Answer 2

1. Have scientists provided a universally accepted definition of life?

Scientists have not yet provided a universally accepted definition of life. The concept of life is complex and multifaceted, and different scientific disciplines may have different criteria for defining what constitutes life. However, there are some commonly agreed-upon characteristics that are often used to define living organisms, such as the ability to reproduce, grow and develop, respond to stimuli, and maintain homeostasis.

2. What is a living thing?

A living thing, also known as an organism, is a self-contained entity that exhibits the characteristics of life. Living things are composed of cells, can reproduce, grow and develop, respond to stimuli, and maintain homeostasis. They also acquire energy and nutrients from their environment to carry out their life processes.

3. What is a non-living thing?

A non-living thing, also known as an inanimate object, is something that does not possess the characteristics of life. Non-living things do not grow, reproduce, respond to stimuli, or maintain homeostasis. Examples of non-living things include rocks, water, and machines.

4. What can living things do that non-living things cannot?

Living things have several characteristics that distinguish them from non-living things. Some of the key abilities of living things include:

- Reproduction: Living things can reproduce and produce offspring of their own kind. - Growth and development: Living things can grow in size and complexity over time. - Response to stimuli: Living things can respond to changes in their environment. - Metabolism: Living things can acquire energy from their environment and use it to carry out various life processes. - Homeostasis: Living things can maintain a stable internal environment despite changes in the external environment. - Adaptation: Living things can adapt to their environment over time through genetic changes.

These abilities are not present in non-living things.

5. What do cells contain?

Cells are the basic structural and functional units of living organisms. They contain various components that enable them to carry out their functions. Some of the key components found in cells include:

- Cell membrane: A thin, flexible barrier that surrounds the cell and regulates the movement of substances in and out of the cell. - Cytoplasm: The gel-like substance inside the cell where various cellular processes occur. - Nucleus: The control center of the cell that contains the genetic material (DNA) and regulates cell activities. - Organelles: Specialized structures within the cell that perform specific functions, such as mitochondria for energy production and ribosomes for protein synthesis.

Cells can vary in structure and function depending on the type of organism they belong to.

6. What does genetic information determine?

Genetic information, which is stored in the DNA of living organisms, determines various characteristics and traits of an organism. It contains the instructions for building and maintaining the organism's structure and carrying out its functions. Genetic information determines traits such as physical appearance, behavior, and susceptibility to certain diseases. It also plays a crucial role in the inheritance of traits from one generation to the next.

7. How is growth brought about?

Growth in living organisms is brought about by the increase in the number and size of cells. Cells divide and multiply, leading to an increase in the overall size of the organism. This process is regulated by various growth factors and hormones. Additionally, the acquisition of nutrients and energy from the environment is essential for supporting the growth of living organisms.

8. Can heat be used to drive biological processes?

Yes, heat can be used to drive biological processes. Heat is a form of energy, and living organisms require energy to carry out various life processes. Heat energy is often used in metabolic reactions to facilitate chemical reactions and provide the necessary energy for cellular activities. However, it is important to note that heat alone is not sufficient to sustain life, as living organisms also require other sources of energy, such as food.

9. How do living things acquire energy and nutrients?

Living things acquire energy and nutrients through various means, depending on their specific characteristics and environment. Some common ways in which living things acquire energy and nutrients include:

- Photosynthesis: Plants and some other organisms can convert sunlight into chemical energy through the process of photosynthesis. They use this energy to produce glucose and other organic compounds. - Consumption: Many organisms acquire energy and nutrients by consuming other organisms or organic matter. This can involve eating plants (herbivores), eating other animals (carnivores), or consuming a combination of both (omnivores). - Absorption: Some organisms, such as fungi, can absorb nutrients directly from their environment. They secrete enzymes that break down organic matter, and then absorb the resulting nutrients. - Chemical reactions: Some organisms, such as certain bacteria, can obtain energy and nutrients through chemical reactions with their environment. For example, some bacteria can obtain energy by oxidizing inorganic compounds like hydrogen sulfide or ammonia.

10. What do living things need to stay alive?

Living things need several essential components to stay alive. These include:

- Water: Water is essential for various cellular processes and is involved in maintaining the internal environment of cells. - Nutrients: Living things require a variety of nutrients, including carbohydrates, proteins, fats, vitamins, and minerals, to support their growth, repair, and energy needs. - Oxygen: Many organisms require oxygen for cellular respiration, a process that generates energy from nutrients. - Energy: Living things need a source of energy to carry out their life processes. This energy can come from sunlight (in the case of photosynthetic organisms) or from the consumption of organic matter. - Homeostasis: Living things need to maintain a stable internal environment, which requires mechanisms for regulating temperature, pH, and other physiological parameters.

11. What does the degree of responsiveness depend on?

The degree of responsiveness in living things depends on several factors, including the complexity of the organism's nervous system and sensory organs. More complex organisms, such as humans, have highly developed nervous systems and sensory organs, allowing them to perceive and respond to a wide range of stimuli in their environment. On the other hand, simpler organisms may have more limited responsiveness due to their simpler nervous systems and sensory capabilities.

12. How do movements of living things differ from those of non-living?

Movements of living things differ from those of non-living things in several ways. Living things can exhibit a wide range of movements, including locomotion (movement from one place to another), growth movements (such as plant growth towards light), and internal movements (such as the contraction of muscles). These movements are usually purposeful and controlled by the organism's nervous system.

In contrast, non-living things do not exhibit purposeful movements on their own. Any movement observed in non-living things is usually a result of external forces acting upon them, such as wind or gravity. Non-living things lack the ability to initiate and control movements in response to stimuli.

13. What is homeostasis?

Homeostasis is the ability of living organisms to maintain a stable internal environment despite changes in the external environment. It involves the regulation of various physiological parameters, such as body temperature, pH, and nutrient levels, within a narrow range that is optimal for the organism's survival and function. Homeostasis is achieved through feedback mechanisms that detect changes in the internal environment and initiate appropriate responses to restore balance
