Answer:
C
Explanation:
Complication to Phylogenetic inference is most likely to be widespread in a group of species that have undergone an evolutionary radiation because of Great variability of the rates of molecular evolution Incomplete lineage sorting.
Incomplete lineage sorting: It is a characteristic Phylogenetic analysis where trees produced from single gene differ from population or species level tree.
option c is correct.
Answer:
Explanation:
Diagnosis - A disease must be diagnose this can be done by group of expertise. They diagnose one to two persons with the disease asking them questions about their state of health, how they were expose to the illness. This enable them have enough evidence as regarding the disease.

Explanation:
Answer
Complex barrier to the flow of substances out of the cells,and restrictions to inflow of unwanted substances into the cells. The hydrophobic and hydrophilic nature of the cell membrane controls the entry of substances from the extracellular medium into the intracellualr. In addition the polarity restricts certain substance movement across the walls.
Serve as the selective channels for the influx of certain substances into the cells, and the out flux of wastes.This is through ion channels for the movements of ions across.
Provide insulation to the cells,to maintain the constant internal temperature,this is through the presence of lipids as( Phospholipids and cholesterol).The latter prevent the clogging of the lipids in the cell membrane therefore preventing frozen up of the cell membrane,providing insulation.
Separation of metabolic process in the cell.
Explanation:
Cell membrane-This is present in all cells.But the variation of its constituents makes it unique to each cell. Although it performs the same role, the location and role the cells it bounded, reflects its constituents, it is made up of lipids, carbohydrate, protein and cholesterol
