Free Kingdom Animalia MCQs with Answers

821. The name animal is derived from what word?

• A. Aname
• B. Anima
• C. Anemia
• D. None of these

Explanation: Yes, the word animal is derived from the Latin word anima, which means "breath, spirit, life". The word animal was first used in English in the 14th century, and it originally referred to any living creature. However, the meaning of the word has narrowed over time, and it now specifically refers to a living organism that is not a plant.The connection between the words animal and anima is that both words refer to the life force that animates living creatures. In Latin, the word anima was also used to refer to the soul, and this meaning is still preserved in some languages, such as French, where the word animal is also used to refer to the soul.

822. Ascarisis characterized by which of the following?

• A. Presence of true coelom and metamerism
• B. Absence of true coelom and metamerism
• C. Presence of true coelom but the absence of metamerism
• D. Absence of true coelom but thepresence of metamerism

Explanation: Ascaris does not have a true coelom. Ascaris is an example of a pseudocoelomate organism. It possesses a pseudocoelom, which is a body cavity that is not entirely lined by mesoderm. This is in contrast to true coelomates, where the body cavity is completely lined by mesoderm.

827. The social organization of howling monkeys was studied by:

• A. Allen
• B. Thorpe
• C. Schjeldeup ebbe
• D. Carpenter

Explanation: The social organization of howling monkeys has been studied by several researchers. Among the options you provided, Allen, Thorpe, Schjelderup-Ebbe, and Carpenter, only one of them is directly associated with studying howling monkeys' social organization. The correct answer is Carpenter. Allen: It is unclear which specific Allen you are referring to, as there have been many researchers named Allen in various fields. Without further information, it is difficult to determine if any of them have specifically studied howling monkeys' social organization. Thorpe: Again, without more context, it is challenging to identify which Thorpe you are referring to. There have been multiple researchers with the last name Thorpe. However, it is worth mentioning that the name Thorpe is not commonly associated with studies on howling monkeys' social organization. Schjelderup-Ebbe: Konrad Lorenz is well-known for his work on ethology and animal behavior, including his studies on the pecking order in chickens, which introduced the concept of "dominance hierarchy" and "pecking order." However, Schjelderup-Ebbe is not typically associated with howling monkeys' social organization research. It's possible there may be some connection or reference I am not aware of, but it is not a commonly recognized association. Carpenter: Robert Carpenter is a primatologist known for his extensive research on howling monkeys' social organization. His work has focused on studying the behavior, ecology, and social dynamics of howling monkeys in their natural habitats. Carpenter's research has contributed significantly to our understanding of howling monkey social systems, including their vocalizations, group composition, and mating strategies. In conclusion, among the options provided, Carpenter is the researcher most closely associated with studying the social organization of howling monkeys.

828. Diseases in living organisms which are caused by parasites are called:

• A. Disinfestations
• B. Antisepsis
• C. Infections
• D. Infestations

Explanation: FACT Diseases in living organisms that are caused by parasites are called infestations.

829. This group of animals have three bones in the ear.

• A. Reptiles
• B. Mammals
• C. Both reptiles and mammals
• D. Birds and mammals

Explanation: Option A: Reptiles generally do not have three bones in the ear. Instead, reptiles typically have a single bone in their middle ear called the stapes or columella. This bone is responsible for transmitting sound vibrations from the eardrum to the inner ear.Option B: Mammals have three bones in the ear. These three bones, known as the ossicles, are located in the middle ear. They are named the malleus (hammer), incus (anvil), and stapes (stirrup). The ossicles transmit sound vibrations from the eardrum to the inner ear, amplifying and transmitting sound waves for auditory perception.Option C: Both reptiles and mammals: This option is incorrect. Reptiles typically have a single bone (stapes or columella) in the middle ear, while mammals have the three ossicles (malleus, incus, and stapes).Option D: Birds and mammals: This option is correct. Both birds and mammals have three bones in the ear. In birds, the three bones are called the columella, incus, and stapes. These bones play a similar role to the mammalian ossicles, transmitting sound vibrations from the eardrum to the inner ear for auditory processing.

830. What is the size range of porifera?

• A. Few centimeter wide to more than one meter tall.
• B. Few decimeter wide to more than one meter tall.
• C. One meter wide to more than millimeter tall.
• D. Few millimeter wide to more than one meter tall.

Explanation: Most Porifera are only a few centimeters in size, but some urn-shaped or shapeless ones are less than a centimeter (0.4 inches); others, shaped like vases, tubes, or branches, maybe one to two meters (3.3-6.6 feet) tall, and broad rounded masses may be one to two meters in diameter.
