Fossils are Remains Of Tracers Of Prehistoric Life
Scientists have concluded that the average human body contains approx. 37.2 trillion cells. However it depends upon your size compared an average human being. :)<span />
It shows the "rank" of the organism is not a characteristic of the cladistics system. Showing the probable sequence of origins, and showing shared derived characteristics are characteristics of the cladistics system.
I'm pretty sure the answer is B. Invest in alternative energy sources that do not burn fossil fuels. The reason I would pick B is because in Antarctica the ice is melting more and more over time because, cars and factors etc are burning fuels which result in more damage to the ozone layer.
