Groundwater refers to the water present underground, in the spaces and cracks in the sand, soil, and rock. It is accumulated in and moves gradually through the geologic creations of sand, soil, and rocks known as aquifers.
The groundwater supplies drinking water to about 51 percent of the total population of the United States and 99 percent of the rural population. Almost 64 percent of the groundwater is utilized for irrigation purposes, and it is also a source of recharge for rivers, lakes, and wetlands.
Hence, the correct phrases that describe groundwater are feeds rivers, used for irrigation, and provides drinking water.

Answer:
Tetraploid wheat evolved by allopolyploidization and subsequent diploid-like behavior due to cytological diploidization
Explanation:
Durum wheat (<em>Triticum durum</em>) or pasta wheat, is a tetraploid wheat species that has 28 chromosomes, i.e., seven pairs in each genome (2n = 4x = 28). Durum wheat was domesticated from wild emmer wheat, which originated by hybridization of two diploid wheat species with 14 chromosomes: <em>Triticum monococcum</em> (genome AA) and one wild progenitor (genome BB). <em>Triticum durum </em>is a typical example of evolution by hybridization and polyploidization, where the resultant tetraploid species has two complete sets of chromosomes. Allopolyploidization is one of the most common types of plant speciation. During meiosis, 28 chromosomes form 14 homologous chromosome pairs, because homologous chromosomes have developed 'restriction of pairing' (i.e., cytological diploidization). The restriction of pairing to fully homologous chromosomes ensures a correct meiotic behavior, which otherwise would be altered due to the high level of homology that still exists among chromosomes from different wheat progenitors.
