The formation of foam is evidence that

A) photosynthesis

B) protein synthesis

C) respiration

D) cell division

Is taking place because

A) oxygen

B) yeast

C) carbon dioxide

D) glucose

Is a product of

A) protein synthesis

B) respiration

C) cell division

D) photosynthesis

C) respiration

C) carbon dioxide

B) respiration

Explanation:

In the process of respiration at cellular level, glucose is com busted in the presence of oxygen to produce carbon dioxide and water.  

The chemical equation is as follows -  

C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy  

The carbon dioxide released at the end of respiration is responsible for producing the foam especially during the cell respiration in anaerobic condition.  

Hence, correct options are

C) respiration

C) carbon dioxide

B) respiration

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
