Harvesting solar energy as a source of power Photosynthetic microorganisms, such as micro-algae and cyanobacteria are able to harness low-intensity solar energy and store it as latent chemical energy in the biomass. This energy can then be released via biochemical conversion. The structural and storage carbohydrates in biomass have low energy content and it is necessary to concentrate the energy content further for fuel application. Anaerobic microbial fermentation is an efficient and widely used

Richard Ching Biology 141 Exam 1 Study Questions 1-15 1. What is the difference between an hypothesis and a scientific Theory? Between an hypothesis and a prediction? What kinds of hypotheses are useful for scientific investigations that try to explain the natural world, and which are not? Give one or more examples of hypotheses that are and are not scientifically useful. A scientific theory is an explanation for a broad class of phenomena or observations, whereas a hypothesis is a testable

Vincent McConnell BIO 102 research paper- Tinea Pedis (Athlete’s Foot) 9-18-14 Tinea is a fungus that grows and multiplies on people’s skin. This is the cause for ringworm and other common fungal infections. Tinea Pedis is a form of ringworm that affects the feet, also called Athlete’s Foot. This fungal infection is the most common form of the ringworm infection and affects many people daily. It is easily spread through any contact with the infection but luckily it can usually be diagnosed rather

Tube # 16 Colonial characteristics of the broth (3pts): The morphological unknown colonial characteristics consist of small and round shapes. It forms a shiny texture with entire margins and a convex elevation. In addition, the color is yellow-tan. Gram reaction (5pts): The morphological unknown is gram-negative. Shape (4pts): The shape of the morphological unknown is coccobacillus. For example, the unknown is rod-shaped (Bacillus) yet short and rounded or spherical (coccus). Arrangement

Respiratory Disease Paper Shonay Williams HCS/245 September 9, 2014 Susan Fahrney Respiratory Disease Paper Pneumonia is an infection of the lungs that can be caused by either a bacteria, a virus, or fungus. The alveoli or (air sacs) fill up with fluid and pus and then become solid. This disease would be considered a tertiary disease. It is classified as a tertiary disease because it is an end result of some other types of infections or illnesses. The flu is one of the main illnesses that

more common with animals due to animals eat more raw meat then a average everyday person. The bacteria’s survival is based on conditions with very little or no oxygen. The toxin it generates causes the food borne illness. Clostridium perfringens bacteria grows in food after it has been cooked. If foods such as poultry or beef are not cooked at the recommended temperature and not kept at a temperature that is either warmer than 140°F or cooler than 41°F, clostridium perfringens can easily set in.

Lab Safety against Pathogenic Bacteria Considering that there are still a lot of unknown bacteria, it is really important that in lab when handling bacteria extreme precaution is taken towards handling them and to treat them as pathogenic. Today it is an acknowledged fact that anyone in the laboratory whether they are researchers, scientist, or students must follow all guidelines and safety rules for their safety. Every laboratory has its own lab safety equipment and guidelines such as dress code
