Physical or mental conditions that endanger the woman’s health if the pregnancy is continue Types...

Radioactivity is the disposition of certain elements to send out rays on their own. This makes the nuclei break down. It also refers to the particles which are emitted from nuclei as a result of nuclear instability. Because the nucleus experiences the intense conflict between the two stronger forces in nature, it should not be surprising that there are many nuclear isotopes which are unstable and emit some kind of radiation. The most common types of radiation are called alpha, beta and gamma radiation, but there are several other varieties of radioactive decay. The atom has a nucleus around which electrons evolve. The nucleus contains protons and neutrons. A proton has a positive electric charge while the neutron is neutral...

This is an unintended pregnancy during adolescence and it occurs in females under the age 20. Teen pregnancies carry extra health risks to both the mother and the baby. Pregnant teenagers face many of the same pregnancy related issues as other women.  There are, however, additional concerns for those under 15 of age as they are less likely to be physically developed enough to sustain a healthy pregnancy or to give birth. It is common that at this age, the girl has not completed her education and is completely dependent upon her parents thus unable to provide for the unborn child....

Over the years science has developed many processes and products which have conferred on the subject the formidable stature it has at the present time. Science could be used productively, such as in the production of food, curing of diseases, earning income for nations and individuals, gainful employment, etc. Science could be used destructively, such as in atomic bomb production, poisons, nuclear war, production of weapons of war and mass destruction, abortions, etc. The view of science, even in the circumstances given above as either productive or destructive, depends on which side one is considering. It should be emphasized here that when a scientist invents or discovers a thing, he/she does not do it with the intention of causing harm...

Soil is the upper layer of the earth on which  we build houses, plant food crops, etc. All soils are mixtures of different sizes of particles. soil contains mineral salts for plant growth and some animals live in the soil. Types of Soil There are three types of soil. These are: Sandy soil, Loamy soil and Clayey soil. Each soil type has its characteristic properties. Composition of Types of Soil Sandy soils contain a high proportion of large particles (sand) Clayey soil contains a high proportion of small particles (clay and silt). Loamy soils contain nearly equal amounts of sand, clay and silt. It is the most fertile soil for agricultural purposes. Characteristics Properties of Sandy Soil, Loamy Soil and...
