The characteristics of life: many are listed in the passage describing viruses. one important piece of evidence arguing against life for viruses is implied by the passage; not stated directly. viruses are not living, because, as implied by the passage, they a) have no dna. b) lack a nucleus. c) are not cellular. d) do not reproduce.

The correct answer will be option-C

Explanation:

A biologist has always tried to distinguish the living things from non-living things and suggested eight unique features of the living world. The first characteristics feature is that living organism must be cellular, must contain genetic material and should reproduce and perform metabolic reactions.

Since a virus is a particle composed of genetic material and proteins enclosing it, therefore it is not considered a cellular entity and does not fulfill the criterion of a living world.

Thus, Option-C is the correct answer.

C. Are Not Cellular

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
