“The energy for life comes from the sun.” Outline the role of the photosynthesis process to explain what is meant by this statement. (3 marks) chlorophyll 6CO2(g) + 6H2O(l) + energy C6 H12 O6 (aq) + 6O2(g) 2830 kJ glucose Photosynthesis is the process in which plants use the sun’s light energy to convert carbon dioxide and water into carbohydrates such as glucose‚ sucrose‚ starch and cellulose. Carbohydrates are high energy compounds

Conservation of Energy Aim The aim of this lab experiment is to observe the flow behaviour of water through a pipe of variable section. Firstly‚ we will investigate the interchange of pressure and kinetic energy at each diameter change. Secondly‚ we will study the application of this interchange to the flow metering devices. Lastly‚ energy losses due to friction and pressure effects are estimated. Experimental Apparatus [pic] Pre-lab Question Pressure varies along the pipe. Explain why this

Does God Exist ? 1. What role do arguments play in answering this question? I think arguments have played an important role in analyzing and understanding the depth of this question‚ for mankind. Although the question itself seems factual (either it does or it doesn ’t)‚ yet no arguments have been able to answer this question conclusively‚ despite many debates going on for centuries. One possible reason for that inconclusiveness may lie in our intuition and the way‚ humans define God and existence

Why 1688 – 1832? Clavers got a clankie o’ to mere artificers Nation and state became disjointed then at the very time men and women of accomplishment were flourishing and‚ as stated‚ we find difficulty in determining when we think this began and when we think it became complete. Consequently‚ for our purposes‚ bearing in mind the general parameters just set out‚ the study of the Scottish Enlightenment and the learned men and women will begin with the Glorious Revolution of 1688.

Energy transfers which take place in living organisms The nucleotide ATP (adenosine triphosphate) maintains both catabolic and anabolic reactions. Catabolic reactions e.g. respiration are where larger molecules are broken down into smaller ones with energy being released‚ and anabolic reactions e.g. photosynthesis are where smaller molecules are built up into larger ones which require energy. Catabolism provides the energy for organisms to synthesise larger molecules in its anabolic reactions.

Design Argument--Does God exist? I found William Paley’s design argument in The Watch and the Watch-Maker the most compelling and thought provoking because I thought he had an interesting point symbolizing the watch as the universe and the watch-maker as the universe-maker or God. Paley doesn’t give a scientific explanation‚ but instead bases his work on observation and logical thinking unlike Robin Collins’s argument in his work‚ A Scientific Argument for the Existence of God‚ which is supported

molecules will gain kinetic energy allowing them to move a lot more frequently. Enzymes begin a reaction when they randomly collide with the substrate molecule‚ this is where the enzyme will react upon. The speed and frequency of these collisions is dependent on the temperature‚ so an increase in temperature will effectively increase the rate of reaction and allow more products to be made. Consequently‚ an increase in the temperature will make the vibrational energy that each of the molecules to

EXPERIMENT NO. 5 COMMON ION EFFECT Lopez‚ Pauline G. HIJ-2‚ Group No. 5‚ Ms. Jervee M. Punzalan Ramales‚ Ayane Mark Q. September 15‚ 2014 I. ABSTRACT The common ion effect involves how the solubility of a salt changes when some ion that is common to both added substance and the salt in question is introduced. The presence of a common ion hinders the ionization of a weak acid or a weak base hence this is known as the common ion effect. Simply put‚ the effect

Biology Homework Explain how blood sugar levels are regulated in your body. Blood sugar level (also known as blood glucose level) is the amount of glucose (sugar) in the blood. The amount of glucose in the blood is expressed as millimoles per litre (mmol/l). Blood sugar levels are tightly regulated in the human body. Glucose‚ transported via the bloodstream‚ is the primary source of energy for the body’s cells. The levels of glucose in the blood are monitored by the cells in the pancreas. If

[Energy resources]: The 2 broad types Pros and Cons of each type Ways in which they are harnessed There two main types of energy these are: 1. Potential energy 2. Kinetic energy Potential energy Potential energy is energy stored due to position. The following are some example in which potential energy can be found. 1. Wound-up spring When a spring of a dock work toy car unwinds‚ the stored energy in the spring drives the wheels and the car moves. The wound-up spring is said to posse potential
