Answer:

Because they are avascular.

Explanation:

Superficial skin does not have adequate blood supply so it does not bleed and this is reason why a cut on the superficial skin or when a hair is  pulled dose not results in bleeding.

It involves the epidermal part of the skin which is not properly supplied with blood vessels. So any cut or hair pulling from this region has no bleeding.

Basically because your skin has several layers to it (see link, below), and the layer that has the blood vessels capable of bleeding in it is further down than a superficial scrape would affect.

Cancer cells are different because they don't enter the G - 0 phase and they are likely to do which of the following Your answer
Allisa [31]

Answer:

c) repeat the cell cycle continuously

Explanation:

Cell division is a normal phenomenon for all cells as this is the way the cell reproduces and gets repaired in living organisms. However, some cells, due to mutation, keeps dividing and proliferating to form tumours. These cells are called CANCER cells. A normal cell undergoes cellular repair at certain checkpoints of the cell cycle. The checkpoints are necessary to determine a faulty cell and stop its division.

However, cancerous cells do not undergo any repair, which is why they do not enter the G0 phase as mentioned in the question. They keep on dividing out of control without death by repeating the cell cycle continuously.
