Proposition is a statement about observable phenomena(concepts) that may be judged to be true or false.When a proposition is so formulated for empirical testing ,we call it a hypothesis..As a declarative statement about the relationship between two or more variables, a hypothesis is of tentative and conjectural nature.
Visual symptoms of scabies: what do they look like, and where are they found? Scabies can be on almost any part of the body, but often the hands are the first area affected. Scabies also particularly like to live in skin folds and crevices, such as those on the inside of the wrist.
Scabies is caused by a mite (like a tiny insect) called Sarcoptes scabiei. The mite is a parasite, meaning it lives off the host (a human) with no benefit to the host. Scabies mites are so tiny, you can't see them with the naked eye. They have a cream-coloured body, bristles and spines on their back, and four pairs of legs.
