Answer : Option D
Explaination / Solution:
Towards the centre of the innerconcave surface of the kidney is a notchcalled hilum through which ureter, bloodvessels and nerves enter. Inner to the hilumis a broad funnel shaped space called therenal pelvis with projections called calyces. The medulla is divided into a few conical masses projecting into the calyces. Thus, 7, 9, and 10 are pelvis, hilum and calyx respectively.

Q4. Dalton’s Law of Partial Pressures states that the total pressure exerted by the mixture of non-reactive gases is equal to the
Answer : Option D
Explaination / Solution:
The question is based on the statement of Dalton Law of Partial pressures for Gases which states that total pressure exerted by mixture of non reacting gases is equal to the sum of partialpressure of individual gases.
Q5. For dissolution of gases in liquids, the concentration of a gas in liquid is.
Answer : Option C
Explaination / Solution:
For dissolution of gases in liquids, the concentration of a gas in liquid is proportional to the pressure of the gas over the liquid

Q8. The point at which exponential phase ends and decelerating phase begins is called
Answer : Option D
Explaination / Solution:
An inflection point is a point on a curve at which the sign of the curvature (i.e., the concavity) changes. Inflection points may be stationary points, but are not local maxima or local minima.
For example, for the curve plotted given, the red point is an inflection point.
