Straight chain, branched chain, and ring
Answer:
Molecules of gas starts movement when they get energy from the sun in the form of heat.
Explanation:
Molecules of gas absorbed heat energy coming from sun. This heat energy is converted into kinetic energy due to which gas molecule moves faster. Volume of gas molecules also increases due to expansion of molecules by the absorption of heat energy. So more space is occupied by gas molecule as compared to liquid molecules.
Answer: prokaryotic cells
Explanation:
A prokaryotic cell is a cell without a nucleus. Since this is a simple definition I cannot explain much further, but an example of a prokaryotic cell is bacteria.
There are many lines of evidence which clearly show that the atmospheric CO2<span>increase is caused by humans. The clearest of these is simple accounting - humans are emitting CO2 at a rate twice as fast as the atmospheric increase (natural sinks are absorbing the other half). There is no question whatsoever that the CO2 increase is human-caused. This is settled science.</span>
