1.
What is the natural science that studies life and living organism?
Correct Answer
B. Biology
Explanation
Biology is the natural science that studies life and living organisms. It focuses on understanding the structure, function, growth, evolution, and distribution of living organisms. Biology encompasses various sub-disciplines such as botany, zoology, microbiology, and genetics, among others. It explores the different aspects of life, including the processes that occur within living organisms and their interactions with the environment. Through the study of biology, scientists gain insights into the complex and diverse nature of life on Earth.
2.
What is cell?
Correct Answer
D. Basic unit of life
Explanation
The correct answer is "Basic unit of life." A cell is the smallest structural and functional unit of an organism. It is capable of carrying out all the processes necessary for life, such as metabolism, reproduction, and responding to stimuli. Cells can exist as single-celled organisms or as part of a multicellular organism, where they work together to perform specific functions. Cells are composed of various organelles, such as the nucleus, mitochondria, and ribosomes, which carry out specific tasks within the cell.
3.
What is evolution?
Correct Answer
C. An engine propelling creation and extinction of species
Explanation
Evolution refers to the process of gradual development and change in living organisms over time. It involves the creation of new species through genetic variations and natural selection, as well as the extinction of existing species that are unable to adapt to their changing environment. This answer accurately describes evolution as an engine that drives both the creation and extinction of species, highlighting the dynamic nature of the evolutionary process.
4.
What is gene?
Correct Answer
D. Basic unit of hereditary
Explanation
The correct answer is "Basic unit of hereditary." A gene is a segment of DNA that contains the instructions for building and maintaining an organism. It is the basic unit of hereditary because genes are passed down from parents to offspring and determine the traits and characteristics of an individual. Genes play a crucial role in the transmission of genetic information and are responsible for the inheritance of traits such as eye color, height, and susceptibility to certain diseases.
5.
Which of the following is an open system?
Correct Answer
A. A living organism
Explanation
A living organism is considered an open system because it interacts with its environment, exchanging matter and energy with it. It takes in nutrients and oxygen, releases waste products, and maintains a constant internal environment through various physiological processes. This constant exchange with the environment allows living organisms to adapt and respond to changes in their surroundings, making them open systems. Non-living organisms, fossils, and non-fossils do not have the same level of interaction and exchange with their environment, thus they are not considered open systems.
6.
What is heomostatis?
Correct Answer
C. Maintaining a stable and vital condition
Explanation
Homeostasis refers to the body's ability to maintain a stable and vital condition. It involves various physiological processes that help regulate internal variables such as body temperature, blood pressure, pH levels, and glucose levels within a narrow range. This balance is crucial for the body to function optimally and ensure that cells, tissues, and organs can carry out their respective functions effectively. Homeostasis allows the body to adapt to changes in the external environment and maintain internal equilibrium, promoting overall health and well-being.
7.
Which of the following is a subdiscipline of biology
Correct Answer
D. Theoretical biology
Explanation
Theoretical biology is a subdiscipline of biology that focuses on the development and use of mathematical and computational models to understand biological systems. It involves the application of theoretical frameworks and principles to study biological phenomena, such as evolution, population dynamics, and ecological interactions. Theoretical biologists use mathematical equations, computer simulations, and statistical analyses to make predictions and gain insights into complex biological processes. This subdiscipline plays a crucial role in advancing our understanding of biological systems and has applications in various fields, including medicine, ecology, and genetics.
8.
What does the word 'Bios' means
Correct Answer
A. Life
Explanation
The word 'Bios' means life.
9.
What is the meaning of logia?
Correct Answer
C. Study
Explanation
Logia refers to the study of a particular subject or field. It is derived from the Greek word "logos" which means "study" or "discourse". Therefore, the correct answer for the meaning of logia is study.
10.
Who said the word"biologi" first?
Correct Answer
D. Carl Linnaeus
Explanation
Carl Linnaeus is credited with coining the word "biologi" (biology) in the modern sense. Linnaeus was a Swedish botanist and zoologist who developed the binomial nomenclature system for naming species. He is widely regarded as the father of modern taxonomy and made significant contributions to the field of biology. Therefore, it is logical to attribute the first use of the word "biologi" to Carl Linnaeus.
