Mixed Solutions: If 1 mmole of glucose (180mg=1mOsm) and 1 mmole of NaCl (58mg=2mmOsm) are put into a beaker and distilled water added to make 1 liter, the osmolarity is 3 mOSm/L. OSMOSIS CALCULATIONS: 1. Calculate the number of grams of NaCl needed to prepare 100 mL of a 280mOsm.L Solution. (280mosm/l) *(1L/1000mL)*(100mm/1)*(29mg/1mosm)*(1g/1000mg)=0.812g 2. Calculate the number of grams of glucose needed to prepare 100mL of a 280 msm/L glucose solution.
tract? Which cells are direct participants in formation, and how do they contribute to lesions in the G.I. tract wall? c. Zach’s stomach contributes to the formation of ulcers by the acids needed to breakdown food when they are excessive. Parietal cells (secrete HCI) and gastric glands (acetylcholine) are directly related to the formation of ulcers.
Undigested food travels into the large intestine. Excretes non-absorbed material passed from the small intestine. Water absorption. Stores waste and house bacteria that make vitamin K. Rectum – Feces are stored in the rectum before being expelled along the anal canal. Liver – Major role in dealing with the nutrient products of food digestion.
Stores and concentrates bile 19. Filters the blood coming from the digestive tract. Detoxifies chemicals and metabolizes drugs, secretes bile and makes
Plants are the producers for an ecosystem. They photosynthesise carbon dioxide and water and produce energy in the form of carbohydrates and other molecules. Photosynthesis requires water, and plants gain water from the soil using mineral ions such as nitrate produced by the nitrifying bacteria. Hydrolysis of ATP releases energy for processes such as active transport of the nitrate ions (and others such as potassium etc) from the soil into root hair cells, a process that lowers water potential and is used to draw water into the plant from the soil. In leaves, photosynthesis involves the photolysis of water, a process that involves the attachment of two electrons to a magnesium ion in chlorophyll and the production of hydrogen ions from the breakdown of water.

What is a function of the lymphatic system g. Absorb digested fats h. Produce & Mature immune cells i. Reabsorb extracellular fluid & Return it to the bloodstream j.
Lab 3: Aseptic Technique and Culturing Microbes Task: A. Describe the difference between an obligate and facultative aerobe. The difference between the two is Obligate aerobe requires oxygen to be present in order to grow an organism. With Facultative aerobe the organism does not necessary need oxygen to survive. It can live and grown with or without oxygen.
