Pharmacokinetics is the analysis of how the body copes with absorption, distribution, metabolism & excretion of drugs under examination.
The four process of pharmacokinetics are absorption, distribution, metabolism and elimination.
Explanation:
Pharmacokinetics is the analysis of how the body copes with absorption, distribution, metabolism & excretion of drugs under examination. The impacts and length of the drug's action are also considered.
The four process of pharmacokinetics are absorption, distribution, metabolism and elimination.
1) Absorption - Absorption is the motion of a drug into the blood from its administration site. Many drugs are absorbed through passive absorption, but certain drugs require transportation mediated by the carrier.
2) Distribution - Distribution is the body wide motion of drugs
3) Metabolism - It is the method of transforming a drug throughout the body and make it much more hydrophilic in order for the kidneys to secrete it from the body.
4) Elimination - Excretion is the elimination from the body of the substance. Several drugs are either excreted unchanged or emit as urine or some other form.
Answer:
Explanation:
Stratospheric ozone is important because it acts as the blockade to harmful UV radiation directly from the Earth. If there were no stratospheric ozone then the life on the Earth was not possible because direct exposure to UV rays cause Skin cancer and many more health problems to humans and animals and plants. Thus, Stratospheric ozone is very important because it absorbs the penetration of harmful UV radiation as well as other harmful radiations. Whereas, the ground level Ozone becomes a harmful gas because it has adverse effect on the Human lungs. Old aged people, children, outdoor working people etc. mostly get effected in their breathing and taking smooth air from the environment.
The role of Ozone depletion in the stratosphere by the CFCs is very crucial because 1 molecule of CFC can destroy 100,000 molecules of Ozone by a simple chemical reaction in the presence of UV. More the CFCs in the environment and in the Stratosphere cause more Ozone depletion. And, this may lead to penetration of harmful UV rays into the Earth surface.
When the connection between CFCs and ozone depletion was well understood, many of the people (scientists, business persons, public, politicians) started to adopt the tecchnology which do not produce CFCs. Till few years ago, our refrigerator, AC and other instruments used to produce enough CFCs but, nowadays this has been significantly reduced. Similarly, the burning of plastics and other CFCs producing fuels has been banned or reduced. All the concerned authorities made strong rules to reduce CFCs in the environment and in the Atmosphere. And, this led to decrease in the depletion of Ozone on the stratosphere.
Its B , cause its the build up of magnetic energy that is suddenly released ,causing what we see and call a solar flare and it looks like a bright light coming out of the representation
