Background of the Study Janitor fish used to be aquarium pets. They would parade around the fish tank and clean the moss and other dirt that would scatter around the tank. Then‚ someone said‚ “If janitor fish are so effective in cleaning fish tanks‚ then why don’t we put them in the Marikina River so they can clean up all of the dirt?” Unfortunately‚ his hypothesis didn’t work‚ and now‚ janitor fish are the most abundant fish in the Marikina River. In this case‚ being an abundant species isn’t

Without oxygen‚ life itself would be nonexistent. Imagine what would happen if wounds did not get better‚ incisions did not heal‚ and burns did not improve. This is where hyperbaric oxygen therapy (HBOT) comes into play. Oxygen is necessary for the replenishment of tissues‚ healing of the body and assisting with general ailments. HBOT is used for a wide variety of treatments usually as requested in a medical care plan (Society‚ 1996). In this paper I will introduce what hyperbaric oxygen therapy

THE PERIODIC TABLE HISTORICAL BACKGROUND The idea that all things are elements or combinations of elements can be found in the writings of the ancient Greeks and other early peoples. Although this idea may seem simple‚ it is very difficult to decide if a substance is indeed an element or a compound. There were twelve chemical elements discovered in ancient times‚ but it was not known that they were elements. Another 76 elements were discovered between 1557 and 1925. Many mistakes were made in

Clown fish are remarkable creatures from their origin‚ to the habitat they live in‚ and even the way they reproduce. With their vibrant orange and white colors they are one of the most unique fish ever to be researched. They live in the most dangerous depths of water‚ with the sea anemone which they are always seen to be with. The Clown Fish also known as Anemonefish come from all over from the tropical Pacific Ocean‚ Red Sea‚ Indian Ocean‚ and the Australian Great Barrier Reef. They live near a

Ventilation and Oxygen Consumption in Fish Methods: The lab consists of two experiments repeated over a period one hour with fifteen minutes interval‚ in order to determine the effect of weight and temperature on ventilation and oxygen consumption of Carassius auratus‚ commonly known as goldfish. Each experiment was carried out by five groups. Measurement of ventilation was determined by recording operculum movement of the fish. Oxygen consumption was measured using oxygen probes.

Bottled Water and Tap Water The quality of water that we drink is a significant determinant of our health. Guarantee of the safety of water is a base for the prevention of diseases. Several people prefer to drink bottled or commercial mineral water in the presumption that they are safer and have quality as compared to tap water. I believe that tap water is the best choice for a few different reasons‚ Bottled water is very popular and easily available at most stores. Consumers spend a large

the sunlight and use it to produce nutrients for the cell. During this process‚ water molecules are broken down into oxygen and hydrogen atoms which are then released in the air. In the very early days of life‚ Earth was populated only by anaerobic bacteria that didn’t need oxygen to survive. When cyanobacteria first made their appearance and started engaging in their photosynthetic reactions‚ large amounts of oxygen were suddenly released in the atmosphere. This lead to what is known as the Great
