Fish is indeed an example of a living thing. Living things are characterized by having the ability to grow, reproduce, respond to stimuli, and maintain homeostasis. Fish exhibit all of these characteristics, as they grow from eggs to adults, reproduce by laying eggs or giving birth to live young, respond to changes in their environment, and regulate their internal conditions to survive. Therefore, fish can be classified as living organisms.

This statement is incorrect. We do not use our ears to eat. Eating involves the use of our mouth and digestive system, not our ears. Our ears are used for hearing, not for the process of consuming food.

The living planet refers to Earth because it is the only known planet that supports and sustains life. Earth has a diverse range of ecosystems, including land, water, and atmosphere, which provide the necessary conditions for various forms of life to exist. It has a balanced climate, abundant resources, and a complex web of interconnected organisms that depend on each other for survival. Earth's unique combination of factors makes it the ideal habitat for a wide range of species, including humans.

The statement "Earth is the smallest planet in the solar system" is incorrect. Earth is actually the fifth largest planet in the solar system. The smallest planet in the solar system is Mercury, followed by Mars and Venus.

This statement is incorrect. Human beings are indeed living things. Living things are characterized by their ability to grow, reproduce, respond to stimuli, and maintain homeostasis. Human beings possess all of these characteristics, making them living organisms. Therefore, the correct answer is False.

Snakes are indeed reptiles. Reptiles are a group of cold-blooded vertebrates that have scaly skin and lay eggs on land. Snakes belong to the reptile class and possess all the characteristic features of reptiles, such as being cold-blooded, having scales, and laying eggs. Therefore, the statement "Snake is a reptile" is true.

Jupiter is the correct answer because it is the largest planet in our solar system. It is more than 11 times the diameter of Earth and has a mass that is more than 2.5 times the mass of all the other planets combined. Jupiter's size and mass make it the biggest planet in our solar system.

Chlorophyll is the correct answer because it is a green pigment found in plants. It is responsible for capturing sunlight during photosynthesis, which is essential for plants to produce food. Chlorophyll absorbs blue and red light, reflecting green light, which gives plants their characteristic green color. Carotene is another pigment found in plants, but it is responsible for the orange color in carrots, not green. Water and air are not pigments and do not contribute to the green color in plants.

Mercury is the correct answer because it is the closest planet to the sun in our solar system. It is located only about 36 million miles away from the sun, making it the first planet in the order of distance from the sun. Venus, Neptune, and Pluto are all farther away from the sun compared to Mercury.

Wings are not part of plants. Roots, trunk, and leaves are all essential parts of a plant's structure and function. Roots anchor the plant and absorb water and nutrients from the soil. The trunk provides support and transports water and nutrients between the roots and leaves. Leaves are responsible for photosynthesis, where they capture sunlight and convert it into energy for the plant. Wings, on the other hand, are a characteristic feature of animals, specifically birds, insects, and bats, which allow them to fly.

This statement is incorrect. The nose is indeed a part of the body. It is an organ located on the face that is responsible for the sense of smell and also plays a role in breathing.

The statement "There are only 10 planets in the solar system" is incorrect. As of now, there are officially eight planets in the solar system, namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto, which was once considered the ninth planet, was reclassified as a "dwarf planet" by the International Astronomical Union in 2006. Therefore, the correct answer is False.

Photosynthesis is a process in which plants use sunlight to convert carbon dioxide and water into glucose and oxygen. This process requires light energy, so it cannot occur at night when there is no sunlight. Therefore, the statement that photosynthesis takes place at night is false.

A bottle is an example of a solid because it has a definite shape and volume. It does not flow or take the shape of its container like a liquid (water) or a gas (oxygen). Ink, on the other hand, is a liquid and does not have a definite shape or volume.

Living things do die, which means that the statement "they do not die" is not true. Death is a natural part of the life cycle for all living organisms. It is the cessation of vital functions and the end of life. All living things, including plants, animals, and humans, eventually die due to various factors such as aging, disease, or injury. Death allows for the recycling of nutrients and energy in ecosystems, ensuring the continuation of life.

The correct answer is "bag" because a bag is a physical object that has mass and occupies space, which are characteristics of matter. Love, dream, and ambition are abstract concepts or emotions that do not possess these physical properties.

Matter refers to anything that occupies space and has mass. It includes solids, liquids, and gases. Matter can exist in various forms and can be observed and measured. It is the fundamental substance that makes up the physical universe and everything around us.

The statement is incorrect. Animals that have scales are not mammals. Mammals are a distinct group of animals that have hair or fur, give birth to live young, and nurse their young with milk. Scales are typically found on reptiles, such as snakes and lizards. Mammals, on the other hand, have different skin coverings like hair or fur. Therefore, the correct answer is false.

Saturn is considered the most beautiful planet in the solar system because of its ring. The planet is known for its stunning and prominent ring system, which consists of ice particles, dust, and rocks. This ring system is unique to Saturn and adds to its overall aesthetic appeal. The rings are visible from Earth and have captivated scientists and observers for centuries, making Saturn a visually striking planet.

Photosynthesis is the process by which plants convert sunlight into energy, and it occurs in the chloroplasts of plant cells, primarily in the leaves. The roots of plants are responsible for absorbing water and nutrients from the soil, but they do not participate in photosynthesis. Therefore, the statement that photosynthesis can be found in the roots of plants is false.

The question asks for parts of the eye that are not included in the given options. The retina, cornea, and eyelid are all parts of the eye, but cilia are not. Cilia are hair-like structures found in various parts of the body, such as the respiratory tract, that help with movement. While cilia are not part of the eye, they are still present in other areas of the body.

Animals that feed on meat are called carnivores. This term is derived from the Latin words "carnis" meaning flesh and "vorare" meaning to devour. Carnivores have adaptations such as sharp teeth and claws to catch and kill their prey. They primarily consume the flesh of other animals as their main source of nutrition. Examples of carnivores include lions, tigers, and wolves.

Roots are the part of the plants that are responsible for absorbing water in the soil. They have specialized structures called root hairs that increase the surface area for water absorption. The roots also play a crucial role in anchoring the plant in the ground and storing nutrients. Through their network of roots, plants can efficiently uptake water and essential minerals from the soil, ensuring their survival and growth.

Animals that feed on both grasses and meat are called omnivores. Omnivores have a diverse diet that includes both plant and animal matter. They have the ability to digest and derive nutrients from both types of food sources. This dietary flexibility allows omnivores to adapt to a wide range of environments and food availability. Some examples of omnivores include humans, bears, raccoons, and pigs.

Photosynthesis is the process by which plants convert sunlight into energy. Sunlight provides the necessary light energy for photosynthesis to occur. It is absorbed by chlorophyll, a pigment in plant cells, and is used to power the chemical reactions that convert carbon dioxide and water into glucose and oxygen. Therefore, sunlight is an essential component of photosynthesis as it is the source of energy that drives the entire process.

Animals that eat grasses are called herbivores. Herbivores are a type of animal that primarily feeds on plants, including grasses, leaves, and other vegetation. They have specialized digestive systems that allow them to break down and extract nutrients from plant material. Examples of herbivores include cows, deer, rabbits, and many species of insects.

Glucose is the end product of photosynthesis. During photosynthesis, plants convert sunlight, water, and carbon dioxide into glucose and oxygen. Glucose is a simple sugar that serves as a source of energy for plants and other organisms. It is also used to produce other essential molecules, such as cellulose and starch, which are important for plant growth and development. Therefore, glucose is the correct answer as it is the primary product of photosynthesis.

The energy that we receive from the sun is known as solar energy. Solar energy is derived from the sun's radiation and is converted into usable forms of energy such as heat and electricity. This renewable source of energy is harnessed through various technologies like solar panels and solar thermal systems. Solar energy is considered clean and sustainable, making it an important alternative to fossil fuels in order to reduce greenhouse gas emissions and combat climate change.

Cilia are responsible for filtering small particles inside our nose. Cilia are tiny hair-like structures that line the nasal passages. They move in coordinated waves, helping to trap and remove dust, pollen, and other small particles from the air we breathe. This filtration process is important for keeping our respiratory system clean and preventing these particles from entering our lungs.

Chlorophyll is the green pigment found in plants that is responsible for absorbing light energy during photosynthesis. It is essential for the process of converting sunlight into chemical energy, which is then used by plants to produce glucose and oxygen. Chlorophyll molecules are located in the chloroplasts of plant cells and are what give plants their green color.
