Answer:
We all know that air contains lots of microbes in it and it can be proved by putting a plate containing broth media in open air. After some time microbes will appear on the plate.
In this question, there is two flask a normal flask that is open to the air and a swan neck flask with a curved neck to limit air movement. So in normal flask which is open to air microbes can easily be transmitted into the flask through the air but the swan neck flask does not allow air movement in the flask, therefore, no microbe can enter into the flask.
Therefore due to contamination through air open flask shows immediate signs of rotting and the presence of microorganisms. So contact with air is the reason for the presence of microorganism in the open flask.

Answer: The correct answer is C. 62.5%
Explanation:
Since the two drugs have equal affinity for the same receptor, when both are present at the same time in maximally effective concentrations, one half of the receptors will be occupied by the first drug and one half by the second drug. Since the intrinsic activity of the first drug is 1.0, each receptor occupied by this drug will be activated 100% and therefore the total response of one half of the receptors will be 50% of the maximal response. By the same token, since the Intrinsic activity of the second drug is 0.25, each receptor occupied by this drug will be activated 25% and so the total response of the other half of the receptors will be 12.5% of the maximal response. Therefore the response of all receptors will be 50% +12.5%, that is 62.5 % of the maximal response.
