1^o C to 13^o C temperature and 50 to 250 cm rainfall account for the formation of a major biome

Distinct seasons and annual variation in precipitation leads to formation of major biomes. Reason:- Distinct seasons and annual variation in precipitation leads to development of different climatic conditions which favours growth and development differentially.

Mark the correct statements about major abiotic factors . I . Temperature on land veries seasonally, increase progressively from the equator towards the from plains to the mountain tops . II. Light is important in animals as they use the diurnal seasonal variations in light intensity and duration as cues for timing their forging, reproductive and migratory activities. III. Various characteristics of the soil such as soil composition, grain size and aggregation determine the percolation and water holding capacity of the soils . IV. The salt concentration is more than 5% in inland waters

The graph given below is showing biome distribution with respect to annual temperature and precipitation. Identify A, B and C, respectively.

Heat is flowing through a rod of length 25.0 cm having cross-sectional area 8.80 cm^(2) . The coefficient of thermal conductivity for the material of the rod is K = 9.2 xx 10^(-2) kcal s^(-1) m^(-1) .^(@)C^(-1) . The Temperatures of the ends of the rod are 125^(@)C and 0^(@)C in the steady state. Calculate (i) temeprature gradient in the rod (ii) temperature of a point at a distance of 10.0 cm from the hot end and (iii) rate of flow of heat.

A sphere with diameter of 80cm is held at a temperature of 250^(@)C and is radiating en-ergy If the intensity of the radiation detected at a distance of 2.0m from the sphere 's cnetre is 102 W//m^(2) What is the emissivity of the shere ? .

A calorimeter of water equivalent 10 g contains a liquid of mass 50 g at 40 .^(@)C . When m gram of ice at -10^(@)C is put into the calorimeter and the mixture is allowed to attain equilibrium, the final temperature was found to be 20^(@)C . It is known that specific heat capacity of the liquid changes with temperature as S = (1+(theta)/(500)) cal g^(-1) .^(@)C^(-1) where theta is temperature in .^(@)C . The specific heat capacity of ice, water and the calorimeter remains constant and values are S_("ice") = 0.5 cal g^(-1) .^(@)C^(-1), S_("water") = 1.0 cal g^(-1) .^(@)C^(-1) and latent heat of fusion of ice is L_(f) = 80 cal g^(-1) . Assume no heat loss to the surrounding and calculate the value of m.
