Animal Biology Quiz: Everything You Have Learned So Far! - Quiz

Animal Biology is the study of the chemical and physical structure and behavior of animals with reference to their molecular and cellular systems, anatomy, and physiology. The concept of animal biology as a single coherent field of study started after the zoological sciences which emerged from natural history as far back as the biological works of Aristotle. Are you an animal biologist? Or just a lover of animals? Can you ace this quiz for the love of animal sake? Give it a try.

Questions and Answers

1.

What is the dentition of animals with two successions of teeth called?
- A.
  
  Duodent
- B.
  
  Homodent
- C.
  
  Heterodent
- D.
  
  Diphyodont
Correct Answer
D. DipHyodont

Explanation
Diphyodont refers to the dentition of animals that have two successions of teeth. This means that they have two sets of teeth throughout their lifetime, with the first set being deciduous or milk teeth, and the second set being permanent teeth. This is a common characteristic in mammals, including humans, where they have baby teeth that are eventually replaced by adult teeth.

Which of these reproduces by binary fission?
- A.
  
  Planarians
- B.
  
  Moth
- C.
  
  Fishes
- D.
  
  Mollusc
Correct Answer
A. Planarians

Explanation
Planarians reproduce by binary fission, a form of asexual reproduction in which a single organism splits into two identical daughter organisms. This process involves the division of the parent organism's body into two halves, each of which then regenerates the missing parts to form a complete individual. Planarians are flatworms that have a remarkable ability to regenerate lost body parts, making them capable of undergoing binary fission and producing offspring without the need for a mate.

3.

Which of these is a form of asexual reproduction that results from the outgrowth of a part of the body leading to a separation from the original organism and the formation of two individuals?
- A.
  
  Fusion
- B.
  
  Fission
- C.
  
  Budding
- D.
  
  Fragmentation
Correct Answer
C. Budding

Explanation
Budding is a form of asexual reproduction where a new organism develops as an outgrowth or bud on the parent organism. The bud eventually separates from the parent and becomes an independent individual. This process allows for the formation of two individuals from a single parent organism.

Which group of animal take in food and get rid of waste with their mouth?
- A.
  
  Coelentrates
- B.
  
  Planarians
- C.
  
  Anthropods
- D.
  
  Chordata
Correct Answer
A. Coelentrates

Explanation
Coelenterates are a group of animals that take in food and get rid of waste through their mouth. They have a central cavity called the gastrovascular cavity that functions as both a digestive and circulatory system. Food particles are ingested through the mouth and digested within this cavity. Waste materials are then expelled through the same opening. This method of feeding and waste elimination is characteristic of coelenterates such as jellyfish and sea anemones.

5.

Which of these gives birth by Parthenogenesis?
- A.
  
  Yeast
- B.
  
  Bees
- C.
  
  Planarians
- D.
  
  Rats
Correct Answer
B. Bees

Explanation
Bees give birth by parthenogenesis, which is a form of asexual reproduction in which an unfertilized egg develops into an individual without the need for fertilization by a male gamete. In bees, the unfertilized eggs develop into drones, which are male bees. This process allows bees to reproduce without the need for mating, although it is not the primary method of reproduction for bees.

What does "Sapro" mean?
- A.
  
  Feeders
- B.
  
  Rotten
- C.
  
  Crawling
- D.
  
  Parent
Correct Answer
B. Rotten

Explanation
The term "Sapro" is derived from the Greek word "sapros" which means "rotten" or "decaying". Therefore, "Sapro" means "rotten".

7.

What is mode of nutrition in which organisms eat solid food?
- A.
  
  Holozoic
- B.
  
  Saprophytic
- C.
  
  Parasitic
- D.
  
  Cannibalism
Correct Answer
A. Holozoic

Explanation
Holozoic is the correct answer because it refers to the mode of nutrition in which organisms consume solid food. This type of nutrition involves the ingestion and digestion of large food particles, which are then broken down and absorbed by the organism. Holozoic nutrition is commonly seen in animals, including humans, who consume solid food for energy and nutrients.

8.

Which of these is a short term interaction between two organisms?
- A.
  
  Mutuality
- B.
  
  Symbiosis
- C.
  
  Parasitism
- D.
  
  Predation
Correct Answer
D. Predation

Explanation
Predation is a short term interaction between two organisms where one organism, the predator, hunts, kills, and consumes the other organism, known as the prey. This interaction is typically brief and ends with the predator obtaining nutrients from the prey. Unlike symbiosis or mutuality, which involve long-term relationships, predation is a one-sided interaction that benefits the predator while harming or killing the prey. Parasitism, on the other hand, is also a long-term interaction where one organism, the parasite, benefits at the expense of the host organism.

What is the distinguishing feature of birds to other animals?
- A.
  
  Laying of eggs
- B.
  
  Scaly feet
- C.
  
  Feathers
- D.
  
  Warm blood
Correct Answer
C. Feathers

Explanation
Birds are distinguished from other animals by their feathers. Feathers are unique to birds and serve multiple purposes such as insulation, flight, and display. Feathers provide birds with the ability to fly, which is a characteristic not found in most other animals. Additionally, feathers help birds regulate their body temperature and protect their skin. While other animals may lay eggs, have scaly feet, or be warm-blooded, feathers are the defining feature that sets birds apart from other creatures.

What type of dentition of animals in which the teeth are continuously discarded and replaced?
- A.
  
  Cast dentition
- B.
  
  Polyphyodont
- C.
  
  Monophyodont
- D.
  
  Diphyodont
Correct Answer
B. PolypHyodont

Explanation
Polyphyodont dentition refers to the type of dentition in which the teeth are continuously discarded and replaced. This means that as the old teeth fall out or wear down, new teeth grow in to replace them. This type of dentition is commonly seen in animals such as sharks and reptiles, allowing them to constantly have a fresh set of teeth for feeding and survival.
