Cellular Respiration occurs in 4 major stages: Glycolysis, NADH
degeneration, Citric acid (or Kreb's) cycle and Electron Transport
Chain. Glycolysis occurs in the cytosol or cytoplasm of the cell. If
oxygen is present, then the next three stages would occur, otherwise
lactic acid or alcohol fermentation would occur. NADH degenration and
Citric acid cycle occur in the matrix of the mitochondria while Electron
Transport Chain occurs in the intermembranal space of the mitochondria.
Most of cell respiration occurs in the mitochondria though. Hope this
helped!
I must say this is a very complete answer but if i might
add,of every part of a cell involved in cellular respiration,the only
organelle is the mitochondria meaning that is the answer.

Hello! Your answer would be C, They regulate body temperature through behavioral mechanisms.
An endothermic animal is one which is capable of maintaining its own body temperature. They do this through physiological mechanisms, which is what the last choice is saying - these involve things such as hormones, sweating, etc.
These endothermic animals are considered warm blooded. This is because they can make their own body heat. Humans and other mammals are endothermic. We generate our own heat - we don't rely on sunbathing or shade to cool down or heat up our <u>internal</u> body temperature.
Hope this helps!
