The reflex involved when you stroke an infant's cheek and she/he turns toward the stimulator and begins to suck is called the rooting reflex.
The rooting reflex is one of the baby’s involuntary movements that help them find breast or a bottle to begin feeding. It occurs when the baby’s mouth touches the skin and as a consequence turn their heads. This reflex is typical for the first few months of baby’s life.
A substance floats if it is less dense, or has less mass per unit volume, than other components in a mixture. For example, if you toss a handful of rocks into a bucket of water, the rocks, which are dense compared to the water, will sink. The water, which is less dense than the rocks, will float. Basically, the rocks push the water out of the way or displace it. For an object to be able to float, it has to displace a weight of fluid equal to its own weight.
Water reaches its maximum density at 4 C (40 F). As it cools further and freezes into ice, it actually becomes less dense. On the other hand, most substances are most dense in their solid (frozen) state than in their liquid state. Water is different because of hydrogen bonding.
