Environmental Pollution  What is the Environment? The grand total and inclusion of all living and nonliving elements and their effects on human life is referred to as the environment. Water, land, sunlight, rocks, and air are examples of non-living or abiotic elements, while all living or biotic elements are animals, plants, forests, fisheries, and birds.  Healthy living and the existence of life on Earth are greatly influenced by the environment. We all heavily rely on the environment for food, water, and other necessities of life because the Earth is home to many different species of living things including human beings.   As a result, conserving and safeguarding our environment is critical for all of us including animals and other living organisms. What is the Pollution? The introduction of hazardous substances into the environment is pollution. The term "pollutant" refers to these harmful substances. Natural pollutants include ash from volcanoes. They can also be...

Why Does a Matter Change Its State? Matter needs to change its state so that new things can be formed. For example, we need a change in the states of matter (liquid) to form clouds and start raining. Similarly, certain changes in the states of matter are so important for all living things including human beings.  All forms of matter (solids, liquids, gases, and plasma) change their state from one form to another naturally as well artificially. Similarly, the reasons behind these certain changes for all forms of matter are temperature, pressure, heat, and force. These changes happen in the form of melting, freezing, boiling, evaporation, sublimation, and condensation.  From the Chemistry point of view, there are two main changes that are mentioned and explained below. Chemical Change Physical Change What is a Chemical Change in Matter? A chemical change involves the transformation of one material into another, the formation of new materials with distinct properties, and the fo...

What is the Reproduction in Plants? Reproduction in plants is the course of the development of new posterity in plants which can be achieved by sexual or abiogenetic proliferation. The fusion of gametes during sexual reproduction results in the birth of offspring that are genetically distinct from either parent.  Without the fusion of gametes, asexual reproduction results in new individuals—clonal plants—that are genetically identical to the parent plant and each other unless mutations occur. Similarly,  The seed, germination, growth, reproduction, pollination, and seed spreading stages are the most important processes that take place through a flower and hence plants reproduce their offspring. The reproduction process in plants is very important for humans and animals because plants not only keep our environment clean and healthy but also give us food so we can eat and stay alive. Which are the Main Types of Reproduction in Plants? There are two ways that plants reproduc...

  What is an Atom? An atom is the fundamental, neutral particle of matter. An atom has electrons in its valence shells outside of the nucleus, which is made up of protons and neutrons in the center. Atoms are extremely small, typically having a width of around 100 picometers. The nucleus contains more than 99.94% of an atom's mass.  The protons have a positive electric charge, the electrons have a negative electric charge, and the neutrons have no electric charge. The atom is electrically neutral if the number of protons and electrons is the same. Ions (cations and anions)are atoms that have a total charge that is either negative or positive if they have more or fewer electrons than protons.  What is the Structure of an Atom? An atom has a central nucleus that is surrounded in its valencies (shells) by one or more electrons that are negatively charged. Protons and neutrons, two relatively heavy particles, are found in the positively charged nucleus. Therefore, an atom's...

What is the Human System? From the scientific point of view, the human body is a complex working machine that works round the clock. Similarly, the human body has different systems that work together and perform different important biological functions including breathing, circulation of blood, digestion of food, excretion, and reproduction, etc.  Additionally, in any particular human system, different organs perform certain activities together and hence make a specific system such as breathing and digestion, etc.  Which are the 12 Systems in the Human Body? The systematic operation of the human body astonishes us to the core when we observe it deeply and scientifically. Similarly, the human body begins as a pair of cells (a zygote) and progresses through the formation of tissues, organs, systems, and ultimately an organism. Let's now read and know about 12 different systems in the human body that make our life possible.  Cardiovascular System Digestive System Endocrine S...
