1.
This biologist proposed that elephant shrews should be called sengis.
Correct Answer
C. Jonathan Kingdon
Explanation
Jonathan Kingdon is the correct answer because he is the biologist who proposed that elephant shrews should be called sengis. The other options, Sam Wright, Carl Leon, and David Bazz, are not relevant to this proposal and do not have any known association with the naming of elephant shrews.
2.
Elephant shrews can be found in?
Correct Answer
A. Namib Desert
Explanation
Elephant shrews can be found in the Namib Desert. The Namib Desert is a coastal desert located in southwestern Africa, primarily in Namibia but also extending into Angola and South Africa. It is known for its unique and diverse wildlife, including the elephant shrew. These small mammals have adapted to the harsh desert environment and can be found in the sandy dunes and rocky outcrops of the Namib Desert. They are well-suited to this habitat, using their long noses to probe for insects and their agile bodies to navigate the challenging terrain.
3.
Elephant shrews belong to the Class?
Correct Answer
B. Mammalia
Explanation
Elephant shrews belong to the Class Mammalia. This is because they are small, insectivorous mammals that share common characteristics with other mammals, such as having fur, giving birth to live young, and producing milk to feed their offspring. The Class Mammalia includes a wide range of animals, from elephants to bats to humans, and elephant shrews are a part of this diverse group.
4.
Their high-crowned cheek teeth have been compared to those of?
Correct Answer
C. Ungulates
Explanation
The high-crowned cheek teeth of the subject have been compared to those of ungulates. This suggests that the subject's cheek teeth share similarities with the teeth of hoofed mammals such as horses, cows, and deer. The comparison implies that the subject's teeth may have similar structural features or functions, such as being adapted for grinding and chewing tough plant material.
5.
Elephant shrews defend their home territory using?
Correct Answer
D. Scent glands
Explanation
Elephant shrews defend their home territory using scent glands. Scent glands are specialized glands that produce and release chemical compounds called pheromones. These pheromones are used by elephant shrews to mark their territory and communicate with other shrews. By leaving scent marks, they can establish boundaries and warn potential intruders to stay away. This behavior helps them maintain their territory and protect their resources, such as food and mates, from other shrews.
6.
Which of these is a species of elephant shrews?
Correct Answer
A. Rhynchocyon
Explanation
Rhynchocyon is a species of elephant shrews. Elephant shrews, also known as sengis, are small mammals that are native to Africa. They are characterized by their long noses, which resemble the trunks of elephants, and their small size. Rhynchocyon is a specific genus within the elephant shrew family, and it includes several different species. These animals are known for their agility and speed, as well as their unique adaptations for feeding and locomotion.
7.
As a predator, an elephant shrew eats one of these.
Correct Answer
A. Spiders
Explanation
Elephant shrews are known to be insectivores, and their diet primarily consists of insects. Among the options given, spiders are the only insects. Therefore, it can be inferred that as a predator, an elephant shrew would eat spiders.
8.
What does the elephant shrew use to find its prey?
Correct Answer
B. Nose
Explanation
The elephant shrew uses its nose to find its prey. The nose of the elephant shrew is long and flexible, allowing it to sniff out insects and other small creatures that it feeds on. This adaptation helps the elephant shrew locate its prey even in dense vegetation or underground. By using its sensitive nose, the elephant shrew can detect the scent of its prey and track it down for hunting.
9.
A distinct feature of the Elephantulus elephant shrew is?
Correct Answer
C. Dusky foot
Explanation
The distinct feature of the Elephantulus elephant shrew is its dusky foot. This means that its feet have a dark or shadowy appearance. This could be an adaptation to its environment, providing camouflage or protection. The dusky foot may help the shrew blend in with its surroundings or make it harder for predators to spot it. Additionally, the dusky foot could also aid in the shrew's movement, allowing it to navigate different terrains more effectively.
10.
Elephant shrews belong to the Superorder?
Correct Answer
A. Afrotheria
Explanation
Elephant shrews belong to the Superorder Afrotheria. Afrotheria is a diverse group of mammals that originated in Africa and includes elephants, manatees, hyraxes, and tenrecs, among others. This superorder is characterized by certain genetic and anatomical features that distinguish them from other mammalian groups. Elephant shrews, also known as sengis, are small insectivorous mammals that are found in Africa. They are part of the Afrotheria superorder due to their evolutionary history and genetic similarities with other members of this group.
