A person exhales carbon dioxide and moisture. Which example of the characteristics of life is most similar? A. A gazelle runs away from a lioness. B. An algal cell has a defined boundary. C. A dog defecates when outdoors on a walk. D. A 12-year-old boy’s voice breaks.
Answers
The act of exhaling carbon dioxide and releasing moisture symbolises physical activity. In other words, when a person is in motion or at work, his/her body functions two of the most vital functions - respiration (exhalation of carbon dioxide) and perspiration (release of moisture, i.e. sweat). Let us compare this occurrence with the given options.
Option (A) matches with the given context. This is because a gazelle, running away from a lioness, will experience faster rates of respiration (at one point, even anaerobic respiration), along with perspiration to cool down the body temperature.
Option (B) is irrelevant from this aspect. An algae having a definite boundary has no relation with release of energy in any way.
Option (C) is an example of excretion, which is not remotely connected with the given context.
Option (D) is an sign of puberty in the body of an adolescent male.
Therefore, the answer to your question will be Option (A) A gazelle runs away from a lioness.
