Variation & Genetics (Heredity)
Solution
The ability of an organism to live successfully in an environment is known as
A
resistance
B
competetion
C
succession
D
adaptation
medium Difficulty
Verified Correct Answer: Option D
Biological Concept & Syllabus Guide
Adaptation is a heritable trait that helps an organism survive and reproduce in its environment. Adaptations can be behavioral, morphological, or physiological. They can be the result of a gene mutation that improves an organism's ability to survive and reproduce. Over time, the mutation becomes more common as it passes to offspring.

Adaptation & Evolution
Solution
A green snake in green grass is able to escape notice from predators because of its
A
disruptive colouration
B
counter shading
C
warning colouration
D
cryptic colouration
medium Difficulty
Verified Correct Answer: Option D
Biological Concept & Syllabus Guide
Disruptive coloration is a camouflage technique that uses contrasting patterns to break up an animal's outline and make it harder to see.
Countershading is a type of camouflage where an animal's upper body is darker than its underside.
Warning coloration is a defense mechanism used by animals to warn predators that they are toxic, distasteful, or have other harmful qualities.
Cryptic colouration, also known as camouflage, is a defense mechanism that helps organisms hide their identity, location, and movement by blending in with their surroundings. It's a common form of visual camouflage that uses color patterns to make it harder for predators to see the organism.

Nutrition in Plants & Animals (Photosynthesis & Food Substances)
Solution
For heterotrophic organisms, competition is least caused by the inadequacy of
A
mates
B
space
C
light
D
nutrients
medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
Among autotrophs, Light is the major cause of competition because they need sunlight to manufacture their food and survive unlike heterotrophs. Hence,competition is least caused by inadequacy of light.

Solution
Which of the following groups contains a non-supporting structure in animals?
A
Cartilage, bone and pseudopodia
B
Pellicle, chitin and bone
C
Humerus, ribs and cartilage
D
Femur, pellicle and chitin
medium Difficulty
Verified Correct Answer: Option B
Biological Concept & Syllabus Guide
The correct answer is 'pellicle, chitin, and bone'. In this option, the pellicle is a non-supporting structure in animals. The pellicle is a thin layer supporting the cell membrane in various protozoa. It provides protection but does not provide structural support like bones or cartilage. Chitin and bone, on the other hand, are supporting structures.
