Bio 101- Introduction to Biological Sciences I. Brief History of Biology. List down the contribution(s) of the following philisophers/scientists to the science of Biology Pre-historic people: The earliest humans must have had and passed on knowledge about plants and animals to increase their chances of survival. This may have included knowledge of human and animal anatomy and aspects of animal behavior (such as migration patterns). However‚ the first major turning point in biological knowledge

Theories of Biology pg.1 The major theories of biology are evolution of natural selection‚ biological classification‚ inheritance‚ cells‚ bioenergetics‚ homeostasis‚ and ecosystems. Evolution by natural selection is a process that occurs over successive generations. Inheritance is a theory of how characteristics of one generation are derived from earlier generations. Cells theory is that all organisms are composed of cells and that all cells come from preexisting

Beetroot Cells with High temperatures and low pH solutions Friday 15th March 2013 Abstract (50) The aim of this investigation was to study the effects of temperature and a low pH solution on beetroot cells. Introduction (200) The general belief amongst our group members was: an increase in temperature will damage the permeability of the plasma membrane. Also‚ the heat will break away the permeability. If the pH solution is 7 or greater there will be no change but the lower the pH the more proteins

supply electricity to cities in the late 1880s is often called the ’War of Currents ’‚ as this battle ultimately decided which type of current became the standard for the generation of electricity today. Due to different advantages and disadvantages‚ Edison promoted direct current (DC) for electric power distribution‚ whereas Westinghouse and Nikola Tesla both advocated alternating current (AC). Edison ’s direct current was initially the standard for the United States for electricity distribution

for some of the modern conveniences of today‚ Thomas Edison and Nikola Tesla. Edison perfected the incandescent light bulbs and devised a system of electrical current for homes and businesses. Tesla’s biggest innovation was introducing alternating current as the standard for modern electric power‚ breaking Edison’s monopoly on direct current power. Inventors Thomas Edison and Nikola Tesla were opposite sides of the same coin. Edison‚ a brilliant business man with no formal education and Tesla‚

Current Situation The image of professional baseball has‚ by and large‚ been an idyllic and relatively unblemished one from its roots as the national pastime in the mid-1800s until the latter part of the 20th century. Aside from the 1919 Black Sox scandal in which eight members of the Chicago White Sox conspired to cheat‚ to "fix" the World Series‚ nothing has rocked the game as much as the use of performance enhancing drugs (PED). Since revelations about players using such substances as steroids

In Biology 1115‚ I learned a great deal about cytoskeleton. I have been able to recognize the functions of molecular structures which are microtubules‚ microfilament and intermediate filaments‚ but I still have confusion about those structures. For example‚ I always misunderstand the differences between microtubules and microfilament. Therefore‚ I got wrong in some multiple choices of this midterm. I went back to the notes and read them again after seeing my midterm which can help me to clarify and
