Advantages

1. There are no problems related to tariffs and exchange rates.

2. Shipping costs may not be there at all, or may be very low.

3. It helps to create more jobs within the country.

4. It facilitates the exchange of goods within the country.

5. It helps in the growth of the economy.

6. It helps to improve the standard of living of the people.

7. It ensures the availability of raw materials and helps in the growth of an industry.

8. It also helps in foreign trade because the traders from other countries contact the internal traders to get the products.

Disadvantages

1. A large amount of capital is required to start and run the trade.

2. It may not be possible to obtain professional management due to lack of funds.

Neanderthal, (Homo neanderthalensis, Homo sapiens neanderthalensis), also spelled Neandertal, member of a group of archaic humans who emerged at least 200,000 years ago during the Pleistocene Epoch (about 2.6 million to 11,700 years ago) and were replaced or assimilated by early modern human populations (Homo sapiens) between 35,000 and perhaps 24,000 years ago. Neanderthals inhabited Eurasia from the Atlantic regions of Europe eastward to Central Asia, from as far north as present-day Belgium and as far south as the Mediterranean and southwest Asia.

Capillaries are very tiny blood vessels — so small that a single red blood cell can barely fit through them. They help to connect your arteries and veins in addition to facilitating the exchange of certain elements between your blood and tissues. Capillaries are the smallest of the body's blood vessels. They are only one cell thick, and they are the sites of the transfer of oxygen and other nutrients from the bloodstream to other tissues in the body. During early embryonic development new capillaries are formed through vasculogenesis, the process of blood vessel formation that occurs through a de novo production of endothelial cells which then form vascular tubes.

It states that the gravitational field outside a spherical shell having total mass M is the same as if the entire mass M is concentrated at its centre (centre of mass). And the gravitational field inside a spherical shell is zero.

The state of being turgid or swollen, especially due to high fluid content is called turgidity.

Turgidity is very important to plants as it helps in the maintenance of rigidity and stability of plant tissue

• The response of plants to periods of day/night is termed photoperiodism.
• Some plants require the exposure to light for a period exceding a well-defined critical duration known as long day plants, whereas others must be exposed to light for a period less than this critical duration before the flowering is initiated in them, known as short day plants.
• The plants in which there is no correlation between exposure to light duration and induction of flowering response; such plants are called day-neutral plants.
• The site of perception of light/dark duration are the leaves.
• There is a hormonal substance, which migrates from leaves to shoot apices for inducing flowering only when the plants are exposed to the necessary inductive photoperiod.
