Biology is the branch of science that studies life. It deals with living organisms such as plants, animals, and microorganisms. It also studies how these organisms grow, reproduce, and carry out life processes. Therefore, biology is known as the science of life forms and living processes.
2. The living world comprises:
Correct Answer: B
The living world includes a huge variety of organisms such as plants, animals, fungi, bacteria, and many microscopic life forms. These organisms differ in size, shape, structure, and habitat. Some are very large like elephants and trees, while others are extremely small like bacteria. Because of this wide variety, the living world is said to have amazing diversity.
3. Early man could easily perceive the difference between:
Correct Answer: B
Early humans could easily understand the difference between living and non-living things. Living organisms such as animals and plants show life processes like growth, movement, breathing, and reproduction. In contrast, inanimate matter like rocks, soil, and water do not show these characteristics. This clear difference helped early humans recognize what is living and what is non-living.
4. Early man deified some of the inanimate matter such as:
Correct Answer: A
Early humans considered some natural forces like wind, sea, and fire as divine or sacred. They believed these powerful elements had supernatural power and therefore worshipped them. Similarly, some animals and plants were also treated as sacred. This shows how early humans tried to understand nature through beliefs and reverence.
5. Why did early man deify some inanimate matter and living organisms?
Correct Answer: C
Early humans often worshipped powerful natural elements like wind, sea, and fire, as well as some animals and plants. These natural objects and living organisms appeared mysterious and powerful to them. They created feelings of awe, wonder, and sometimes fear. Because early humans did not fully understand natural phenomena, they believed these forces had divine powers and treated them as sacred.
6. The scientific description of living organisms, including humans, began:
Correct Answer: B
In the early stages of human civilization, people mainly observed nature and often worshipped natural objects. Systematic study and description of living organisms, including humans, started much later. As knowledge and scientific thinking developed, humans began to observe, classify, and describe plants, animals, and other organisms in a more organized and scientific way.
7. Societies with an anthropocentric view of biology showed:
Correct Answer: C
Anthropocentric view means thinking that humans are the most important part of nature and everything exists mainly for humans. Societies that focused only on humans did not study other living organisms deeply. Because of this narrow view, their understanding of plants, animals, and other life forms remained limited, which slowed the progress of biological knowledge.
8. Systematic and monumental description of life forms led to the development of:
Correct Answer: B
When scientists began to study and describe a large number of living organisms, it became necessary to organize them properly. This led to the development of systems for identification (recognizing organisms), nomenclature (giving scientific names), and classification (grouping organisms based on similarities and differences). These systems help scientists study and understand the diversity of life in an organized way.
9. The biggest spin off of systematic studies of organisms was the recognition of:
Correct Answer: B
Systematic studies of living organisms revealed that many organisms share similarities with each other. These similarities can be observed horizontally, meaning among organisms at the same level, and vertically, meaning across different levels of classification. This understanding helped scientists trace relationships among organisms and develop better systems of classification.
10. All present-day living organisms are related to:
Correct Answer: C
Biological studies show that all present-day living organisms share a common origin and are related to organisms that lived in the past. Through evolution, new species developed from earlier life forms over millions of years. This concept shows the continuity of life on Earth and explains how different organisms are connected through evolutionary relationships.
11. The realization that all present-day organisms are related to past organisms led to:
Correct Answer: B
Scientific understanding showed that all living organisms are connected through evolution and share a common ancestry. This realization made humans understand that they are only a part of the vast web of life on Earth. It humbled humanity and created awareness about the importance of protecting living organisms. As a result, many cultural and scientific movements started to conserve biodiversity and protect nature.
12. From whose perspective will animals and plants be described and classified in the following chapters?
Correct Answer: C
In biology, taxonomy is the branch that deals with the identification, naming, and classification of living organisms. A taxonomist studies organisms and groups them based on their similarities and differences. Therefore, in the following chapters, animals and plants are described and classified from a taxonomist’s perspective to understand their relationships and diversity.
