1. The problem asks for two reasons why plants, animals, and humans cannot live on Jupiter. 2. First, Jupiter is a gas giant with no solid surface, so there is no stable ground for living organisms to stand or grow on. 3. Second, Jupiter's atmosphere is mostly hydrogen and helium with extreme pressure and temperature conditions that are inhospitable for life as we know it. 4. These conditions make it impossible for Earth-like plants, animals, and humans to survive on Jupiter. Final answer: It is not possible for plants, animals, and humans to live on Jupiter because it lacks a solid surface and has extreme atmospheric conditions unsuitable for life.
