Radioactive Waste - Waste products from nuclear power stations etc. are becoming a serious problem. They should be put where the radiation can do no harm. Unfortunately, there is no way of stopping a radioactive nucleus from emitting radiation. Nuclear energy has some advantages..

Transportation whether in plants or animals is the key to the efficient assimilation of the nutrients that the organisms synthesise, get from their environment or digest. The study of these processes helps us in many ways. The study of transport mechanisms in plants helps us to understand..

Importance of Studying Transportation - Transportation whether in plants or animals is the key to the efficient assimilation of the nutrients that the organisms synthesise, get from their environment or digest. The study of these processes helps us in many ways. The study of transport mec..

Environment is defined as the surroundings in which the organism lives. It has two components - abiotic and biotic. The abiotic environment includes the air (atmosphere), water (hydrosphere) and land (lithosphere). The biotic environment includes the plants, animals and the microbes. ..

The age of fossils of plant or animal origin can be determined by carbon dating technique developed by Willard Libby in 1949. The radioactive isotope of carbon ( 6 C 1 4 ) is used to determine the date at which an animal or plant had died. Carbon Dating The metho..

Water constitutes nearly three-fourths of the Earth's surface and it composes a large proportion of all living plant and animal matter. Approximately 70% of human body is water. Man drinks about 2 liters of water daily and it is required in abundance for domestic use, agricultural activit..

. When the plant or animal dies fresh carbon is no longer taken in and the C - 14, which is present, decays. Thus, the length of time a specimen has been dead may be determined by the activity of the C - 14, which remains in it. Carbon - dating has therefore become an important tool for a..

>It can lead to illness or even death in case of humans and animals. The growth of some plants can be retarded and this may cause them severe injury. It results in corrosion of metals, building materials and marble. Some pollutants distribute themselves over long distances in short period..

. Its sources are sewage that includes organic matter, industries, agricultural chemicals, oil spill, etc. The major pollutants are the organic matter of the sewer, metallic substances and other inorgaic chemicals from the industries, hot water, oil, inorganic fertilizers and pesticides. Some of th..

Energy - Energy can be defined as the ability to do work. A good source of energy would be the one which would: do a large amount of work per unit volume or mass be easily accessible be easy to store and transport and be economical Fossil Fuel Fossil fuel is a hydrocarbon deposit, such as petroleum..
