- B.
Mode of nutrition
- C.
Structure of ceil wall
- D.
Asexual reproduction
Correct Answer
A. Structure of nucleusExplanation
The correct answer is "structure of nucleus." In the five kingdom system, the main basis of classification is the structure of the nucleus. The nucleus is a membrane-bound organelle that contains the genetic material of the cell. The structure of the nucleus can vary among different organisms and is used to categorize them into different kingdoms. This classification is important as it helps scientists understand the evolutionary relationships and characteristics of different organisms.Rate this question:

Lateral symmetry is accompanied by
- A.
Neoteny
- B.
Metamerism
- C.
Metamorphosis
- D.
Cephalization
Correct Answer
D. CephalizationExplanation
Cephalization refers to the evolutionary process where organisms develop a distinct head region with sensory organs and a centralized nervous system. Lateral symmetry, on the other hand, is the arrangement of body parts in a way that they are mirrored on both sides of a central axis. The correct answer, cephalization, is the most logical choice as it is the only option that is related to the development of a distinct head region, which is not directly associated with lateral symmetry. Neoteny refers to the retention of juvenile characteristics in adult organisms, metamorphosis is the process of transformation from one stage to another, and metamerism refers to the repetition of body segments.Rate this question:

Schizocoelomates and enterocoelomates are
- A.
Acoelomates
- B.
Invertebrates
- C.
True coelomates
- D.
Endoderms only
Correct Answer
C. True coelomatesExplanation
Schizocoelomates and enterocoelomates are both examples of true coelomates. A true coelom is a body cavity that is completely lined by mesoderm tissue. In schizocoelomates, the coelom forms by splitting of the mesoderm, while in enterocoelomates, it forms as outpocketings of the archenteron. Both of these groups have a true coelom, distinguishing them from acoelomates, which lack a body cavity, and from endoderms only, which would only have an endoderm-lined cavity.Rate this question:

The body cavity of coelomates is lined by
- A.
Mesoderm
- B.
Ectoderm
- C.
Endoderm
- D.
Protoplasm
Correct Answer
A. MesodermExplanation
In coelomates, the body cavity is lined by mesoderm. Mesoderm is one of the three primary germ layers in the developing embryo, and it gives rise to various structures including muscles, bones, connective tissues, and the lining of the body cavity. The mesoderm forms a protective layer around the internal organs, providing support and allowing for movement. This lining helps to separate the organs from the outer body wall and other structures, maintaining their position and preventing friction between them.Rate this question:

The character that differentiates chordate from non-chordata is
- A.
Dorsal tubular nerve cord
- B.
Alimentary canal
- C.
Bilateral symmetry
- D.
Both (A) and (B)
Correct Answer
A. Dorsal tubular nerve cordExplanation
The character that differentiates chordates from non-chordates is the presence of a dorsal tubular nerve cord. This nerve cord is located along the dorsal (back) side of the body and serves as the main pathway for transmitting nerve impulses. Non-chordates, on the other hand, do not possess this specific feature. The presence of a dorsal tubular nerve cord is a defining characteristic of chordates and sets them apart from other animals.Rate this question:

Which one of the following statements about certain given animals is correct?
- A.
Flat worms (Platyhelminthes) are coelomates
- B.
Round worms (Aschelminthes) are pseudocoelomates
- C.
Molluscs are acoelomates
- D.
Insects are pseudocoelomates
Correct Answer
B. Round worms (Aschelminthes) are pseudocoelomatesExplanation
Round worms (Aschelminthes) are pseudocoelomates. Pseudocoelomates have a body cavity called a pseudocoelom, which is not completely lined by mesoderm. Round worms have a pseudocoelom, which is a fluid-filled body cavity that is not fully lined by mesoderm. This distinguishes them from coelomates like flat worms (Platyhelminthes), which have a true coelom, a body cavity completely lined by mesoderm. Molluscs are acoelomates, meaning they lack a body cavity, and insects are also pseudocoelomates, like round worms.Rate this question:

Uricotelic mode of passing out nitrogenous wastes is found in
- A.
Reptiles and Birds
- B.
Birds and Annelids
- C.
Amphibians and Reptiles
- D.
Insects and Amphibians
Correct Answer
A. Reptiles and BirdsExplanation
The uricotelic mode of passing out nitrogenous wastes refers to the excretion of uric acid as the main nitrogenous waste product. This mode of excretion is found in reptiles and birds. Uric acid is a semi-solid waste that requires less water for its excretion, making it suitable for organisms that have limited access to water, such as reptiles and birds. This mode of excretion helps in conserving water and reducing the risk of dehydration in these animals.Rate this question:
