1. A patient with poorly controlled Type I diabetes has blood drawn and finds that the pH of his blood is 7.1. The normal pH of blood is 7.4. The patient’s blood [H+] is A) one fourth normal B) one third normal C) half normal D) twice normal E) three times normal 2. The Henderson-Hasselbalch equation: A) allows the graphic determination of the molecular weight of a weak acid from its pH alone. B) does not explain the behavior of di- or tri-basic weak acids C) employs

CELLS All living things are made of cells‚ and cells are the smallest units that can be alive. Life on Earth is classified into five kingdoms‚ and they each have their own characteristic kind of cell. However the biggest division is between the cells of the prokaryote kingdom (the bacteria) and those of the other four kingdoms (animals‚ plants‚ fungi and protoctista)‚ which are all eukaryotic cells. Prokaryotic cells are smaller and simpler than eukaryotic cells‚ and do not have a nucleus. Prokaryote

Michelle Gordon‚ TJ (Group 4) Section 33 Yeast Cell Respiration 10/04/2010 Part B: Explanation of Results All cells carry out the process of cell respiration in order to meet their energy needs. It is advantageous for cells to have the ability to metabolize different substrates. In this experiment‚ we investigated each sugar’s (glucose‚ lactose‚ sucrose‚ fructose‚ and lactose/lactaid) cell respiration rate. When referring to my group’s graph and data‚ glucose ended up with the highest

Essay Question 1 Explain how changes in habitat can lead to habitat fragmentation. How does this affect the population of animals in that area? Species lose their habitats when those habitats are destroyed outright‚ but habitat loss also occurs when habitats are altered through more subtle processes‚ including fragmentation and other forms of degradation. The sudden and complete elimination of habitat is uncommon at large scales; instead‚ what we usually witness is gradual‚ piecemeal degradation

After months of research and experiments‚ I have concluded my discovery of space worm touch receptors is definite. Regardless of the type‚ sensory receptors are influenced by physical actions and various stimulus. My research and experiments show that space worm touch receptors are no different. Stimulus is a change discernible by the body (Sherwood 2004) or in my case‚ a space worm. Certain receptors like touch receptors respond to stimulus weakly or strongly when involved with a different stimulus
