The International Tropical Timber Organization (ITTO) is an intergovernmental organization that promotes conservation of tropical forest resources and their sustainable management, use and trade.Headquarters: Yokohama, Japan

Temperate Cyclones are cyclones of mid-latitudes and hence are primarily under influence of permanent winds of mid-latitudes i.e. westerlies. Their movement is therefore eastwards of their origin with average velocity of 32km per hour in summers and 48km per hour in winters.

Movement of Tropical CyclonesNormally, they move from east to west under the influence of trade winds because trade winds are permanent winds of tropical latitudes. The general direction is therefore westwards from their origin. They advance with varying velocities. Weak cyclones move at the speed of about 32km per hour while hurricanes attain the velocity of 180km per hour or more.

The Chambal's lower course is lined by belt of badland gullies resulting from accelerated soil erosion and is the site of a major projectin soil conservation.Chambal Project is a joint project from both Madhya Pradesh and Rajasthan government, which aims at harvesting the Chambal River for irrigation, power prevention and control of soil erosion in the valley

Urea is produced in the liver and is a metabolite (breakdown product) of amino acids. Ammonium ions are formed in the breakdown of amino acids. Some are used in the biosynthesis of nitrogen compounds. Excess ammonium ions are converted to urea.

During respiration, about 97% of oxygen is transported by Red Blood Cells in blood and the remaining 3% gets dissolved in the plasma.Around 20-25% of carbon dioxide is carried by haemoglobin as carbamino-haemoglobin.

Oxygen enters the blood from the lungs and carbon dioxide is expelled out of the blood into the lungs. The blood serves to transport both gases. Oxygen is carried to the cells. Carbon dioxide is carried away from the cells.

Histones are highly alkaline proteins found in eukaryotic cell nucleusthat package and order the DNA into structural units called nucleosomes. They are the chief protein components of chromatin, acting as spools around which DNA winds, and playrole in gene regulation.

Hooke's law states that within the elastic limit, stress developed is directly proportional to the strain produced in a body.Hooke’s law is valid only in the linear part of stress-strain curve. Hence, statement 1 is correct.
