage of light continues through the pupil which looks like a black circle in the centre of the eye. The pupil is not a structure itself but helps to control the amount of light entering the eye. The iris surrounds the pupil, is the coloured part of the eye. It is a ring of muscles which expand or contract to change the size of the pupil and control the amount of light. The optic nerve carries the visual information from the retina to the primary visual cortex. The optic nerve exits the eye at the back of the retina, the same point where blood vessels enter and exit the eye.
Micelles were constructed for the delivery of a hydrophobic chemotherapeutic drug. An increase in the length of the acyl chains used to make them would increase the diameter of the micelles.
Micelles have been probed as drug delivery carriers for decades. Their use can potentially result in high drug accumulation at the target site through the enhanced permeability and retention effect. Nevertheless, the absence of stability of micelles in the physiological environment limits their effectiveness as a drug carrier.
Many measures to enhance the stability of micelles have concentrated mainly on decreasing the vital micelle-forming concentration and improving blood circulation. Compared with other drug delivery strategies, micelles have two unmatched benefits. First is their relatively small size. Second is their feasibility of large-scale manufacture.

Evolution for humans means how they adapted over time. it has made humans live longer, healthier, have higher education, and live higher standards.
Phenotypically and genotypically there are only two different ratios. If you think of a Punett square...
<span>You could say that a pea plant with the trait for the dominant color green (G) could also carry the recessive trait for yellow (g). So let's say you mate a dominant green, (Gg) with another dominant green, (Gg). You would get 1 (GG), 2 (Gg) and 2 (gg). </span>
<span>Phenotypically (as in physical traitwise), the ratio is 3:1 because you have 3 green colored peas and one yellow. </span>
<span>Genotypically (as in traitwise), the ratio is 1:2:1, because you have 1 (GG), 2 (Gg) and 1 (gg). </span>
<span>So although it's random, for any specific trait there are only 4 different outcomes.</span>
