Question

Даю 60 баллов! Могут ли в настоящее время образовываться органические вещества из неорганических веществ так же, как 4 млрд. лет тому назад? Ответ обоснуйте!

Answer 1

Да могут

1) сначала из неорганических веществ возникли простые органические соединения — аминокислоты, углеводы и т.д.,
2) затем образовались биологические полимеры,
3) следующим этапом было образование первичных организмов, отграниченных от окружающей среды мембранами.

Answer 2

Да например Cac2+2h2o=c2h2+Ca(oh)2

Answer 3

Can organic substances form from inorganic substances in the present time as they did 4 billion years ago? Please explain your answer.

The question of whether organic substances can form from inorganic substances in the present time, as they did 4 billion years ago, is an interesting one. However, it is important to note that the origin of life and the exact processes by which organic molecules formed on Earth are still subjects of scientific investigation and debate. While there is evidence to suggest that organic molecules can form from inorganic substances under certain conditions, the exact mechanisms and conditions required for the formation of life are not yet fully understood.

One of the key experiments that demonstrated the possibility of organic molecule formation from inorganic substances is the Miller-Urey experiment conducted in the 1950s. In this experiment, Stanley Miller and Harold Urey simulated the conditions of early Earth by creating an atmosphere containing gases such as methane, ammonia, and water vapor, and subjecting it to electrical discharges to simulate lightning. The experiment produced a variety of organic compounds, including amino acids, which are the building blocks of proteins.

Since the Miller-Urey experiment, numerous other studies and experiments have been conducted to investigate the formation of organic molecules under different conditions. These studies have shown that organic molecules can form in a variety of environments, including deep-sea hydrothermal vents, volcanic environments, and even in space These findings suggest that the formation of organic molecules from inorganic substances is a plausible process that can occur under certain conditions.

However, it is important to note that the formation of organic molecules is just one step in the origin of life. The transition from simple organic molecules to self-replicating, complex organisms is a complex and still poorly understood process. Many factors, such as the availability of energy sources, the presence of suitable environments, and the interaction of molecules with minerals and other catalysts, likely played a role in the development of life on Earth.

In conclusion, while there is evidence to suggest that organic substances can form from inorganic substances under certain conditions, the exact mechanisms and conditions required for the formation of life are still subjects of scientific investigation. The origin of life is a complex and fascinating topic that continues to be studied by scientists around the world.
