1. The study of improvement of the human race by improving the environment is known as?
- Euphenics
- Etiology
- Euthenics
- Eugenics
Show Answer
Answer: Euthenics
Euthenics is the scientific study of improving the human condition by enhancing environmental factors. Unlike eugenics, which focuses on genetics, euthenics seeks to optimize the quality of life through improvements in living conditions, education, nutrition, and overall environmental factors.
2. Dendrochronology’ is the study of the age of which of the following?
- Fungi
- Shrubs
- Woody Plants
- All of the above
Show Answer
Answer: Woody Plants
Dendrochronology is a method used to estimate the age of woody plants by analyzing the patterns of tree rings. Each ring represents a year of growth, allowing scientists to reconstruct a timeline of environmental conditions and events, making it a valuable tool in ecology, archaeology, and climate science.

5. What is the correct meaning of Phyllotaxy?
- The manner the leaves fall from the branches
- The anatomy of leaves in angiosperms
- Classification of plants as per the leaves’ structure
- The manner of arrangement of leaves in stem or branch
Show Answer
Answer: The manner of arrangement of leaves in stem or branch
Phyllotaxy pertains to the arrangement of leaves on a plant stem or branch. It describes the specific geometric pattern formed by the positioning of leaves, providing insights into plant morphology and growth. Phyllotaxy is essential for botanists and plant scientists studying the structural aspects of plants, as it influences light absorption and overall plant development.
6. What is correct about biocenosis?
- Study of the parts of an ecosystem with specific species
- A kind of abnormality related to organisms living in a particular habitat
- The study of energy transformations in living systems
- Community of organisms occupying an area
Show Answer
Answer: Community of organisms occupying an area
Biocenosis refers to the interacting community of organisms living together in a specific habitat or biotope. This ecological concept emphasizes the relationships and interactions between different species within a defined geographical area. Understanding biocenosis is crucial for ecological studies, conservation efforts, and maintaining the balance of ecosystems.
7. Lepidopterology is a branch of biology that deals with the study of which animals?
- Lipids and Fats
- Moths & Butterflies
- Ferns
- Animals in stagnant waters
Show Answer
Answer: Moths & Butterflies
Lepidopterology is the scientific study of moths and the three superfamilies of butterflies. Researchers in this field focus on gaining a comprehensive understanding of these winged insects, exploring their biology, behavior, taxonomy, and ecological roles. The study of lepidopterology contributes to broader knowledge about insect biodiversity and ecosystem dynamics.
8. In which of the following branches of science is the study of functions, characteristics, and phenomena observed in the living world and the application of this knowledge to the world of machines studied?
- Bionomy
- Bionics
- Biometry
- None of the above
Show Answer
Answer: Bionics
Bionics involves the application of biological methods in conjunction with engineering principles to machines. This interdisciplinary field integrates mechanics, electronics, and components inspired by biological organisms to create innovative technologies. Bionics seeks to replicate the efficiency and functionalities observed in nature, leading to groundbreaking developments in various industries.
9. Gnathology” is the study of which among the following?
- Masticatory System
- Tongue
- Teeth
- Jaws
Show Answer
Answer: Masticatory System
Gnathology is the scientific study of the masticatory system, which encompasses the physiology of chewing, functional disturbances related to the jaw, and the treatment of these issues. By understanding the intricacies of how organisms chew, researchers in this field contribute to advancements in oral health and treatments for jaw-related disorders.
10. Herpetology is the branch of science that deals with the study of which of the following?
Options:
- Snakes
- Amphibians and Reptiles
- Fishes
- Insects
Show Answer
Answer: Amphibians and Reptiles
Herpetology is a branch of zoology focusing on amphibians (like frogs, toads, salamanders) and reptiles (such as snakes, lizards, turtles). It explores their biology, behavior, ecology, and conservation. Herpetologists study the fascinating life cycles of amphibians and the adaptations that help reptiles survive. Fieldwork and research contribute to understanding biodiversity and aiding conservation efforts for these unique creatures facing various threats in their habitats.
