The formula to calculate population density is a. land area divided by number of populations b. number of populations divided by land area c. number of organisms in a region divided by land area d. land area divided by number of organisms in a region

c. number of organisms in a region divided by land area

Explanation:

A population density is a demographic parameter. It is define as the number of individuals of the population of species living in a particular area of the region in a particular period of time. The population density can be affected by the mortality rate or death rate, immigration rate, emigration rate and birth rate.

The mortality rate or death rate is the number of individuals of the population of species die in an area in particular time.

The birth rate can be define as the number of live births in the population of species in a particular area in a particular time.

The immigration rate can be define as the number of individuals of the species migrated from the native place in a particular time.

The emigration rate can be define as the number of individuals of the same species arrived to the given place in a particular time.

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.
