Structure and function of macromolecules within a living organism ‘Some biological molecules in organisms are small and simple containing only one or a few functional groups‚ others are large‚ complex assemblies called macromolecules’ [1]. The term macromolecule is convenient because the bulk properties of a macromolecule differ from those of smaller molecules. These large chemical compounds have a high molecular weight consisting of a number of structural units linked together by covalent

Describe the key structures and functions of a eukaryotic and prokaryotic cell. Eukaryotic Cell (1) There are many organelles in the eukaryotic cell micrograph above. Some of these organelles are displayed in the prokaryotic micrograph and so‚ I have described the shared organelles in the prokaryotic micrograph section. Mitochondria The mitochondria cells break down nutrients which then creates energy. They act like a digestive system. This process is called cellular respiration. The

ways that we humans have adapted to the physical environment in which we live in? Such as plate tectonics‚ weathering and erosion‚ and the form of precipitation. How do/can we adapt to nature and its disaster? PLATE TECTONICS: Plate tectonics causes earthquakes‚ which are one of the things that we have to adapt to. Earthquakes are powerful and each time it strikes it separated the land. So over time we as humans have created strategies. To keep us safe and how to remain calm as the earthquakes

Lipids make unglazed paper‚ such as the outside of a paper bag‚ translucent. Phospholipids have a very similar structure to triglycerides. However‚ in phospholipids‚ an additional functional group containing a phosphate group replaces one of the fatty acids. They are the main component of the cell membranes of every cell in

psychological traits such as perception‚ memory‚ and language as adaptations. This approach is focused on how evolution has shaped mind and behavior. Michael Ghiselin coined the term evolutionary psychology‚ making him a key theorist. Other key theorists include Jerome Barkow‚ Leda Cosminde‚ and John Tooby. These three popularized the concept of evolutionary psychology with their book “The Adapted Mind: Evolutionary Psychology and the Generation of Culture.” This approach views behavior as an evolutionary

Coronary heart disease is the buildup of plaque in the heart’s arteries that could lead to a myocardial infarction. However‚ coronary heart disease‚ or CHD‚ is actually a result of coronary artery disease‚ or CAD. With coronary artery disease‚ plaque accumulates within the walls of the coronary arteries until the blood flow to the heart is limited‚ causing ischemia. It may be chronic‚ caused by narrowing of the coronary artery over time. It can be acute‚ resulting from a sudden rupture and formation

Coronary artery bypass graft surgery (CABG) is an advance surgical method meant for treating coronary heart diseases or CHD. In coronary artery bypass surgery‚ healthy veins or arteries from different parts of the body are grafted around the heart or onto the blocked aorta. These grafted portions bypass the blocked areas of the artery and thus create a new route for the blood to reach the heart. Coronary artery bypass graft surgery or CABG is one of the most popular open heart surgery methods performed

Coronary Artery Bypass Graft (CABG) is performed when a patient has disease of the coronary arteries. This is usually caused by atherosclerosis which is clogging of the arteries or hardening by cholesterol of plaque. Coronary Artery Bypass is done to improve the blood flow of the heart. The surgeon bypasses the obstructed artery using a healthy artery that is harvested from another part of the body and placed in the heart to reroute the blood flow around the blocked area. Usually the healthy vein is taken

“How Does the Body Function?” Do you consider your body a delicate temple‚ and do you give any thoughts to the daily functions it provides for you? Well‚ to name a few‚ the eyes‚ ears and skin play a vital role in our lives‚ and without these precious body parts I believe our life of living free would be limited. Someone once said that “the eyes provide a window to the soul‚ they also provide us with a window to the world.” Our vision starts when you look at an object; the light from
