Answer:
Prokaryotes and Eukaryotes are two types of cells with similarities and differences. Eukaryotes are plant cells and animal cells. They are mostly found in multi-cellular organisms. Prokaryotes are usually single-celled organisms and have a tail. Those are the examples that I remember, but there are way more similarities and differences. I hope this helped!!

Yes, human activities are a significant cause of the increase in the amount of Carbon dioxide in the atmosphere.
<h3><u>
Explanation:</u></h3>
The increasing amount of 
is a big problem in today's world for the atmosphere. Human activities are playing a vital role in the rise in . Carbon emission is majorly happening because of pollution.

All these activities are leading towards global warming, which one day will bring our earth to an end. So it is imperative to take some severe legal measures to save the environment and decline the amount of producing.
