Cells obtain energy by either capturing light energy through photosynthesis or by breaking down carbohydrates through cellular respiration. In both photosynthesis and cellular respiration, the energy is ultimately derived from the Sun in a A.
reversible process.
B.
highly efficient process which involves no loss of heat to the environment.
C.
one-way process.
D.
pathway that involves taking in heat from the environment at each step.

The correct answer will be option-D

Explanation:

Vastus lateralis or anterolateral thigh is the muscle of the thigh which is the largest and the most powerful muscle in the thigh. The vastus lateralis is recommended as a site for intramuscular injection in infants.

A vaccine or immunoglobulin in infants must be given either in deltoid or the vastus lateralis muscle. When the injection is given in the vastus laterlis, after post-vaccination a temporary pain with tenderness and redness is observed at the site.

Thus, Option-D is the correct answer.
