Unfortunately no, my friend is not correct. The CO2 pollutants leaving his exhaust are warm, yes, but that is why our atmosphere is creating global warming which is affecting climate in all regions. When there is more people that means more cars and more pollutants being dispersed into our atmosphere.

Hey there! :D
Organization in organisms is like this: 
cells => tissues => organs => organ systems => organisms 
Since we are talking about a group of cells, this would be a tissue. Don't let the word 'function' confuse you. Tissues do functions as well as an entire organ or organ system. 
It is helpful to use the flow chart when asked questions like these, so make sure to memorize it! It will be helpful in any level of science. 
I hope this helps!

The population age structure is is simply the structure of a population in a given time period by age groups. In order to represent the population age structure in a simple and efficient way, the population pyramid is used. Depending of what type of population is dominant, the pyramid will have different shapes. It can easily show us the trends and type of demographic transition for a particular population. When there high birthrates, the pyramid tends to be widest at the bottom, but when there's low birthrates the pyramid tends to be widening in the middle and upper sections.
