CYCLES IN BIOLOGY This essay will give examples of cycles in biology from different scales of magnification‚ ranging from molecular level to populations and ecosystems. Cycles are sequences of events which repeat themselves in the same order‚ one event leading to the next. There are many examples of these in Biology. Cycles can be seen even at a molecular level in the body. An example of this would include the passage of action potentials down neurones in the nervous system. When the cell membrane

STAGES OF A BUSINESS CYCLE RECESSION A recession—also sometimes referred to as a trough—is a period of reduced economic activity in which levels of buying‚ selling‚ production‚ and employment typically diminish. This is the most unwelcome stage of the business cycle for business owners and consumers alike. A particularly severe recession is known as a depression. RECOVERY Also known as an upturn‚ the recovery stage of the business cycle is the point at which the economy "troughs" out and starts

INTRODUCING WITH BIOCHEMICAL CYCLES Biochemical cycles Nutrients are important for organisms to function. Each nutrient has a role in global biogeochemical cycles. A nutrient is a chemical that organisms need to live and grow and are substances an organism’s uses for metabolism which must be taken in from its environment that enrich the organism. Two types of nutrients are macronutrients and micronutrients. Macronutrients are needed in large quantities while micronutrients are needed in smaller

Mexico’s Business Cycle The term business cycle or economic cycle refers to the fluctuations of economic activity around its long-term growth trend. It involves shifts over time between periods of relatively rapid growth of output-recovery and prosperity‚ and periods of relative stagnation or decline- contraction or recession. These fluctuations are often measured using real gdp. Despite being termed cycles‚ these fluctuations in economic growth and decline do not follow a purely mechanical

4Action of hormones in the Menstrual Cycle The Ovarian Cycle The cycle begins with the release from the hypothalamus of gonadotrophin – releasing hormone (GnRH)‚ which stimulates the pituitary to secrete small amounts of Follicle Stimulating Hormone (FSH) and Luteinising Hormone (LH). The FSH stimulates follicle growth‚ aided by LH and the cells of the growing follicles start to make estrogen. Notice in figure(d) that there is a slow rise in the amount of estrogen

Otto Cycle When you talk about the Brayton cycle‚ gas turbine engines should come up and when you’re talking about the Otto cycle‚ piston engines should also come up. These two cycles are the backbone of power generation. The theory of the two cycles goes all the way back to the 18th century. The Name Brayton comes from the American inventor George Brayton and Otto comes from German engineer Nikolaus Otto. Both these men changed the world and how we live life now a day. The Brayton cycle was first

The Cell Cycle -Life of cell = divided into 3 stages called cell cycle. -Stages = Interphase‚ Mitosis and Cytokinesis -Interphase= cells carry out functions necessary for survival and cells that divide prepare for reproduction. -Mitosis divides duplicated contents of cell’s nucleus

Shipping Market Cycles The four most expensive words in the English language are‚ ‘This time it’s different’. (Sir John Templeton‚ quoted in Devil Take the Hindmost‚ Chancellor 1999‚ p. 191) 3.1 INTRODUCING THE SHIPPING CYCLE Market cycles pervade the shipping industry.

When they are low I feel bad’.1 Just as the weather dominates the lives of seafarers‚ so the waves of shipping cycles ripple through
