Q1. The number of degrees of freedom a monatomic molecule is
Answer : Option A
Explaination / Solution:
Degrees of freedom of a system refers to the possible independent motions a system can have.
Monoatomic gas molecule can have 3 independent motion and hence have 3 degrees of freedom (all are translational).

(i) Migrate
(ii) Suspend
(iii) Regulate
(iv) Conform
Column II
(a) hibernation and aestivation
(b) sweat it out
(c) inability to maintain a constant internal environment
(d) people going from Rajasthan to Kashmir during summer
Answer : Option D
Explaination / Solution:
People going from Rajasthan to Kashmir during summer is a kind of migration. During hibernation and aestivation organism suspends life proceeses to minimum levels. To regulate the body temperature sweating occurs and inability to maintain consistent internal environment is called conformation.

Q7. Antibodies in our body are complex
Answer : Option B
Explaination / Solution:
Antibodies in our body are present in the blood in form of glycoproteins. They produce antigens in response to foreign particles to provide immunity against the pathogen.
Q8.
Mg2+ is isoelectronic with
Answer : Option D
Explaination / Solution:
Isoelectronic species refers to the elements that have the same number of electrons.
Mg2+ is a 10 electron species .Its configuration is like that of Ne.
Thus it is isoelectronic with any element having 10e- or we can say 8e- in its valence shell.
Atomic number of Sodium (Na) is 11 after loosing one electron it became Na+ and have 10 electron.
Thus Mg2+ is isoelectronic with Na+.
Q9. Sound becomes hazardous noise pollution at decibels-
Answer : Option B
Explaination / Solution:
No Explaination.
