A student uses this apparatus to measure the rate of transpiration in still air and the rate of transpiration in windy conditions. The student calculates the total loss of water after one hour in mg per cm2 of leaf area × 10-4 for the plant in still air. He then repeats this calculation for the plant in windy conditions. (i) The total leaf surface area from which transpiration occurs is 250 cm2 . Calculate the loss of water from this plant in still air in mg per hour.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.

not always but somethings can be reproduced in a laboratory.

answer///(c) the maximum number of organisms an environment can support for a long time; i believe this is correct, plz check luck;
