The Henry's Law constant for oxygen dissolved in water is 4.34 xx 10 ^(4)atm ( mol /L) at 25^(@) C . If the partial pressure of oxygen in air is 0.2 atm under ordinary atmospheric condition calculate the concentration (in mol/litre ) of dissolved oxygen in water equilibrium with air at 25^(@) C

Endocrine glands control and co-ordinate the body functions through secreting certain chemical messengers called hormones. Due to certain physiological reasons, the blood glucose level of otherwise normal persons increases. How can this condition be reveresed?

Take a small stone. Hold it in your hand. We know that the force gravity due to the earth acts on each and every object. When we were holding the stone in our hand, the stone was experiencing this force, but it was balanced by a force that we were applying on it in the opposite direction. As a result, the stone remained at rest. Once we release the stone from our hands the only force that acts on it is the gravitational force of the earth and the stone falls down under its influence. Whenever an object moves under the influence of the force of gravity alone, it is said to be falling freely. Thus the released stone is in a free fall. In free fall, the initial velocity of the object is zero and goes on increasing due to acceleration due to gravity of the earth. During free fall, the frictional force due to air opposes the motion of the object and a buoyant force also acts on the object. Thus, true free fall is possible only in vacuum. For a freely falling object, the velocity on reaching the earth and the time taken for it can be calculated by using Newton's equations of motion. For free fall the initial velocity u=0 and the acceleration a=g . Thus, we can write the equations as v="gt",s=1/2"gt"^(2),v^(2)=2gs For calculating the motion of an object thrown upwards, acceleration is negative, i.e. in a direction opposite to the velocity and is taken to be -g. The magnitude of g is the same but the velocity of the object decreases due to -ve acceleration. The moon and the artificial satellites are moving only under the influence of the gravitational field of the earth. Thus they are in free fall. Which force acts on the stone in free fall after you release it?

Ramu was 15 vears old when he went to a doctor to check his blood pressure. His pressure was around 158/98mmHg. The doctor advised him to measure his blood pressure at home for two weeks. He came to the doctor saying his average blood pressure was around 160/100mmHg. Doctor concludes that Ramu has high blood pressure or hypertension. If not controlled, hypertension can lead to heart failure, stroke and kidney failure. He returned to the doctor after two months after taking the drug, ACH inhibitor. This chemical blocks the production of angiotensin II, a powerful vasoconstrictor, so his blood pressure returned back to normal. 1. Why are people with high blood pressure at greater risk for having a hemorrhagic stroke? 2. Without medication Ramu's blood pressure was around 160/100mmHg after two weeks. Why this pressure was referred to as hypertension by the doctor. 3. Blocking the action of vasoconstrictor lower the blood pressure? Give reasons. 4. What is the role of ACH inhibitor in reducing blood pressure? 5. What conditions one might expect if the blood pressure is not controlled?
