How microscopes have contributed to our understanding of living organisms There are 2 types of microscopes these are; light microscope and electron microscope. Light microscopes use a beam of light however the resolution is lower than the electron microscope so the image is not clear‚ however they can view living organisms. These types of microscopes are used in schools to view simple cellular structures‚ which is good to teach simple biology Mitosis and meiosis can be seen with light microscopes

This assignment will describe the role of energy in the body and explain the physiology of two named body system in relation to energy metabolism. It will explain where energy comes from‚ how the body uses energy‚ what is metabolism/catabolism and anabolism and also it will explain cellular respiration aerobic/anaerobic is. Energy is necessary for muscular activity and movement however‚ energy is also necessary to circulate blood and lymph and tissue fluid throughout the body; for breathing and

the reality of my choices. I want to share a bit of what I have learned about nutrition. And please‚ do not take my word for it. I encourage you to ask questions. Look beyond the first few results from search engine queries. Seek out articles‚ papers‚ and documentaries that provide objective‚ expert opinions‚ and references. Keep an open mind‚ use your intuition‚ and follow the facts. For instance let’s evaluate a common belief like‚ "Vitamins and Supplements make for very expensive urine"

Ng Boon Yee/ Group B06/ A0099215Y Comparison of Organisms from the Class Oligochaeta and Class Chilopoda Animal phylogeny is an interesting and rapidly changing field of study. To date‚ there are about 1.5 to 1.8 million species of animals that have been named and described by biologist with 15‚000 to 20‚000 new species named each year. However‚ millions more species are yet to be discovered and classified. Taxonomists have divided the animal kingdom into about 35 phyla (Solomon et al.‚ 2011). Out

BS0005-Physiology PRACTICAL(2010/11) : Measuring Body Parameters Introduction: Physiology is the study of the functions of living organisms. In this physiology practical‚ measurements of 41 students’ weight (kg) using electronic weighing scales‚ height (cm) using height measuring scales‚ skin fold thickness using callipers (mm)‚ heart rate by counting pulse rates were made and then these results were tabulated on an excel sheet. The aim of this practical is to deduce how students’

REVIEW SHEET EXERCISE 6 Cardiovascular Physiology NAME: LAB TIME/DATE: 1. Define each of the following terms: • autorhymicity- The heart is autorhythmic. This means it generates its own rhythmic action potential independent of the nervous system. • sinoatrial node- is the impulse-generating (pacemaker) tissue located in the right atrium of the heart‚ and thus the generator of normal sinus rhythm. • pacemaker cells- are specialized cells that cause involuntary muscles and tissues to

When the stimulus is delivered‚ the ermeability of the membrane at that point is changed; and c ‚ initiating the depolarization of the membrane. Almost as soon as the depolarization wave has begun‚ a repolarization wave follows it across the membrane. This occurs as b . Repolarization restores the h of the resting cell membrane

(4) uses of energy in biological processes (B); active transport; muscle contraction; nerve transmission; synthesis; translocation; nitrogen fixation; receptors ENERGY TRANSFERS WHICH TAKE PLACE INSIDE LIVING ORGANISMS Living organisms including all plants and animals require energy for their cellular processes. In biological processes‚ the immediate energy source is often in the form adenosine triphosphate (ATP). The nucleotide ATP maintains both catabolic and anabolic reactions. An example of
