Protocells are beloved to represent the initial form of life because they exhibit which of the following living properties ? ( choose all that apply )
1.) metabolism
2.) reproduction
3.) growth
4.) photosynthesis
5.) multicellular

      The right options to answer to this question are options 1. Metabolism, 2. Reproduction and 3. Growth

      What we need to pay attention right here is to the question actually, so, it asks you about the initial form of life, it's well known that the first cells of the world were unicellular cells, by this way, we can remove the last option from our list, now we stand with 4.

      The fourth one says something about photosynthesis, but think about it, is it possible for the first cell to be able to do this process, yes, it is, there are two different hypothesis to explain this matter, in the way I'm answering it, I'm not considering this option.

      Well, the other 3 say about growth, cells need to grow up to adapt themselves to the environment, reprodution, they need to be able to multiply themselves to maintain their genes to the next generation, and the metabolism, the cell needs that to work properly, even though it's a protocell.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
