They alse distribute their weight evenly that way the weight is no concentrate in just one place. 43. Why do cells need buffers? Cells need buffering agents for various reasons. The main reason is that these buffers neutralize the solution to maintain the PH.
It is important to correct the readings from the peas because the glass beads are used as a control in which no changes should occur in CO2 and oxygen levels due to their abiotic nature. 3. For both plants and animals, cellular respiration occurs not only during the daytime but also at night. However, cellular respiration cannot occur if there are not enough reactants to carry out the process. For example, because plants supply an abundant amount of oxygen to the atmosphere, it would be difficult for living cells in humans to respire if plants were ever to be demolished from Earth.
The alveoli passes the oxygen to the blood capillary by diffusion (high – low) and this is also how the waste (carbon dioxide) is passed back to the lungs to be breathed out this is why there is only a thin membrane so it can be passed through easily. Also diffusion is the movement of molecules from a region of low concentration until the concentrations are equal. When the air enters the body the upper airway (from the nostrils to the vocal cords), the sinuses either warm or cool the air that has been breathed in depending on the weather you have breathed in e.g. if it is hot it will cool the air down and if it’s cold it will warm the air

Many people come to the notion that they may want a pet without fully understanding how to properly take care of the animal. The only way for your pet to really thrive in your home is to have a grasp on what the natural environment of the animal is. For the leopard gecko, this is relatively simple. The leopard gecko is one of the hardier geckos out there and do not require a great deal of upkeep, making them suitable pets for nearly anyone. As you will soon find out, setting up and maintaining a proper living environment for a leopard gecko is not a great deal of trouble at all.
A disadvantage of this system is the by product which is lactic acid which makes the muscles sore. A positive of this energy system is also that it can be done both aerobically and anaerobically. After about five minutes of exercise, Aerobic Glycolysis is the dominant energy system. Aerobic Glycolysis produces energy by breaking down muscle and liver glycogen stores with oxygen present. Because oxygen is present when this system is in use, there is no build up of lactic acid.

The level of osmotic pressure is equal in the intracellular fluid, and the extracellular fluid.’ (Study.com, 2015) ‘Osmotic pressure is vital within the human body because it allows water to enter a cell if there is lack of water, and vice versa, if there is too much water within one cell, the osmotic pressure will allows the electrolytes to exit a cell.’ (Study.com, 2015) ‘Intracellular fluid has important functions, it transports food within the cells, it also brings waste products from the cells so that they can be picked up and excreted from the body, and it maintains the shape and size of the cell.’ (Nursing411.org, 2015) ‘Extracellular fluid is located outside the body cells. The extracellular fluid consists of one-third of the water contained in the body. The extracellular fluid has many functions; it carries nutrients and oxygen to the body cells and waste materials from the cells. There are two types of extracellular fluid, including interstitial fluid and intravascular fluid.’
P2- Different concept of health What is Health: Health is the word used to describe how your body feels, being healthy is important because it makes you feel good and live longer.

What if we could rid our human species of these imperfect traits? What if every new human offspring was guaranteed to be strong, healthy, and intelligent? The world would be rid of struggles like heritable diseases and genetic mental retardation. The human race could always produce perfect offspring. There would be no dysgenics or deleterious genes to deteriorate our gene pool as the population grew.
