- 1.
Which of the following characteristic is not unique to chordates?
- A.
A fully developed notochord
- B.
Body cavity
- C.
Spinal chord
- D.
A three chambered heart
Correct Answer
B. Body cavityExplanation
A body cavity is not unique to chordates. Many other animal groups, such as arthropods and mollusks, also have a body cavity. A body cavity is a fluid-filled space between the body wall and the internal organs, providing protection and allowing for internal movement. While chordates have a body cavity, it is not a characteristic exclusive to them.Rate this question:

Approximately, how many species of vertebrates are present in the world?
- A.
60,000
- B.
80,000
- C.
123,000
- D.
500,000
Correct Answer
A. 60,000Explanation
There are approximately 60,000 species of vertebrates present in the world.Rate this question:

What is the preferred mode of reproduction of vertebrates?
- A.
Budding
- B.
Vegetative reproduction
- C.
Sexual reproduction
- D.
Spore formation
Correct Answer
C. Sexual reproductionExplanation
Sexual reproduction is the preferred mode of reproduction in vertebrates because it leads to genetic variation and diversity in offspring. This is important for the survival and adaptation of species in changing environments. Sexual reproduction involves the fusion of gametes, usually from two parents, resulting in offspring that inherit a combination of genetic traits from both parents. This genetic diversity increases the chances of offspring being able to adapt to different environmental conditions and enhances the overall fitness of the population.Rate this question:

The hollow nerve chord located is located on which side of the body?
- A.
Dorsal
- B.
Ventral
- C.
Anterior
- D.
Posterior
Correct Answer
A. DorsalExplanation
The correct answer is Dorsal. The hollow nerve chord is located on the dorsal side of the body. The term "dorsal" refers to the back or upper side of an organism. In many animals, including humans, the spinal cord is part of the dorsal nerve chord. This chord runs along the back of the body, protecting and transmitting nerve signals.Rate this question:

What are Urochordates?
- A.
Vertebrates
- B.
Reptiles
- C.
Invertebrate chordates
- D.
None of the above
Correct Answer
C. Invertebrate chordatesExplanation
Urochordates are a type of invertebrate chordates. This means that they are animals that possess a notochord, which is a flexible rod-like structure that provides support, but do not have a backbone or vertebral column. Urochordates include organisms such as tunicates or sea squirts, which are filter-feeding marine animals. They are considered to be the closest living relatives of vertebrates, but they themselves are not vertebrates. Therefore, the correct answer is "Invertebrate chordates".Rate this question:

An organism that has a dorsal, hollow nerve chord present at some point in it's life cycle is known as what?
- A.
Porifera
- B.
Mammal
- C.
Chordate
- D.
Archae
Correct Answer
C. ChordateExplanation
An organism that has a dorsal, hollow nerve chord present at some point in its life cycle is known as a chordate. This characteristic is unique to chordates and distinguishes them from other organisms. Porifera refers to sponges, which do not have a nerve chord. Mammals are a specific group of chordates, but not all chordates are mammals. Archae is a domain of single-celled microorganisms and is not related to chordates.Rate this question:

- 7.
Which of the following is among the characteristics of vertebrates?
- A.
Presence of pharyngeal slits
- B.
Presence of notochord
- C.
Presence of a dorsal hollow nerve cord
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
All of the characteristics mentioned in the options - presence of pharyngeal slits, presence of notochord, and presence of a dorsal hollow nerve cord - are indeed characteristics of vertebrates. Vertebrates, such as fish, amphibians, reptiles, birds, and mammals, possess all of these features during some stage of their life cycle. The pharyngeal slits are present in the throat region and are involved in respiration and feeding. The notochord is a flexible rod-like structure that provides support and serves as a precursor to the backbone. The dorsal hollow nerve cord runs along the back and eventually develops into the spinal cord.Rate this question:

Which of the following animals belongs to the phylum Chordata?
- A.
Salamanders
- B.
Sharks
- C.
Bears
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
All of the listed animals belong to the phylum Chordata. This phylum includes a diverse range of animals characterized by the presence of a notochord, a hollow dorsal nerve cord, pharyngeal slits, and a post-anal tail at some stage in their development. Salamanders, sharks, and bears all exhibit these characteristics, placing them within the phylum Chordata.Rate this question:

Which of the following animal belongs to the phylum Vertebrata?
- A.
Agnatha (Jawless Fish)
- B.
Birds
- C.
Osteichthyes
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
All of the options listed in the question belong to the phylum Vertebrata. Agnatha refers to jawless fish, which are vertebrates. Birds are also vertebrates, as they possess a vertebral column. Osteichthyes refers to bony fish, which are also vertebrates. Therefore, all of the options mentioned in the question belong to the phylum Vertebrata.Rate this question:

Which of the following animals have an aquatic gill-breathing larval stage that is (typically) by a terrestrial lung-breathing adult stage?
- A.
Mammals
- B.
Amphibians
- C.
Birds
- D.
Fishes
Correct Answer
B. AmpHibiansExplanation
Amphibians have an aquatic gill-breathing larval stage, usually in the form of tadpoles, which live in water and breathe through gills. As they mature, they undergo metamorphosis and develop lungs, allowing them to transition to a terrestrial lung-breathing adult stage. This is a defining characteristic of amphibians, as they are able to live both in water and on land throughout their life cycle.Rate this question:
