<span>The primary distinction is that eukaryotic cells have a "true" nucleus containing their DNA, whereas prokaryotic cells do not have a nucleus. Both eukaryotes and prokaryotes contain large RNA/protein structures called ribosomes, which produce protein. Prokaryotic cells are usually much smaller than eukaryotic cells. Therefore, prokaryotes have a larger surface-area-to-volume ratio, giving them a higher metabolic rate, a higher growth rate, and as a consequence, a shorter generation time than eukaryotes.</span>
Answer:
With the development of industry (finally followed by the accelerated connection of settlements), more and more emissions of various gases into the atmosphere began.
Explanation:
Gases, ie particles on which the solar radiation (at least its infrared part) is efficiently dissipated and according to a larger published mechanism additionally warms the planet.
A large number of other gases, such as carbon monoxide and methane, are also taking up more and more space in the air, thus increasing the warming effect of the planet.
These gases do not only destroy the atmosphere directly. Between 30% and 40% of carbon dioxide (and the percentage of others) dissolves in the oceans. This mechanism reduces the pH value of water or increases the acidity.
