Answer: Between 8 and 14
Explanation: Ammonia is an inorganic compound of formula NH₃. Also known as ammonium hydroxide, it behaves as a weak base.
pHydrion paper is a chemical test indicator, i.e., it indicates the pH of a substance.
If inserted in Ammonia, pHydrion will indicate a range of 8 to 14 because in pH scale, indication of base is over 8 and up to 14. The exact number depends on the hydrogen ion concentration of the substance.
Options for the question have not been given. They are as follows:
blood vessel length
blood viscosity
blood vessel diameter
blood colloid osmotic pressure
Answer:
blood colloid osmotic pressure
Explanation:
- Peripheral resistance is the resistance to blood flow by blood vessels.
- It is directly proportional to blood vessel length as more the distance to travel, more will be the resistance.
- It is also directly proportional to blood viscosity as more energy is required to push viscous material.
- It is indirectly proportional to blood vessel diameter. More the diameter of the vessel, easier it is for the blood to pass.
- However, it does not depend on blood colloid osmotic pressure. Colloid osmotic pressure is created by the protein components of blood and they do not have any direct impact on blood flow.
