Diversity in Living Organisms
3,829 Questions
The diversity in living organisms deals with the classification of life forms into various kingdoms and phyla. This topic covers specific traits of bacteria, animal body cavities, and structural adaptations for survival. These fundamentals are crucial for biology sections in medical entrance and state board exams.

Diversity in Living Organisms Questions
A
Correct answer
Explanation
Physical adaptations are structural features of an organism's body. The specific shape and arrangement of toes are physical traits that aid in survival.
B
Correct answer
Explanation
Nocturnal activity is a behavioral adaptation because it describes the timing of the animal's actions. It is a way of behaving to avoid predators or find prey.
A
Correct answer
Explanation
Migration is a behavioral adaptation because it is a complex action performed by the animal to survive changing seasons or food availability.
A
Correct answer
Explanation
Coloration and camouflage are physical adaptations because they are structural features of the animal's body that help it blend into its environment.
A
Correct answer
Explanation
Teeth are structural components of the body. Having specialized teeth for tearing meat is a classic example of a physical adaptation.
B
Correct answer
Explanation
Hibernation is a behavioral adaptation because it is a state of dormancy or a series of actions taken by the animal to survive the winter.
B
Correct answer
Explanation
Squirting ink is a defensive action performed by the squid. Since it is an activity rather than a structural body part, it is a behavioral adaptation.
A
Correct answer
Explanation
A tail is a physical body part. Using it for balance or movement is a function of that physical structure, making it a physical adaptation.

Bacteria
-
Cockroach
-
Sparrow
-
Mosquito
A
Correct answer
Explanation
Bacteria are single-celled organisms, making them unicellular. Cockroaches, sparrows, and mosquitoes are multicellular organisms.
-
they both are mulicellular
-
they are made of one or more cells
-
they have organs
-
they live in the jungle
B
Correct answer
Explanation
According to the cell theory, all living organisms are composed of one or more cells. This is the fundamental shared characteristic between a single-celled protist and a multicellular tigress.

-
highest unit
-
basic unit
-
light source
C
Correct answer
Explanation
Cell theory defines the cell as the basic structural and functional unit of all living organisms.
-
Prokaryotic
-
Eukaryotic
-
Amoebic
-
Phylogenic
A
Correct answer
Explanation
Prokaryotic cells are simple cells that lack a nucleus and membrane-bound organelles. They contain DNA and a cell membrane but are structurally less complex than eukaryotic cells.
A
Correct answer
Explanation
Vertebrates are characterized by a spinal column and a distinct head region, which includes paired sensory structures like eyes and ears. These are key developmental features of the subphylum.
B
Correct answer
Explanation
Mammals are endothermic, meaning they are capable of regulating their internal body temperature independently of the external environment. This is a defining characteristic of the class Mammalia.
-
Animalia
-
Eubacteria
-
Fungi
-
Plantae
A
Correct answer
Explanation
Humans are classified within the Kingdom Animalia, as they are multicellular, eukaryotic, heterotrophic organisms.
