Final answer:
The seven functions of life carried out by all unicellular organisms are nutrition, transport, respiration, excretion, regulation, growth, and reproduction.
Step-by-step explanation:
All unicellular organisms carry out the seven functions of life which are essential to their survival and continuity. The correct answer to the given question is:
C) Nutrition, transport, respiration, excretion, regulation, growth, reproduction
These functions are integral parts of an organism's existence, ensuring it can maintain and propagate life. Nutrition involves the intake and processing of nutrients, while transport refers to the distribution of materials throughout the cell. Respiration is the process by which cells convert glucose and oxygen into energy. Excretion is the removal of waste products, and regulation encompasses the various ways in which organisms control internal processes. Growth is the increase in size or number of cells, and reproduction is the process by which organisms produce offspring.
