1.
A stone is non living thing.
Correct Answer
A. True
Explanation
The given statement is true because a stone is a non-living thing. Non-living things do not possess characteristics of life such as growth, reproduction, metabolism, or response to stimuli. A stone is an inanimate object made up of minerals and does not possess any form of life.
2.
Water is man-made.
Correct Answer
B. False
Explanation
Water is not man-made. It is a naturally occurring compound composed of two hydrogen atoms bonded to one oxygen atom. While humans can manipulate and treat water for various purposes, such as purification or desalination, they cannot create water from scratch. Water exists in abundance in nature, including in oceans, lakes, rivers, and even in the atmosphere.
3.
A tree cannot grow.
Correct Answer
B. False
Explanation
The statement "A tree cannot grow" is false. Trees are living organisms that have the ability to grow and develop over time. They obtain nutrients from the soil, water from the environment, and energy from sunlight through photosynthesis, which enables them to increase in size and height. Trees also produce new branches, leaves, and roots as they grow. Therefore, it is incorrect to say that a tree cannot grow.
4.
Plants and animals are non living things.
Correct Answer
B. False
Explanation
The statement "Plants and animals are non living things" is incorrect. Plants and animals are actually living things as they possess characteristics such as growth, reproduction, and response to stimuli. They are part of the living organisms in the natural world.
5.
Reproduction is the characteristics of living things.
Correct Answer
A. True
Explanation
Reproduction is indeed one of the characteristics of living things. It refers to the ability of living organisms to produce offspring or create new individuals of the same species. This process ensures the continuation of the species over time and is essential for the survival and evolution of living organisms.
6.
Cats and dogs are non living things.
Correct Answer
B. False
Explanation
The statement is false because cats and dogs are living organisms. They are both examples of animals and belong to the kingdom Animalia. They possess the characteristics of living things, such as the ability to move, reproduce, and respond to stimuli.
7.
A bag is a non-living thing.
Correct Answer
A. True
Explanation
The statement is true because a bag is an inanimate object and does not possess the characteristics of a living thing. It does not have the ability to grow, reproduce, or respond to stimuli. A bag is typically made of materials like fabric or plastic and is used for carrying or storing items, which are tasks performed by humans or animals. Therefore, it can be concluded that a bag is indeed a non-living thing.
8.
Air is a living thing.
Correct Answer
B. False
Explanation
Air is not a living thing because it does not have the characteristics of living organisms. Living things are made up of cells, can grow and reproduce, and respond to stimuli. While air is essential for the survival of living organisms, it is not alive itself. It consists of a mixture of gases such as nitrogen, oxygen, carbon dioxide, and others, but it does not possess the ability to exhibit life processes.
9.
Weather and climate are non-living things.
Correct Answer
A. True
Explanation
Weather and climate are non-living things because they are not biological entities. Weather refers to the day-to-day conditions of the atmosphere, including temperature, precipitation, and wind, while climate refers to the long-term patterns and trends of weather in a specific region. Both weather and climate are the result of physical processes and interactions between the atmosphere, land, and oceans, rather than being living organisms. Therefore, it is correct to say that weather and climate are non-living things.
10.
Air is important for living things.
Correct Answer
A. True
Explanation
Air is important for living things because it contains oxygen, which is essential for the process of respiration. Living organisms, including humans and animals, need oxygen to survive and produce energy. Additionally, air also helps in the transportation of nutrients and removal of waste products from cells. Without air, living things would not be able to breathe and carry out vital metabolic processes, leading to their inability to survive.
