They replace the lost ions by active uptake through active transport
of ions from the surrounding waters. This is exhibited in freshwater fishes that
actively take in these ions through the gills. Most of the ions involved in osmoregulation in freshwater are those of Na+ and Cl-.
The types of rock that can form sediment when they are weathered is D. Igneous, sedimentary and metamorphic. (When the molten rock cools it forms an igneous rock. Metamorphic rocks can form from either sedimentary or igneous rocks. The sedimentary particles from which a sedimentary rock is formed can be derived from a metamorphic, an igneous, or another sedimentary rock. All three rock types can be melted to form a magma.)
<span>The
exact location of Lower Egypt using the coordinates in a map as a guide is
30.60 degrees to the North and 31.10 degrees to the East. The borders were not
specifically divided during the Ancient Egypt but Egyptians based its relationship
to the area of the Upper Kingdom.
Lower Egypt mostly consists of major cities
that were built along the river Nile. Memphis, Alexandria, Hermopolis, among
others are Lower Egypt’s major cities. Cities were built in this area because
when the River Nile breaks its banks each year, the soil around the area is
ideal for crop growing. The famous Pyramids of Giza are also found in Lower
Egypt. </span>
