These contain hemoglobin, an iron-containing protein, which facilitates transportation of oxygen by reversibly binding to this respiratory gas and greatly increasing its solubility in blood.

These fruit versions sometimes contain colored pearls ( and / or " jelly cubes " as in the related drink taho ), the color chosen to match whatever fruit juice is used.

These neighborhoods contain most of the area's residential buildings, along with park space and various types of supporting businesses ( supermarkets, restaurants, movie theaters.

These were some of the first reinforced concrete buildings, and their plans did not contain enough details ( such as how much reinforcing bar had been embedded in the concrete ) to be sure they were safe, so the engineers recommended demolition.

These contain about 80 % ground granulated blast furnace slag, 15 % gypsum or anhydrite and a little Portland clinker or lime as an activator.
