function properly, a proper pH level of the blood must be maintained at 7.4. Buffers refer to a solution containing a mixture of weak acids and salts of their corresponding bases. The optimum value of the pH is maintained by buffer system made up of three types. The buffer maintains the blood pH by adjusting the pH level, that is, increasing the acidity if the pH rises above the optimum value of 7.4 or taking up the hydrogen ions when the pH of the blood lowers below the optimum value. In this context, we will discuss the intracellular and plasma buffer system and how it function. Bicarbonate buffer system is the predominant buffer system that operates in the blood plasma. In essence, this buffer...

function on the given intervals. f (x) = 2-x3 on Solution To find the critical points, take derivative: f’(x)=-3x2 f’(X)= 0 0=-3x2 X=0 For absolute minima and maxima; f(0)=2-(0)3=2 f(-2)=2-(-2)3=10 f(1)=2-(1)3=1 Therefore: abs minima =1 at x=1 Abs maxima=10 at x=-2 (d) Calculate the limits of the following limx→0x+5x2 Solution Divide both numerator and denominator by x2 =lim x->0 1/x+5/x2 Since we have 0 in the denominator, the limit=0 (e) evaluate A'(x) at x = 1, 2, and 3. A(x) = -3x 2t dtSolution =d/dx(t2) At x=1; (12)-(-32) =-5 At x=2; (22)-(-32) =-2 At x=3;(32)-(-32) =12 (f) . Let A(x) represent the area bounded by the graph and the horizontal...

functioning issues concerning the "Change of Mind" documentary and "Sing Unburied" novel. Effects of Brain Injury on Society Brain injury not only subject victims to sufferings but also the entire society is adversely affected. The condition deprives the society productive human resources and also leads to the society incurring financial costs. Victims suffer mood swings and losses concentration which makes them lose their jobs (Pyror, 2016). Consequently, such individuals may engage in criminal activities to earn a living hence incurring financial problems to the society. What interventions could be helpful to this population in determining Brain Injury? The society has a role to play in...

functions of various organs (Zamora-López, Zhou, & Kurths, 2011). Some of the common attributes include thinking and control of homeostasis. For the brain to do all these functions, the brain is divided into some parts. On the lower side, there is a link between the spinal cord and the brain called the medulla oblongata or myelencephalon. This regulates the reflex responses responsible for controlling involuntary functions such as heartbeat and breathing. Above the medulla are the cerebellum and pons. The pons is accountable for transferring information to the higher parts of the brain while the cerebellum process information from sensory nerves and facilitate body movements. Above the two is...
