Examples of variable regulated by homeostatic reflex arcs are: Body Temperature Blood pressure Arterial PO2 and PCO2 Arterial pH Plasma Glucose Plasma Na+‚ K+‚ Ca2+ And many more.

Introduction: Every muscle has lactic acid.According to many people Lactic acid is nasty stuff produced in our muscles during exercise‚ cause soreness‚ muscle fatigue‚ does not contribute to exercise performance‚ muscle does not use it for fuel‚ and better athletes makes less of it. But they all are wrong or in other words they are a lay. Instead Lactate acid is made of Lactate ion called (Lactate) and Hydrogen Ion. C3H6O3----->C3H5O3++H- C2H3OHCOOH--------->C2H3OHCOO+ +H- Hydrogen ion is the acid

Brief history of demand curve and supply curve According to Hamid S. Hosseini‚ the power of supply and demand was understood to some extent by several early Muslim economists‚ such as Ibn Taymiyyah who illustrates- “If desire for goods increases while its availability decreases‚ its price

correct‚ the Urea was unable to diffuse though such a small membrane. 3. Describe the results of the attempts to diffuse glucose and albumin through the 200 MWCO membrane. How well did the results compare with your prediction? We predicted that glucose and albumin would both diffuse very slowly through the 200 MWCO because they are large molecules. The results were; the glucose diffused through the 200 MWCO membrane at a rate of 0.0040 per minute. The albumin was not able to diffuse through the 200

1 Practical report: Determination of concentration using a standard curve Introduction Spectrophotometer is an instrument that confirms the measurement of specified wavelength of light that passes through medium. The measurement of light absorbance by a solution is also done with spectrophometer. Absorption spectrum Spectrometers are mainly and widely functional in identifying the components of solutions that helps determine the components’ concentrations. Compounds are experimentally identified

STANDARD DEVIATION The standard deviation is a popular measure of variability. It is used both as a separate entity and as a part of other analyses‚ such as computing confidence intervals and in hypothesis testing. The standard deviation is the square root of the variance. The population standard devia¬tion is denoted by σ. Like the variance‚ the standard deviation utilizes the sum of the squared deviations about the mean (SSx). It is computed by averaging these squared deviations (SSX/N) and

1. What is trading standards? What impact can they have on your business? Trading Standards is the name given to local authority departments in the UK formerly known as Weights and Measures. Frequently‚ the Trading Standards enforcement functions of a local authority are performed by a small part of a larger department which enforces a wide range of other legislation: environmental health‚ health and safety‚ licensing and so on. 1 What you sell There are a few general laws that affect all consumer-facing

The animal will be missing trioodythronine and thyroxine. 4 If an animal has been hypophysectomized‚ what effect would you expect to see in the hormone levels in its body? Due to the rat’s missing pituitary gland‚ TSH will be missing.
