About This Quiz

Animals by their constant interaction have been a key player in the ecosystem for a very long time and performing an essential role in the lives of other organisms, whether from the same kingdom or not. For instance, carbon dioxide that the animals breathe out is what trees breath in, and oxygen when breath out is in turn taken in. See moreAnimal Biology has helped in understanding these interactions, with the work starting with Galen and Aristotle. What else do you know about Animal Biology? Try this quiz.

2.

Which of the following studies the mechanical, physical, and biochemical processes of living organisms by attempting to understand how all of the structures function as a whole?
- Physiology
- Enthology
- Entomology
- Anthropology
Correct Answer

A. Physiology

Explanation

Physiology is the study of the mechanical, physical, and biochemical processes of living organisms. It focuses on understanding how all the structures in an organism function together as a whole. This field of study explores various aspects of living organisms, including their organ systems, cells, and molecules, to gain insights into their functions and mechanisms. By studying physiology, scientists can better understand the complex processes that occur within living organisms and how they contribute to overall health and functioning.

Which of these is an hermaphrodite?
- Amoeba
- Cats
- Snail
- Fishes
Correct Answer

A. Snail

Explanation

Snails are hermaphrodites, meaning they have both male and female reproductive organs. This allows them to reproduce with any other snail they come across. They can both produce and receive sperm during mating, increasing their chances of successful reproduction. This adaptation is advantageous for snails as it ensures the availability of potential mates and increases their reproductive success.

Which of these is coelentrate?
- Jelly fish
- Rodents
- Amoeba
- Pisces
Correct Answer

A. Jelly fish

Explanation

Jellyfish is a coelenterate because it belongs to the phylum Cnidaria, which includes organisms with specialized stinging cells called cnidocytes. Coelenterates are characterized by their radial symmetry, tentacles, and a simple body plan with a central cavity. Jellyfish have a gelatinous body, tentacles with stinging cells, and a central cavity for digestion. Rodents, Amoeba, and Pisces (fish) do not belong to the phylum Cnidaria and therefore are not coelenterates.

According to Carl Linnaeus classification of living organisms, how many levels of classifications are there?
- 3
- 5
- 7
- 9
Correct Answer

A. 7

Explanation

Carl Linnaeus' classification system, also known as the Linnaean system, consists of seven levels of classification. These levels, in hierarchical order, are kingdom, phylum, class, order, family, genus, and species. Each level represents a different level of similarity and difference among organisms, allowing for a systematic organization and categorization of living organisms. This system is still widely used in modern taxonomy and provides a standardized way to classify and study the diversity of life on Earth.

Which of these animals is in the phylum-chordata?
- Snails
- Worms
- Dogs
- Ants
Correct Answer

A. Dogs

Explanation

Dogs are in the phylum Chordata because they possess a notochord, which is a flexible rod-like structure that runs along the length of their body. This notochord is present during their embryonic stage and eventually develops into a spinal column or backbone. The phylum Chordata includes animals that have a notochord at some stage in their life cycle, such as mammals, birds, reptiles, and fish. Snails, worms, and ants do not belong to the phylum Chordata as they do not possess a notochord.

What is another name for deciduous teeth?
- Canines
- Baby Teeth
- Meat teeth
- Molars
Correct Answer

A. Baby Teeth

Explanation

Deciduous teeth are also commonly known as baby teeth. These are the first set of teeth that develop in humans and are eventually replaced by permanent teeth. The term "baby teeth" is used to describe these teeth because they are present during infancy and early childhood. Canines, molars, and meat teeth are types of teeth that can be found in both the deciduous and permanent dentition, but they do not specifically refer to deciduous teeth.

When reproducing how many times does a lion copulates within 24hours?
- Twice
- 25
- Once
- 50
Correct Answer

A. 50

Explanation

The given answer, 50, suggests that a lion copulates 50 times within 24 hours. However, this answer is incorrect. Lions do not copulate 50 times within 24 hours. Lions are known for their promiscuous mating behavior, where a male lion may mate multiple times with a female during her estrus period, which lasts for a few days. However, it is highly unlikely for a lion to copulate 50 times within just 24 hours.
