What is a long-term relationship between organisms called?
Correct Answer
B. Symbiosis
Explanation
A long-term relationship between organisms is called symbiosis. Symbiosis refers to a close and prolonged association between two different species, where both organisms benefit from the relationship. This can include mutualistic relationships, where both organisms benefit, as well as parasitic or commensal relationships, where one organism benefits at the expense of the other or without affecting the other, respectively. Symbiosis is a fundamental concept in ecology and plays a crucial role in shaping ecosystems and the interactions between different species.

What is the life span of a male lion?
Correct Answer
B. 10-15years
Explanation
Male lions typically have a lifespan of 10-15 years. This is shorter compared to female lions because male lions often face more challenges and dangers in their lives. They have to defend their territory, fight off rival males, and protect their pride. These factors, along with the physical toll of these activities, can contribute to a shorter lifespan for male lions.
3.
How many types of teeth are there?
Correct Answer
C. 4
Explanation
There are four types of teeth: incisors, canines, premolars, and molars. Incisors are the sharp, flat teeth at the front of the mouth used for cutting food. Canines are the pointed teeth next to the incisors, used for tearing food. Premolars are located behind the canines and are used for grinding and crushing food. Molars are the back teeth used for chewing and grinding food.
4.
What is the term given to the study of animals?
Correct Answer
D. Zoology
Explanation
Zoology is the correct answer because it is the scientific study of animals. It involves the study of their behavior, anatomy, physiology, classification, and distribution. Zoologists study animals in both their natural habitats and in captivity, and they contribute to our understanding of animal evolution, ecology, and conservation.
5.
What is the term given to the study of insects?
Correct Answer
A. Entomology
Explanation
Entomology is the correct answer because it is the scientific study of insects. This field of study involves examining the life cycle, behavior, classification, and ecology of insects. It also involves studying their interactions with other organisms and their impact on the environment. Anthropology is the study of human societies and cultures, not insects. Insectolography is not a recognized term, and Zoology is the study of animals in general, not specifically insects.
6.
Which of these is an exoskeleton?
Correct Answer
C. Spider
Explanation
An exoskeleton is a hard, external covering that provides support and protection to the body. In this context, the correct answer is spider because spiders have an exoskeleton made of chitin, which covers their entire body and provides structural support. Snails, birds, and worms do not have an exoskeleton; instead, they have internal skeletons or shells.
7.
Which of these modes of nutrition harms the host?
Correct Answer
A. Parasitic
Explanation
Parasitic mode of nutrition harms the host because parasites rely on living organisms (hosts) for their survival and obtain nutrients from them, often causing harm or damage to the host in the process. Parasites can cause diseases, weaken the host's immune system, and disrupt normal bodily functions. They may feed on the host's tissues, blood, or other bodily fluids, leading to various health problems and potentially even death.
8.
What is the main bone in the upper jaw of a dinosaur?
Correct Answer
D. Maxilla
Explanation
The main bone in the upper jaw of a dinosaur is called the maxilla. The maxilla is a paired bone that forms the upper jaw and holds the teeth in place. It is an important bone for feeding and is responsible for the attachment of various muscles involved in chewing and biting. The maxilla also plays a role in the overall structure and support of the dinosaur's skull.
9.
Which of these animals is a saproph?
Correct Answer
B. Vulture
Explanation
A saproph is an organism that feeds on dead or decaying organic matter. Vultures are known to be scavengers, feeding primarily on carrion or dead animals. They play a crucial role in the ecosystem by cleaning up carcasses, preventing the spread of diseases. Lions, man, and turkeys do not primarily feed on dead or decaying organic matter, making vultures the only correct answer in this context.
10.
Which of these is not in the cat family?
Correct Answer
C. Rhino
Explanation
Rhino is not in the cat family because it belongs to a different family called Rhinocerotidae. The cat family, scientifically known as Felidae, includes animals such as leopards, mountain lions, and tigers. Rhinos, on the other hand, are large herbivorous mammals that belong to the family Rhinocerotidae. They have distinct features and characteristics that differentiate them from cats, such as their horned snouts and thick skin.
