Efferent neurons carry messages from the central nervous system. Neurons communicate through voltage changes. This can sometimes lead to quick action reaction sequence of voltage alterations. An example would be when you touch something hot and you pull your hand away immediately. One cell changes its voltage and the next

products C and D. However‚ unlike the common thought that the reaction ends when it runs out of A and B it actually does not. In most reactions C and D start to react to form A and B at a certain point as you can see in the equation c C + d D → a A + b B. These two reactions occur until the rate of reaction in both equations become equal (meaning the speed of the production of C and D in the first equation is equal to the speed of the production of A and B in the second equation) resulting in a

Factors that Determine the Currency Exchange Rates Exchange rate is often referred to as the nominal exchange rate. It is defined as the rate at which one currency can be converted‚ or ’exchanged ’‚ into another currency. For example‚ the pound is currently worth about 1.824 US dollars. One pound can be converted into 1.824 dollars. This is the exchange rate between the pound and the dollar. There are four types of currencies can be operated‚ which are a floating‚ managed and fixed exchange

Gel filtration GEL FILTRATION OF PROTIENS Aim: The aim of this experiment is to identify proteins from a complex mixture using the gel filtration technique also known as size exclusion chromatography. This technique is widely used by biochemists when proteins larger than the pores are excluded from the column and the smaller molecules elute last and then collected in test tubes for examination by spectroscopic techniques. The red/brown proteins‚ in particular‚ will be observed closely

Respiratory Rate and Tidal Volume [pic] The total amount of air moved in and out of the lungs each minute (pulmonary ventilation) depends upon 2 factors: size of each breath (tidal volume) and number of breaths/minute (respiratory rate). For example‚ suppose your tidal volume is 500 mL (0.5 liters) and you breathe 15 times/minute. Your pulmonary ventilation = 15 breaths/min x 0.5 L/breath = 7.5 L/min. Pulmonary Ventilation = (Respiratory rate; breaths per minute) x Pulmonary Ventilation

Chloride in Urine in Different Circumstances Aim: To determine the chloride content by titrating mixtures of urine against potassium thiocyanate under in different circumstances. Research Question: How do different conditions of urine samples collected affect its concentration of chloride which is measured by titrating the mixture of urine with potassium thiocyanate until it turns red? Hypothesis: The greater the consumption of food‚ the higher the chloride concentration in urine. This can

Hypothesis The group drinking water will have the highest rate of urine production. The group that drinks water only when thirsty will have the lowest rate of urine production. The specific gravity of urine for all treatment groups will be around 1.000. The pH for
