The ground tends to be warmer on a sunny day than on cloudy one . what is the primary type of thermal energy transfer that causes this? a. insulation b. radiation c. conduction d. convection

The answer is Radiation.

Explanation:

The answer would be radiation. Radiation is an emission or transmission of energy in the form of particles that move very quickly. These can cross space or matter. The heat of the sun can be translated into these energy particles that move very quickly. Eventually, this energy manages to make contact with the earth's atmosphere, and is transferred, through radiation, to the ground. That is why on sunny days, the earth pulsed to be warmer than on cloudy days, since the emission of solar radiation is blocked by clouds in the sky.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
