Ans: Aerobic Respiration Anaerobic Respiration Takes place in presence of oxygen Takes place in absence of oxygen More energy is released Less energy is released The end products are carbon dioxide, water and energy molecules in the form of ATP…
Ans: Excretion is the process of getting rid of waste materials and harmful substances that the body doesn’t need. Excretion is important because it helps the body maintain a clean and healthy internal environment. Here’s why it matters: a). Removal…
Ans: Transportation of substances in plants and animals involves the movement of essential materials like nutrients, water, gases, and waste products within the organism’s body. The processes and mechanisms for transportation differ between plants and animals: Transportation in Plants: In…
Ans: Enzymes play a crucial role in various life processes by facilitating and regulating biochemical reactions in living organisms. These biological catalysts are essential for maintaining life and ensuring that essential chemical processes occur at the proper rates. Here are…
Ans: Digestion is the process by which the human body breaks down the food we consume into smaller, absorbable molecules that can be used for energy, growth, and repair. It involves both mechanical and chemical processes and occurs in various…
Ans: There are two primary types of nutrition in living organisms: Autotrophic Nutrition: Autotrophic organisms are capable of synthesizing their own organic molecules, primarily carbohydrates, from inorganic substances like carbon dioxide and water. These organisms capture and convert energy from…
Ans: Photosynthesis is a vital process in the plant body that is meant to generate food. It is a process that occurs inside the leaves, and food is produced with the help of the sunlight. The water is broken down…
Ans: Respiration is a chemical process that occurs inside the cells. In living organisms, it is essential in order to generate energy for other vital processes in the body. In human body, it includes burning of nutrients with help of…
Ans: The life processes are all the necessary functions that occur inside an organism’s body for survival. The number and types of these processes vary from organism to organism. In humans, there are five vital processes and one optional process…
Ans: As light travels through a medium, it interacts with the particles present within it. During this interaction, some light rays are absorbed, while others are scattered in different directions. The degree of scattering is influenced by the size of…
Ans: The human eye and vision hold immense significance in our daily lives. They give us the ability to sense our surroundings and provide information that is crucial for communication, safety, and navigation. We can appreciate the beauty of the…
Ans: Corrective lenses, like glasses and contact lenses, enhance vision by altering the way light enters the eye. In cases of nearsightedness (myopia), the lenses are concave, which helps diverge incoming light, allowing it to focus accurately on the retina.…
Ans: The iris regulates the amount of light entering the eye by automatically adjusting the size of the pupil based on the light’s intensity. When there’s ample light, the iris contracts, reducing the pupil’s size to limit the light entering…
Ans: We perceive depth and distance through binocular vision, a process where our brain combines the slightly different images seen by each eye. This disparity in the images arises from the separation of our eyes. The brain calculates the variances…
Ans: When we look at an object, its image lingers on our retina for about 1/16th of a second, even after we stop looking at it. If we view another object during this brief period, the impressions from both objects…
