    Sericulture, or silk farming, is the cultivation of silkworms to produce silk. Although there are several commercial species of silkworms, Bombyx mori is the most widely used and intensively studied silkworm. Silk was believed to have first been produced in China as early as the Neolithic Period.

    The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. ... Prokaryotes, on the other hand, have no membrane-bound organelles

    1Thank You

    Pra Jit 4 years, 1 month ago

    Prokaryotic cells- they are not membrane bound, they don't have a well defined nucleus, EUKARIOTIC CELLS are membrane bound, they have a well defined nucleus.

    Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement. For example, 50 km/hr (31 mph) describes the speed at which a car is traveling along a road, while 50 km/hr west describes the velocity at which it is traveling.

    Shrishti Rathore 4 years ago

    Speed - The distance covered by a body per unit time is called speed . Speed is a scalar quantity. It is always positive. The S.I. unit of speed is metre(m). Velocity - The displacement travelled by a body per unit time is called velocity. Velocity is a vector quantity. It may be positive, negative or zero. The S.I. unit of velocity is metre (m).
