A class of students performed the heat transfer experiment shown in the picture. In the experiment, three plastic dishes were partially filled with equal amounts of dark soil, light soil, and water. Thermometers were placed in each dish, and the dishes were placed under a heating lamp. The substances were left under the heating lamp for ten minutes, and their temperatures were observed and recorded
Dark soil
Water
Light soil
Which correctly predicts the outcome of this experiment?
СА
The dark soil will heat up the fastest as heat transfers from the lamp to the surface of the soil via radiation, and then the soil will absorb the heat through convection
Ов
The water will heat up the fastest as heat transfers from the lamp to the surface of the water via radiation, and then the water will absorb the heat through convection
The dark soil will heat up fastest as the heat transfers from the lamp to the surface of the soil via radiation, and then the soil will absorb the heat through conduction
The water will heat up fastest as the heat transfers from the lamp to the surface of the water via conduction, and then the water will absorb the heat through convection

i believe the answer would be b. hope it : )

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.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

it is called the mitotic spindle
