False
Alkaline is something we use everyday
Acid is something sour eg lemons
If you don't wash the thermometer, residual NaOH will react with the HCl solution. This is a highly exothermic reaction and will change the temperature of the solution, and thus throw off your measurement.
Answer:
spinal cord
Explanation:
The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord.
Increasing the temperature of a gas sample means that heat energy is been supplied to the System. When energy is been supplied heat energy is transformed into kinetic energy of the gas molecules.
Therefore kelvin temperature increases means more energy given to the system therefore average kinetic energy of molecules increase.
When the kinetic energy of molecules increase they move about more and take up more space. Hence volume too increases.
Therefore the correct answer is
4) average kinetic energy of molecules increase and volume of the gas sample increases
Answer:
A. 2,3 BPG
Explanation:
2,3-bisphosphoglycerate (BPG), otherwise known as 2,3-DPG, enables the transition of hemoglobin from a very high-oxygen-affinity state to a reduced-oxygen-affinity state.
Tissues hemoglobin oxygen affinity is reduced by numerous physiological factors including.
1. Temperature Increased,
2. Carbon dioxide,
3. Acid and
4. 2,3-Bisphosphoglycerate (2,3-BPG)
all of which can contribute to decrease the oxygen affinity of hemoglobin which favours unloading and increased oxygen availability to our body cells.
