Introduction Succession is the measurable process in which a community changes and thus the community as a whole is altered (Friedman 2017). To study succession‚ one must use one of the following methods: to observe any patterns that occur‚ to conduct experiments that manipulate specific variables in a community‚ or to construct a model that may undergo succession. One example of an experiment that measures microbial succession was an experiment observing changes in traditional Chinese soy sauce

of the experiment was to acquire data for the mass change resulting from osmosis in order to determine the carbohydrate solution of the carrot cells. The carrots were a vegetable used within the experiment with a carbohydrate solution around .5 M. The hypothesis is if there are carrots in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic solution is .2 M and 0 M‚ around

at Ohio State and into the beginning of his teaching career as a psychologist at Harvard then Stanford. His smoking was so bad he eventually was smoking three packs a day. That is just crazy to think someone can smoke three packs in just one day‚ but I also think someone smoking one pack in a day is crazy too. Mischel realized that smoking could kill him‚ but his attempts to quit smoking all failed. He would quit then start smoking again just like when most people try to quit something and can’t so

process separates lignin from cellulose fibers. This is accomplished by dissolving lignin in a cooking liquor‚ so that it may be washed from the cellulose fibers. This preserves the length of the cellulose fibers. Paper made from chemical pulps are also known as wood-free papers–not to be confused with tree-free paper. This is because they do not contain lignin‚ which deteriorates over time. The pulp can also be bleached to produce white paper‚ but this consumes 5% of the fibers. Chemical pulping processes

in business. There’s less chance that there will be any misunderstanding because you are communicating both verbally and non-verbally. It is not always practical to speak to somebody face to face i.e. if they are on the other side of the world. In this case communicating over the telephone can be useful but more over its important in business to get a balance of both of these forms of communication. Verbal communication is enormous. Using speech can help express complex ideas. Although without speech
