What 2 hormones are involved in regulating the blood calcium level?
Parathyroid hormone provides a powerful mechanism for controlling extracellular calcium and phosphate concentrations by regulating intestinal reabsorption, renal secretion, and exchange between the extracellular fluid and bone of these ions. Also, Calcitonin, which is a peptide hormone secreted by the thyroid gland, tends to decrease plasma calcium concentration and usually has effects that are opposite to those of the parathyroid hormone.
What change will be caused by addition of a small amount of HCl to a solution containing fluoride ions and hydrogen fluoride?
The concentration of fluoride ions will decrease and the concentration of hydrogen fluoride will increase.
Is there any way to increase or decrease the energy possessed by electrons?
You can increase or decrease the kinetic energy of electrons by accelerating or decelerating them, which you can do with an electric field or by collisions. You can increase or decrease the electrical potential energy of electrons by causing them to move to positions with lower or higher voltage. To a very small extent you can increase or decrease the gravitational potential energy of electrons by causing them to move up or down in a gravitational field.
When precipitation is less than potential evaporation what is likely to happen to soil moisture storage?
The soil moisture storage will decrease.
What is the relationship between the percentage change in mass and sucrose molarity?
Change in mass depends on the concentration of sucrose within the dialysis bags. If the concentration of sucrose is greater inside the bag than outside, then water will move into the bag. If the concentration of sucrose is lower inside the bag than outside, then water will move out of the bag.
What effect will Raising the potassium ion concentration in the extracellular fluid surrounding a nerve cell have?
Both hyperpolarize it and decrease the magnitude of the potassium equilibrium potential.
What happens to the equilibrium concentration of reactants when the volume of the reaction system is decreased and why?
decrease in reactants and increase in products
Effect of concentration of electrolyte on cell potential?
The potential of a cell can decrease if the concentrations of the solutions are less than 1.0M.N.B. The standard conditions for a galvanic cell involve the concentration of the solutions being 1.0M.
A decrease in input costs to firms in a market will result in?
a decrease in equilibrium price and an increase in equilibrium quantity
What effect does potassium have on the resting potential of a cardiac cell?
Hyperkalemia is an increase in extracellular K. Driving force of an ion depends on two factors, voltage and concentration gradient. For K voltage gradient is pushing K into the cell but the concentration gradient is driving K out of the cell. However, the total driving force for K is out of the cell because the concentration gradient is that strong. When there is an increase in K on the outside, the driving force for K decreases.The equilibrium potential for K is -95mV. This means if K was freely permeable to the cell's membrane, it would reach equilibrium at -95mV. Another way to look at this is that efflux of K is the same as influx of K and the cell's new resting membrane potential would increase from a normal value of -70mV to -95mV. Note that I said it would increase even though the value became more negative. This is because the change in membrane potential has increased.Since the driving force of K has decreased, the equilibrium potential has also decreased. From a value of -95mV it is decreased to let's just say -80mV. Since a normal resting membrane potential is regularly -70mV, the decrease in equilibrium potential of K has decreased this resting membrane potential to say -60mV now. This is a depolarization of the cell.If this process happens quickly, it will depolarize the cell to the threshold value and you will have an action potential. However, if the hyperkalemia is severe, the cell will stay depolarized because the K equilibrium has decreased to a point where the cell cannot hyperpolarize back to threshold or resting membrane potential.If this process happens slowly, the inactivation gates of the sodium voltage-gated channels will automatically shut and the cell cannot depolarize even if it reaches threshold values. It must hyperpolarize back to resting membrane potential and the inactivation gates of the sodium voltage-gated channel will reopen.
A decrease in supply will cause an?
increase in equilibrium price and a decrease in equilibrium quantity, which leads to a shortage at the original price.
How does hypoglycemia lead to hyponatremia?
when you have high levels of glucose in the blood (hyperglycaemia) this will draw water out of cells due to the increase in osmolarity. With increased water in to the extracellular fluid it will decrease the concentration of sodium (hyponatraemia)
How do you decrease the rate of isomerization of a chemical reaction?
It depends on what type of isomerization is occurring; configurational or stereoisomerization. Use of equilibrium concentrations and/or catalysis concentration strategies would work.
What will happen to the concentration of reactants after an equilibrium reaction shifts to the left?
Increasing the concentration of reactants will shift the equilibrium towards the products. The equilibrium will always shift to reduce the change you caused. If you add more products, it shifts toward reactants. This is known as the Le Chatelier Principle.See the Web Links to the left of this answer for more about this.
What is in the middle of decrease and increase?
equilibrium
A decrease in demand will have what effect on equilibrium price and quantity?
There will be a decrease in price and quantity.
Which substances decrease the hydrogen ion concentration in a solution?
Adding a base the hydrogen concentration decrease.
