The group of lipids that represents the general structure of most steroids would be provided in option A. Notable ring type of structures that are fused and may or may not display certain functional groups that can provide different functions to this steroid depending on the functional groups present.
The regulation of the bodies internal environment is called homeostasis. And there are so many ways that affect homeostasis in the human body and to name three: first is the heat where we seat when we get too hot. Second, is the cold where we shiver when we get too cold and the third is the fluid intake where dehydration can kill.
Climate change happens by the circle of life
The best evidence of such phenomena could be a population's genetic variation decrease.
When a population bottleneck occur it means that for some reason (i.e. environmental events) the size of a population is largely reduced. This leads to reduction of the genetic variation in that new smaller population. When a bottleneck occur, the founder effect is normally seen, which is that one population is established by a small group of a previously larger population leading once again the genetic variation, now though with a bigger population, to be very reduced.
The correct option is C.
Both DNA and RNA are made up of four nitrogenous bases. The nitrogenous bases that are found in DNA are adenine, guanine, cytosine and thymine. The nitrogenous bases that are found in RNA are adenine, guanine, cytosine and uracil.
