CO2 = Carbon + two Oxygen
Glucose= C6H12O6 = six Carbon + twelve Hydrogen + six Oxygen
so the answer is Carbon and Oxygen.
I believe the answer is B. Homoiothermal
Solar energy is energy that comes from the sun and is captured by solar cells. These cells transform the energy of photons of light into electrical energy. One mechanism is the energization of electrons, here the energy of the photons is transferred to the electrons, which can already be considered electric energy.
As for the hydroelectric energy, here the waterfalls or rivers flow driving a turbine, which will transform the movement into usable electric energy as it rotates.
Evolution is a scientific theory as its ideas are supported by facts and inference
there is no clear evidence about plants evolving in the desert, or fossils of any kind of cactus despite their distribution over a large area. But, scientists are of the opinion that they acquired specific attributes millions of years ago, as a response to the vastly changing climate and conditions.
-Desert plant root system
A typical desert plant has a deep root system, which is a specific physical mechanism. As the roots grow deep down the soil, they absorb soil water, which is then transported to the upper portions of the plant.
-Desert plant leaves
Bear small foliage with waxy surface to minimize transpiration (loss of water through stomatal pores), which in turn, helps to conserve water.
