REVIEW SHEET‚ EXAM 3 Chapter 6‚ Nutrition and Microbial Growth Define the four major modes of nutrition in microorganisms and distinguish among them in terms of energy and carbon sources The four major modes of nutrition are: 1. Photoautotrophs: (ex. Plants‚ some protozoa‚ & alegae) -microorganism which use carbon dioxide as a carbon source and light energy from the environment to make their own food. 2. Chemoautotrophs: -microorganism which uses carbon dioxide as a carbon source and

Licton Industrial Corporation‚ which specializes in the production of plastic‚ located in Valenzuela City‚ Philippines. Tensile strength was tested with the 2cm x 1cm part of the film and 0.12 mm thickness. As a result‚ the tensile strength of the biofilm is 232 MPa. The result shows that the film lasted for 1 second with the force of 340.5000 g and was converted to 232 MPa which resulted to low tensile strength.

Taylor Rock Professor Johansen ENG 105 27 March 2015 Climate Change: Plastic Pollution Of the 32 million tons of plastic produced annually‚ only 9% of plastics are recycled globally. The question then becomes‚ where does all this plastic end up? The answer is our oceans. The United Nations has noted that there is an estimated 50‚000 pieces of plastic in every square mile of the ocean (United Nations). Charles Moore first discovered plastic pollution in the ocean in 1997. Unlike the commonly believed

Types‚ Effects‚ and Controls of Air Pollution Air pollution depending upon which source you use is broken down in a couple of ways. No matter how you look at it though‚ air pollution is still air pollution and it is both harmful to humans and the environment. One source breaks air pollution down into two categories or seven primary and two secondary pollutant types (Wright & Boorse‚ 2008‚ p. 487). The primary pollutants can more easily be broken down into four types of pollution which are based

multifactorial influenced by genetics as well as by the environment [1]. Periodontitis is characterized by persistent inflammation‚ connective tissue breakdown‚ and alveolar destruction [2]. It is initiated by specific bacteria within the plaque biofilm and progresses due to an abnormal inflammatory immune response to those bacteria [3]. It is the major cause of tooth loss and is significantly associated with an increased risk of stroke [4]. Pockets form between teeth and gum‚ making anaerobic region

Periodontal disease has the potential to cause systemic effects‚ including preterm delivery and low birth weight; therefore‚ dental professionals must be aware of these risks in order to properly treat and educate pregnant women. This editorial will review the risks that the inflammation process imposes on a fetus. A healthy pregnancy is important not only for the mother’s health‚ but also for the baby’s health. As healthcare providers‚ dental hygienists have a responsibility to educate pregnant
