Match List I with List II:

List I	List II
A. Logistic growth	I. Unlimited resource availability condition
B. Exponential growth	II. Limited resource availability condition
C. Expanding age pyramid	III. The percent individuals of pre-reproductive age is largest followed by reproductive and post reproductive age groups
D. Stable age pyramid	IV. The percent individuals of pre-reproductives and reproductive age group are same

A. A-II, B-I, C-III, D-IV B. A-II, B-III, C-I, D-IV C. A-II, B-IV, C-I, D-III D. A-II, B-IV, C-III, D-I

Explanation

Logistic → limited; Exponential → unlimited; Expanding pyramid → pre-rep largest; Stable pyramid → pre-rep ≈ rep.

Which one of the following is NOT an advantage of inbreeding?

A. It decreases homozygosity. B. It exposes harmful recessive genes that are eliminated by selection. C. Elimination of less desirable genes and accumulation of superior genes takes place due to it. D. It decreases the productivity of inbred population, after continuous inbreeding.

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

Inbreeding INCREASES (not decreases) homozygosity — so statement (A) is factually wrong, hence not an advantage.

The flippers of the Penguins and Dolphins are the example of:

A. Divergent evolution B. Adaptive radiation C. Natural selection D. Convergent evolution

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

Different ancestors converging on the same flipper morphology to suit aquatic locomotion → convergent evolution (analogous organs).

Which one of the following factors will not affect the Hardy-Weinberg equilibrium?

A. Constant gene pool B. Genetic recombination C. Genetic drift D. Gene migration

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

"Constant gene pool" describes the equilibrium itself — it does not perturb it. The other three (recombination, drift, migration) are factors that can disturb H-W equilibrium.

Given below are two statements:

Statement I: Gause's competitive exclusion principle states that two closely related species competing for different resources cannot exist indefinitely.

Statement II: According to Gause's principle, during competition the inferior will be eliminated. This may be true if resources are limiting.

In the light of the above statements, choose the correct answer from the options given below:

A. Statement I is false but Statement II is true. B. Both Statement I and Statement II are true. C. Both Statement I and Statement II are false. D. Statement I is true but Statement II is false.

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

Both reflect Gause's competitive exclusion concept as stated in NCERT.

D. Paleozoic Era	IV. Mammals

Choose the correct answer from the options given below:

A. A-III, B-I, C-IV, D-II B. A-II, B-I, C-III, D-IV C. A-III, B-I, C-II, D-IV D. A-I, B-II, C-IV, D-III

Sweet potato and potato represent a certain type of evolution. Select the correct combination of terms to explain the evolution.

A. Analogy, convergent B. Homology, divergent C. Homology, convergent D. Analogy, divergent

You've reached today's free limit of 20 questions. Log in to keep practising for free.

Explanation

Sweet potato (modified root) and potato (modified stem) perform the same storage function from different origins — analogous structures arising by convergent evolution.
