Introduction The ecosystem is defined as a geographical area composed of living beings and non-living beings interacting with each other. Both of them are interdependent and hence together are responsible for maintaining the balance of the environment. Living beings in an ecosystem are termed biotic factors; they include microbes, plants, and animals. Non-living beings of […]
Introduction The measurement of a system or substance’s heat is called its temperature. The pace of an enzyme-catalyzed reaction typically increases as the temperature rises in most chemical processes. Temperature is the internal energy contained within a particular system. Temperature can be measured by a thermometer. Temperature is measured in degrees Celsius, which is written […]
Introduction Every living thing engages in metabolic processes that produce compounds that, if allowed to build up in the body, could be poisonous. These materials are regarded as excretory wastes. Depending on several internal or external conditions, each organism uses a different technique to remove these wastes. We shall learn more about these excretory processes […]
Introduction The human body is a complex structure made up of several organs that are arranged into different systems and are designed to perform specific functions during various life events. To stay healthy, each of these systems needs a constant supply of oxygen and nutrients. The metabolic wastes produced by each of these systems must […]
Introduction The widely recognized nebular theory postulated that a massive cloud of dust including hydrogen and other gases created the solar system, including the planet earth. Small earthly particles like iron and nickel were created as a result of the earth’s contraction, rotation, and lowering of temperatures. The planet was created approximately 4.5 billion years […]
Introduction The topmost layer of the earth is called soil, and it is made up of several elements. Environmental elements like water, wind, temperature, and even living things usually have an impact on them. One type of soil may not have the same physical or chemical properties as another. The soil is now inhabited by […]
Introduction Agriculture is the practice of raising animals and cultivating crops. To meet the growing need of the population, the seed is crucial in the development of palatable foods. It is a fertilized ovule that germinates to give rise to new plants. The crucial phase in agriculture is choosing good quality seeds because they can […]
Introduction A system of ductless glands that secrete hormones is known as an endocrine gland system. In the blood, hormones are carried directly to their target organs as chemical messengers. As hormones are synthesized in certain tissues, they trigger a cascade of events that allow for certain cellular responses. Adrenal glands are located above the […]
Introduction Humans are sexually dimorphic i.e., they have two distinct sexes- male and female. This dimorphism is seen in humans in favour of sexual reproduction which is the main reason for the diversity among humans. Humans progress through a transitional stage known as adolescence as they develop from childhood to adulthood and reach reproductive maturity. […]
