What unit is used to measure surface temperature of the planets? a. kelvin c. degrees celsius b. degrees fahrenheit d. angstroms

The correct answer is option A. Kelvin.

Explanation:

Kelvin is the is unit of temperature measuring like Celsius and Fahrenheit. The planet's temperature is mostly measured in the kelvin unit of temperature however degree Celsius and degree Fahrenheit also use to measuring in many cases.  

Kelvin is an international unit of temperature which is equal to the -273 degree celsius and in planetary science mostly kelvin is used as the unit of measurement.

Thus, the correct answer is option - a. kelvin

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.
