    There are many ways in which substances can move across the cell membrane and in which then helps in the function of the body (cells‚ tissues and organs) overall. There are 3 processes that a substance can move across the membrane‚ theses are diffusion (simple and facilitated)‚ osmosis and active transport. Both diffusion and osmosis are passive processes‚ which mean they do not need energy to occur‚ whereas active transport does require energy. All three processes are involved in many functions

    we look at science is the use of chemicals‚ explosions‚ experiments‚ etc. What we don’t really see is how science is related to any sport. The use of these science laws plays a big part in the way sports are played. Newtown’s laws of motion and the laws of thermodynamics set great examples in a tennis match to help us gain more knowledge in how they’re being used on earth. Newtown’s first law of motion is when force is being applied. If an object is left by itself it won’t move or change its state

    Plasma membranes are selectively permeable. The purpose of this experiment is to reveal how a form of diffusion in a semipermeable membrane works by creating a real life simulation of a semipermeable plasma membrane. This is done by building an imitation of a caterpillar’s digestive tract using dialysis tubing and glassware. The first material in this experiment is a small beaker representing the head and crop of the caterpillar. This beaker is filled with both starch and the enzyme α-amylase. This

    Another industry related to the second law of thermodynamics is the air-conditioner. As the weather in this country‚ Malaysia is always hot and humid‚ air-conditioners are used to cool down the surrounding inside the house. In fact‚ the concept of air-conditioner is one of the applications of the second law of thermodynamics which stated that for any process occurring in a closed system‚ the entropy increases for an irreversible system and remains constant for a reversible system‚ but never decreases

    starch across a selectively permeable membrane through a process of diffusion. The movement of a solute through this membrane is called dialysis . Diffusion is a form of passive transport. It is the movement of molecules from areas of higher concentration to those of lower concentration‚ until there is an even concentration. This movement is random because it is a result of kinetic energy. Diffusion is a slow process‚ but there are many factors that will affect it’s rate. The rate of diffusion will

    Identify Laws of Motion and Thermodynamics The first example is oscillating a pendulum‚ which is categorized in the law of motion due to the object remaining in that state unless an external force is applied. The second example stating cooling food and drinks in a refrigerator is categorized in the laws of Thermodynamics due to thermalization. The third example of using the coffeemaker can be a combination of both laws due to moving touching to coffeemaker to make create an action is Law of Motion

    Starch Diffusion in a Caterpillar’s Digestive Tract The object of this particular experiment is to gain knowledge on diffusion across a plasma membrane‚ which is selectively permeable. Diffusion is the movement of a substance from a region of high concentration to lower concentration. Experiment 2 was performed to see how the substance’s‚ starch‚ and diffusion process across a plasma membrane is affected by amylase. We prepared a simulated digestive tract of a caterpillar‚ as the plasma membrane‚ to

    Corollary 1: The clausius statement of second law of thermodynamics is the first corollary i.e. ‘It is impossible to construct a device operating in a closed cycle that performs no effect other than the transfer of heat from a cooler body to a hotter body.’ The mathematical statement of which is given by; Q1‐Q2=W Q1 W Q2 Corollary 2: It is impossible to construct an engine operating between only two heat reservoirs‚ which will have a higher efficiency than a reversible heat engine operating between
