Hookworm eggs are found in the stool of infected dogs and cats. When the eggs hatch, the larvae can infest soil and vegetation. When you come into contact with this infested soil, the larvae can burrow into your skin. They cause an intense inflammatory response that leads to a rash and severe itching.
A pint of blood in America sells to hospitals for $180 to $300, depending on the market, and expired blood often is sold to research laboratories, said Ben Bowman, chief executive of General Blood, the blood broker engaged in a legal tussle with Oklahoma City-based OBI.
1 pint of whole blood weighs about a pound. Source(s): California medical research center. Seems like a good deal of confusion as I got several answers from 1.1 pound to 1.5 pounds. The density of blood is about 1.04 g/cc, so 450 ml of blood should weigh about 468 grams. Despite blood having so many components, the density is very close to water. They either take 450 or 500 ml out when you donate blood.
