Answer:
D. Electrical - electromagnetic and thermal
Explanation:
Energy is the capacity to do work, and it exists in various forms. Some of its forms are: nuclear energy, solar energy, electrical energy, mechanical energy, sound energy, light energy, heat/ thermal energy etc. These forms can be transformed from one to another. Example is the conversion of electrical energy into light energy and heat energy by an electrical Tungsten-bulb.
A space heater is an electrical device used for generation of majorly heat energy, thus it is powered by electrical energy. Therefore it transforms electrical energy into electromagnetic and thermal.
Answer:
Water and nutrient uptake.
Explanation:
The root system of a plant functions as conducting tissue for water and mineral nutrients that are essential for metabolic activities of the plant.
<em>Extensive surface area of roots is an adaptation associated with efficient water and mineral nutrient uptake because this will increase the surface area of roots in contact with the soil.</em>
