    A reversible chemical reaction is a chemical reaction that can go in both directions; the reactants can change into the products, and the products can change back into the reactants. This happens continually until it reaches a point called equilibrium. Example - nitrogen and hydrogen react together to form ammonia gas.

    No, as the air we exhale is warmer and lighter than the air around us the warm air moves up and escape to the ventilators and the fresh air enters through doors and windows and rashes in to take the warmest is placed so if we get a house with doors and windows but no ventilators a warmer air we breathe out will not be able to escape out the leading to suffocation

    No, as the air we exhale (breathe out) is warmer and lighter than the air around us. The warm air moves up and escapes through the ventilators and the fresh air enters through doors and windows and rushes in to take the warmer air's place. So if we get a house with doors and windows but no ventilators the warmer air we breathe out will not be able to escape out, thus leading to suffocation.

    Plastids are present only in plant cells. There are two types of plastids – chromoplasts (coloured plastids) and leucoplasts (white or colourless plastids). Plastids containing the pigment chlorophyll are known as chloroplasts. Chloroplasts are important for photosynthesis in plants.
    The internal organisation of the plastids consists of numerous membrane layers embedded in a material called the stroma. Plastids are similar to mitochondria in external structure. Like the mitochondria, plastids also have their own DNA and ribosomes.

    Fertilization is the first step in sexual reproduction. When sperms come in contact with an egg, one of the sperms may fuse with the egg. Such fusion of the egg and the sperm is called fertilization. During fertilization, the nuclei of the sperm and the egg fuse to form a single nucleus which results in the formation of a fertilized egg or zygote. It is due to fertilization that the new individual inherits some characteristics from the mother and some from the father.The zygote divides repeatedly to form a ball of hundreds of eggs called an embryo. The embryo moves down the oviduct into the uterus and settles there. It starts developing into a baby by growing body parts such as hands, legs, head, eyes, ears, etc. The stage of the embryo in which all the body parts can be identified is called a foetus. When the development of the foetus is complete, the mother gives birth to the baby.

    A change in which a substance undergoes a change in its physical properties is called a physical change. A physical change is generally reversible. In such a change no new substance is formed.
    Changes in which chemical properties of substance change and a new substance is formed are called chemical changes. Some of the chemical changes are irreversible. Even in case of reversible changes in which chemical properties of substance change and a new substance is formed are called chemical changes. Some of the chemical changes are irreversible. For example: formation of curd from milk, burning of paper, etc.

    Glucose is a simple soluble substance which directly flows into the bloodstream and hence provides instant energy to all the cells. It is formed when carbohydrates are digested so it cannot be broken down into a simpler form thus it works efficiently. If all the glucose is not used immediately it is stored in the liver in form of starch so that it can be used again later. It contains starch and thus is a sugary substance. Energy drinks are also made from glucose to provide instant energy while doing heavy exercises and during medical diseases for eg. in the cases of blood loss the energy in the body is less which results in migrain and other aches caused due to absence of energy.
