Question

_____ is the only planet where life is known to exist.
A) The Venus
B) The Mars
C) The Earth
D) The Jupiter

Answer 1

Hint: Humans require oxygen to breathe and can survive in temperatures that are neither too hot nor too cold. Even the power of gravity influences the shape of our body, such as the strength of our bones and muscles. Because other worlds do not have the same conditions as ours, life on them would be considerably different.

Complete answer:
Earth was born 4.5 billion years ago from the same gas and dust nebula that gave birth to the Sun and the other planets. Earth is the third planet from the Sun and the only known life-bearing object in the Universe. It has a natural satellite, the Moon, and orbits the Sun every 365 days.
Let us look at the given options:
A) The Venus: This option is incorrect because there has been no conclusive evidence of past or contemporary life on Venus. The severe surface temperatures on Venus, which reach about 735 K (462 °C; 863 °F) and an atmospheric pressure 90 times that of Earth, make water-based life as we know it on the planet's surface implausible.
B) The Mars: This option is incorrect because it does not have the atmosphere to support life. Carbon dioxide makes up the majority of the atmosphere on Mars. It's also 100 times thinner than Earth's atmosphere, so even if it had a similar composition to our own, humans wouldn't be able to breathe it long enough to survive.
C) The Earth: This is the correct option. The dynamic interplay between genetic opportunity, metabolic competence, environmental challenges, and symbiosis is responsible for the diversity of life on Earth. Microorganisms have controlled Earth's livable environment for most of its life, and it has been susceptible to their metabolism and evolution.
D) The Jupiter: This option is incorrect because Jupiter has no solid surface, attempting to stand on it will cause you to sink and be crushed by the planet's immense pressure. The planet is primarily made up of hydrogen and helium and is a gas giant. There isn't nearly enough water to sustain any known life forms.

Thus, the correct answer is Option C) The Earth.

Note: The dynamic interplay between genetic opportunity, metabolic competence, environmental challenges, and symbiosis is responsible for the diversity of life on Earth. The Earth would be a dead lump of ice-coated rock without the Sun's heat and light. The Sun heats our waters, stirs our atmosphere, creates weather patterns, and provides energy to the growing green plants that support life on Earth with food and oxygen.
