highest rates and that lactose was the lowest‚ so we see a clear downwards sloping trend‚ which was also expected. This suggests that yeast respires best with glucose instead of sucrose fructose or lactose. To explain this process‚ we must first understand how sugar affects yeast growth. First of all yeast is a fungus‚ meaning that it needs sugars to supply it energy. Yeast can also release oxygen like human beings‚ called respiration. So technically speaking the more sugars there are the more

By Introduction: Last Thursday‚ September 16 of the current year‚ we the student of the Dalubhasaan ng Lunsod ng San Pablo(DLSP) had our “Educational Trip” to Subic‚ Olongapo. Aside from the Ocean Adventure at Subic‚ Olongapo‚ we also went to Nayong Pilipino at Clack‚ Pampanga and in Barasoain Church and Museum at Malolos Bulacan. The aim of this educational trip is to broaden the knowledge of students in the different fields of learning. Here is a brief discussion of what the trip was all

Population Ecology: Clover Distribution and Density Method This lab consisted of the use of various materials. We used four orange flags in order to mark a 30x15m sampling area in which we collected our data from. To measure out the area‚ we used a thirty meter measuring tape and to determine the density (plants per meter squared) of clovers in the lawn‚ we calculated the total area of the plot (30x15meters squared). For this lab‚ a frisbee was used with the area of .053 meters squared as the

America’s most prominent and problematic issue. Population growth‚ the U.S. population is growing by over 2‚000‚000 people per year‚ 240 people per hour‚ about half from new births and half from immigration. An issue that not only devastatingly impacts our economy‚ but is rapidly depleting our environment. Such as‚ the Central Valley Aquifer which loses the water equivalent of 1 Lake Mead each year. The underlying factor catalyzing the rapid growth in population was the swift progression in technology.

Abstract Population genetics is the study of how localized groups of individuals capable of interbreeding and creating fertile progeny change genetically over time. The Hardy-Weinberg equilibrium accounts for gene pools that do not change genetically over time. In this experiment‚ I intended to determine whether the sample population consisting of my fellow biology lab classmates would fall in the Hardy-Weinberg equilibrium with respect to the ALU insert from human chromosome 8. My hypothesis was

eighteenth century saw a population explosion in England and Wales with the English populace growing from 5.05 million in 1701 to 8.7 million in 1801. The population level was reasonably inert in the first half of the century with only an increase to 5.77 million in 1751‚ the main population growth occurred from 1751 until the mid nineteenth century‚ by which point it had reached a staggering 16.8 million. There is debate by historians as to whether the growth in population over this period is due

more relaxed in spite of the mounting evidence for global climate change. 2. Explain the main point concerning exponential growth and whether it is good or bad. Compare exponential growth to a logistic growth curve and explain how these might apply to human population growth. What promotes exponential growth? What constrains population growth? The population growth is dependent and thus proportional to the birth rate‚ which is the main variable.

Making Bread with Yeast By Rebecca Coles Introduction Bread is such a common food‚ who would expect it to be made in such a fascinating and clever way? A simple loaf contains just four main ingredients; flour (the main ingredient)‚ warm water (the yeast prefer the water warm)‚ salt and of course the yeast‚ tiny microscopic fungi that help the bread rise. Although fascinating the process is surprisingly simple; first‚ the flour‚ sugar and water is mixed together with yeast to make the bread
