Discussion in 'Questions From New Drivers' started by JazWife, Oct 27, 2008. Hubby does NOT get direct Deposit of his paycheck for a few weeks. Not sure why that is, but anyways...he received an authorization or comcheck for his first week of work ..... and I've NEVER heard of this, so I'm pretty confused. He filled out the check with his name and the amount, then called a number to register it.
Bacteria can be divided into following types on the basis of use of oxygen: Aerobic: which require oxygen for their growth they can be: a. Obligate Aerobic: survive only if oxygen is present example; Mycobacterium tuberculosis. b. Microaerophile: That require lower amount of oxygen i.e. 2 to 10% example; Helicobacter pylori. 2. Anaerobic bacteria; which do not require oxygen for their growth they can be; a. Obligate Anaerobic; which are harmed by presence of oxygen , they can not survive in presence of oxygen. Example: Clostridium tetani, C. perfringens. b. Facultative anaerobic bacteria; can grow without oxygen, but use oxygen if it is available to produce energy.
Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight into chemical energy. There are two types of photosynthetic processes: oxygenic photosynthesis and anoxygenic photosynthesis. Oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria. During oxygenic photosynthesis, light energy transfers electrons from water (H 2 O) to carbon dioxide (CO 2), which produces carbohydrates. In this transfer, the CO 2 is reduced, or receives electrons, and the water becomes oxidized, or loses electrons. Ultimately, oxygen is produced along with carbohydrates. Oxygenic photosynthesis functions as a counterbalance to respiration; it takes in the carbon dioxide produced by all breathing organisms and reintroduces oxygen into the atmosphere.
