If your babyâs newborn screening result for phenylketonuria (PKU) was out of the normal range, your babyâs doctor or the state screening program will contact you to arrange for your baby to have additional testing. It is important to remember that an out-of-range screening result does not necessarily mean that your child has the condition.

Tape grass (Vallisneria americana) and hydrilla (Hydrilla verticillata) are rooted in the sediments. Coontail (Ceratophyllum demersum) and bladderwort (Utricularia spp. ) are free-floating. Some submersed species (tape grass) produce flowers and are pollinated underwater or at the waterâs surface.at-tail plants are found at the waterâs edge and can grow to a depth of 1 to 3 meters (3 to 10 feet). Emersed plants are rooted in water-saturated soils or submersed soils near the waterâs edge. The leaves and stems grow above the water. During low-water conditions, emersed plants can grow in exposed, damp, sediments.
