This is due to the fact that nails are not actually some useless piece of accessory on your hands.
Nails actually have several components. The nails actually cover something called the keratogenous Matrix, which is the whitish membrane with nerves, and blood vessels that decide on how far nails grow, and is protected by the nail plate which what you can see. The Lunula or the whitish bit of the nail is actually transparent.
On the other hand you have hair which is a verticle object usually used for aesthetic purposes and is an alive thing until it goes above the skin. Hair which is normally aesthetic does have some purposes in different parts of the body. The eyelashes are designed to keep particulates out of the eye, while the axillary hair, is used for thermoregulation (the hair in the armpits and groin are what makes up the axillary).
Explanation:
The cardiovascular system pumps blood throughout the body. As the blood is circulating out of the heart it is filled with oxygen and nutrients. These nutrients get divided to the rest of the cells in the body. As the blood is coming back into the heart the urinary system takes the waste out of it.
So basically, it basically acts as a delivery system delivering O2 and nutrients and takes waste out of the cell.

Answer:
The controversial No Child Left Behind Act (NCLB) brought test-based school accountability to scale across the United States. This study draws together results from multiple data sources to identify how the new accountability systems developed in response to NCLB have influenced student achievement, school-district finances, and measures of school and teacher practices. Our results indicate that NCLB brought about targeted gains in the mathematics achievement of younger students, particularly those from disadvantaged backgrounds. However, we find no evidence that NCLB improved student achievement in reading. School-district expenditure increased significantly in response to NCLB, and these increases were not matched by federal revenue. Our results suggest that NCLB led to increases in teacher compensation and the online gokkasten share of teachers with graduate degrees. We find evidence that NCLB shifted the allocation of instructional time toward math and reading, the subjects targeted by the new accountability systems.
