COURSE: ADVANCED FISH NUTRITION (FIS 504) UNITS: 2 LECTURER: Dr. S.O. Obasa 1. Advanced principles of fish nutrition; i. Requirement for energy. *Sources of energy in fish feeds. *Differences in energy need between fish and other farm animals. *The implications of feeding fish with feed that has excess or deficient energy. ii. Protein requirement. *Functions of protein in fish. *Sources of protein in fish feeds. *Factors affecting protein requirement in fish. iii. Vitamins and minerals

Diffusion & Cell Size Lab Background The absorption of nutrients‚ excretion of cellular wastes‚ and the exchange of respiratory gasses are life processes which depend upon the efficient transport of substances into‚ out of‚ and throughout living cells. The process of diffusion can be easily visualized by adding a drop of blue food coloring to a glass of water. Initially‚ the food coloring remains in a small area in the water‚ dying it a dark blue. Over time‚ the molecules of food coloring

The Rainbow Fish Rainbow Fish‚ with his beautiful sparkling silver scales‚ was the most beautiful fish in the ocean. Despite Rainbow Fish’s beauty‚ he was not happy; this was because he had no friends. When he thoughtlessly hurt the feeling of one of his many admirers‚ the other fish in the ocean began to ignore him. Rainbow Fish’s beautiful scales are the most important thing in the ocean to him. Because of this he was faced to decide whether his beauty is more important than having friends. Rainbow

Brittany Snell Nielson Bio 110 Oct-11-2013 Cellular Respiration All living organisms need energy to function and we get this energy from the foods we eat. The most efficient way for cells to harvest energy stored in food is through cellular respiration. Cellular respiration is defined as the aerobic harvesting of chemical energy from organic fuel molecules. Cellular respiration occurs in eukaryotic and prokaryotic cells. It has three main stages: glycolysis‚ the
Premium Adenosine triphosphate Cellular respiration Metabolism
Cellular respiration is the process of obtaining energy in order to produce ATP. Cells obtain energy for their metabolic reactions. Cellular respiration includes both aerobic and anaerobic processes. Aerobic is when oxygen is consumed as a reactant and an aerobic is without oxygen. There are three phases in cellular respiration glycolysis‚ Krebs cycle‚ and the electron transport chain. Glycolysis is the first stage and

should burn and rage at the close of day”.(line 2) The main character in W.D. Valgardson’s short story “God is Not a Fish Inspector” does not share this perspective on life and death. It is not death that Fusi‚ the main character in the short story‚ wishes to avoid‚ but rather an inability to live. He refuses to stop fishing‚ defying his old body‚ his worried daughter and the fish inspectors because he believes that a person should be useful and vital. He believes that only a productive life is

The drug “dinitrophenol” (DNP) was prescribed by some physicians in the 1940’s to help patients lose weight. This unsafe method was abandoned after a few patients died. DNP uncouples the chemiosmotic machinery by making the lipid bilayer of the inner mitochondrial membrane leaky to H+. Explain how this could cause weight loss. In chemiosmosis‚ NADH are passed along the electron transport chain‚ with energy used to pump protons across the inner mitochondrial membrane. As the protons are transferred

God is Not a Fish Inspector There is no reason for me to stop fishing. I cannot stop‚ nor will I. Sure‚ there may be some discomfort‚ but I will never admit defeat to the elements. As long as I stand on my two feet‚ I will continue to fish‚ continue to inhale the fresh dawn air‚ and continue to feel the crisp morning breeze in my face. My mind is much too strong to lose to my body. If I wake up in the morning‚ I will cast my net‚ reel in my catch‚ and head for home‚ head back to my ungrateful

Measuring the rate of cellular respiration in yeast within different types of sugar Aim/Reasearch Question: How can the rate of cellular respiration be measured to find out if sucrose‚ dextrose‚ lactose‚ or maltose lets the yeast to respire more than others. Hypothesis: I think‚ dextrose yeast solution will respire the most number of bubbles because it is the simplest sugar to break.
