    A syndrome is a set of medical signs and symptoms which are correlated with each other and often associated with a particular disease or disorder. 
    When the functioning or the appearance of one or more systems of the body will change for the worse, it gives certain abnormal signs of the disease. These visual changes in human beings are called symptoms. Symptoms give indication of the presence of a particular disease.

    Living things exist and are alive and are made of microscopic structures called cells. They grow and exhibit movement or locomotion. They experience metabolism, which includes anabolic and catabolic reactions.

    Living things are capable of producing a new life which is of their own kind through the process of reproduction. Living things have a particular life span and are not immortal.

    Diffusion is an important process through which exchange of gases takes place in a cell. This process is mainly directed by the difference in pressure of concentration. Hence the gases move from a highly concentrated region to a region of low concentration. Diffusion in plant cells mainly takes place during the process of photosynthesis where carbon dioxide diffuses into plant cells via the stomata on the leaf.

    Initially the car moves under acceleration for 5 sec. So, the velocity-time graph has a slope in first 5 sec and then it moves at a constant speed. So, the curve will be a straight line parallel to time axis where the value of speed does not change.

    By the late 1970s, scientists were able to prove that chemical substances that were used in air conditioners, refrigerators and aerosol cans were causing damage to the ozone layer. In 1985, a huge hole was discovered in the ozone layer over Antarctica. This hole allowed hazardous levels of ultraviolet (UV) radiation to reach the earth’s surface. 

    The Vienna Convention for the Protection of the Ozone Layer was signed in 1985 under which UN member countries recognized the importance of curbing damage to the ozone layer. As per the Convention’s provisions, countries agreed to adopt the Montreal Protocol to further the goals of the Vienna Convention.

    Planning is ascertaining prior to what to do and how to do. It is one of the primary managerial duties. Before doing something, the manager must form an opinion on how to work on a specific job. Hence, planning is firmly correlated with discovery and creativity. But the manager would first have to set goals. Planning is an essential step what managers at all levels take. It needs holding on to the decisions since it includes selecting a choice from alternative ways of performance.

    The SI unit of work is joule (J). Joule is defined as the work done by a force of one newton causing a displacement of one meter. Sometimes, newton-metre (N-m) is also used for measuring work. However, as this unit is also used for torque it can get quite confusing.
