The basic geohydrology of the Edwards aquifer in the Balcones fault zone is, by now, well understood and has been capably described by many authors, especially Arnow (1959), Abbott (1975), Maclay and Small (1984), and Senger and Kreitler (1984).ONCLUSIONS AND RECOMMENDATIONS. 1. There are two Edwards aquifers in Texas, one in the Edwards Plateau and the second in the Balcones fault zone area. Both are fractured, cavernous aquifers developed in carbonate rocks that were deposited in very shallow-marine shelf environments.
Pinworm infection, also known as enterobiasis, is a human parasitic disease caused by the pinworm. The most common symptom is itching in the anal area. This can make sleeping difficult. The period of time from swallowing eggs to the appearance of new eggs around the anus is 4 to 8 weeks.
Reproduction based on the number. Unicellular organisms are single celled forms whereas multicellular organisms are made up of many cells. Depending upon the complexity of the body, reproduction in unicellular organisms is different from that of multicellular organisms. 1  Unicellular organisms reproduce by asexual means.2  This asexual mode of reproduction involves single parent to produce their offspring. Amoeba is a simple, unicellular organism which reproduces by transverse binary fission. 2  The division begins with the division of nucleus. 3  Binary fission can also be observed in multicellular animals like sea anemones and planarians. 4  Binary fission observed in Leishmania is longitudinal binary fission.
