The right answer is Get Energy, Maintain Health, and Reproduce.
Bacteria need the energy to stay alive and reproduce, but the majority are not very demanding in terms of nutrients, they are said to be prototrophic.
A prototroph is a living organism capable of proliferating (living and reproducing) in a basal medium (minimum medium) without requiring the presence of particular growth factors. It synthesizes itself the substances necessary for its proliferation.
The correct answer is (b) Get energy, maintain health and reproduce.
The unicellular organisms must get energy from the food they eat. They maintain their health and keep on reproducing to ensure their existence on earth. For example an unicellular organism like amoeba carry out digestion to obtain the energy from the food it engulf. The vacuoles present in their body helps to maintain homeostasis (health). The vacuoles only carries waste products out of the body. Amoeba reproduce by the process of binary fission. All the above mentioned functions are carried by the amoeba to survive on their own.
Chromosomes contain two identical structures known as sister chromatids. These are formed during cell division and eventually separate into individual chromosomes in the new cells.
Each chromosome contains two identical sister chromatids. During the phase of cell division known as replication, each chromosome duplicates itself to form these two identical chromatids. Joined at a point known as the centromere, these sister chromatids are eventually separated during the later stages of cell division, becoming individual chromosomes in the resulting daughter cells.

The answer is B: Sugar
This is because your body uses Oxygen and Glucose (Sugar) and produces that into ATP, Carbon Dioxide and water vapor
