    At room temperature (25°C), water is a liquid because it has the following characteristics of liquid:

    1. At room temperature, water has no shape but has a fixed volume i.e., it occupies the shape of the container in which it is kept.
    2. At room temperature, water flows easily.

    Cells are the basic, fundamental unit of life. So, if we were to break apart an organism to the cellular level, the smallest independent component that we would find would be the cell.

    A cell performs these major functions essential for the growth and development of an organism. Important functions of cell are as follows:

    • All the organisms are made up of cells. They form the structural basis of all the organisms. The cell wall and the cell membrane are the main components that function to provide support and structure to the organism. For eg., the skin is made up of a large number of cells. Xylem present in the vascular plants is made of cells that provide structural support to the plants.
    • In the process of mitosis, the parent cell divides into the daughter cells. Thus, the cells multiply and facilitate the growth in an organism.
    • Cells require energy to carry out various chemical processes. This energy is produced by the cells through a process called photosynthesis in plants and respiration in animals.

    It is difficult to make antiviral medicines than making antibiotics because viruses have few biochemical mechanisms of their own. They enter the host cells and use their machinery for their life processes. So, antiviral medicines will work against the host body. Antibiotics block bacterial synthesis pathways without affecting the body because bacteria use its own metabolic pathway machinery so, it will not affect the host body.

    Evaporation causes cooling. This is based on the fact that when a liquid evaporates, it takes (or draws) the latent heat of vaporization from "another matter" which it touches. This "another mater looses" heat and gets cooled. This is how evaporation causes cooling.
    E.g.- When perfume falls on our hand, our hand feels cool  because perfume is a volatile liquid and gets evaporated rapidly taking away the latent heat of vaporization from our hand.

    Carbon is found elemental form as well as combined form on the Earth.
    In combined state it is present as carbon dioxide in the atmosphere, as carbonate and hydrogen-carbonate salts in various minerals and as life molecules.
    It is through photosynthesis (carried out by life-forms containing chlorophyll) that carbon gets incorporated into life-forms.  Photosynthesis converts carbon dioxide (from the atmosphere or dissolved in water) to glucose in the presence of sunlight by all life-forms that contain chlorophyll. These glucose molecules are either converted into other substances or used to provide energy to the organism for carrying out its life processes or building other molecules.

    Energy is provided through the process of respiration, which converts glucose back into carbon dioxide. In addition, combustion of fuels to provide energy for various needs like heating, cooking, transportation and industrial processes also releases carbon dioxide to atmosphere. Today the percentage of carbon dioxide in the atmosphere has doubled since the industrial revolution. Thus carbon is cycled repeatedly through different forms by the various physical and biological activities.

    Particles are far apart from each other because there are very weak forces of attraction between them. They move fast in all directions. Because of this, gases don't have a definite shape or volume and fill any container. Because there is lots of free space between particles, gases can easily be compressed
