The following is a sample of the type of exams that I will be giving in class. Try completing this exam in 45 minutes. This should be roughly half the size of your exam. Nick 1) Which of the following pairs is mismatched? a) immunologist – studies ecology of Legionella pneumophila b) virologist -- studies human immunodeficiency virus c) Microbial ecologist -- studies bacteria that degrade oil d) Microbial physiologist – studies fermentation of sourdough bread e) Molecular biologist

inside and outside of the egg is equilibrium. It has a situation where we can say that Hypotonic occurred‚ because the water moved into the egg. The egg placed in the syrup solution loss 38% of it’s weight. Fructose is a concentration gradient and it diffuse‚ so the water gets out of the egg till the concentration outside and inside of the egg is equilibrium. It has a situation where we can say that Hypertonic occurred‚ because the water moved out of the egg. The egg in the distilled water gained

1.0 Definitions of Sepsis ! Sepsis is often referred to as either blood poisoning or septicaemia. Sepsis occurs when an infections spreads through the blood‚ causing symptoms to develop throughout the whole body. It is where the body’s defence mechanisms respond to an infection in some part of the body which resulting in symptoms such as fever‚ hypothermia‚ heart rate greater than 90 beats per minute‚ altered mental status‚ swelling of the extremities‚ and high blood glucose in diabetic

highest concentration solutes….resulting in a volume increase Osmotic pressure(closed system)(mmHG)‚ the more impermeable the higher the osmotic pressure Tonicity(shrink or swell); how a solution affects the volume of a cell Isotonic: same inside and outside Hypertonic: higer

| Percent changes = Final mass – Initial mass/Initial *100 Conclusion: Our result show that is so strange because the final mass(g) of each solution going increase and some decrease.It was hard to conclude that which solution is isotonic‚hypertonic and hypotonic.however‚ we notice that 100% water final mass is quite the same as initial mass becasue at the first time we mass the weight are the same and for the second time the weight were decrease.Also‚ I prediction that final mass of 0

concentration. Active transport- requires chemical energy Passive transport- requires no energy because the molecules move from an area of high concentration to one of low concentration. Hypertonic environment- there’s a net movement out of the cell. Isotonic environment- there’s no net movement Hypertonic environment- there’s a net movement into the cell. Asexual reproduction- the process of producing offspring from only one parent; the production of offspring that are genetically identical

membrane may only occur with a few substances such as oxygen‚ carbon dioxide‚ and alcohol. Osmosis is the diffusion of water across a selectively permeable membrane. When osmosis occurs in the plasma membrane the molecules will move from hypotonic to hypertonic. Facilitated Diffusion is polar molecules and ions impeded by the lipid bilayer of the plasma membrane diffusing passively with the help of transport proteins that span the membrane.

Osmosis and Diffusion During the past few weeks in my Ag Biology class we have been learning about and reviewing both osmosis and diffusion. We did two different labs‚ one on osmosis; the other on diffusion. The first lab we did was our diffusion lab. We learned that diffusion is moving something from an area of high concentration to a low concentration. We were showed that Mio and other flavor drops perform diffusion when put in water as an example. For the lab part we put a mixture of starch

Professor Kristin Latzo Nutri‚ Health‚ & Wellness w/ Lab 8 February 2014 Water: An Overlooked Essential Nutrient Welcome‚ I am a registered dietician. I have invited you to lunch and learn about‚ what you will select for a yearlong beverage contract from these three choices water‚ Gatorade‚ and Powerade. The role of water in our body are giving cell life‚ where water is a carrier‚ distributing essential nutrients to cells as minerals‚ vitamins‚ and glucose. It also has chemical and metabolic

surrounding the cell there will be a dynamic equilibrium between the number of water molecules entering and leaving the cell‚ hence the cell does not change size. For example‚ red blood cells in the blood plasma retain their shape because of the isotonic nature of the plasma. If the concentration of water is higher within the cell then that of outside the cell‚ there will be a net movement of water out of the cell‚ this will cause the cell to shrink and shrivel. Within animal cells there is no
