The right answer is: <span>phagocytosis of foreign materials</span>
The cell 1 is a microglial cell
Microglia are a set of microglial cells, which make up a quarter of the cells of the central nervous system.They have a star shape, are small and can move. Related to macrophages (it has the same morphology and does the same function as phagocytosis of antigens), their role is to ensure the immunity of the nervous system.
Answer: Saline = Solution, Salt = Solute and Water = Solvent.

The answer which is false is, gene flow leads to divergence and the formation of new species.
What is speciation?
For speciation to occur two populations must be prevented from interbreeding.
This means that populations must become isolated from on another through the geographical or biological barriers.
If populations remain isolated long enough, speciation will eventually occur because of changes accumulated in population due to natural selection.
What is gene flow?
Geographical isolation hampers gene flow because of spatial separation which in turn leads of reproductive isolation due to the inability of meeting gametes to leads.
It causes genetic drift due to the barrier of gene flow between them and parent species.
Certain alleles get fixed into population due to inbreeding in a smaller population while other gets eliminated, this leads to formation of new alleles and new gene pool, so-called progressive genetic divergence.
Finally there is the formation of new species when genetic variation are accumulated for several generations.

An autotroph is a living organism that produces complex compounds such as carbohydrates, fats and proteins. They are producers in a food chain, in contrast to heterotrophs who are consumers.
