Explanation:
2. distribution and abundance of organisms
3. speciation of plants
4. Antarctic convergence
Geographical isolation is the physical barrier dividing the communities. It usually stops the gene flow between species in a process called allopatric speciation, contributing to reproductive isolation.
Further Explanation:
Spontaneous modifications within the genome may arise during the cycle of cell division, called mutations. These errors occur as copies of the DNA are produced within the cell; mutations may range from small modifications, called single nucleotide polymorphisms, to large-scale deletions and multi-gene additions.
These mutations form variants which, within a population, become stable, resulting in the formation of separate, genetically distinct populations called species. Apart from allopatric speciation, new species arise through several other evolutionary mechanisms such as:
- peripatric speciation— like allopatric speciation, however, one group is much smaller, making the unique characteristics more notable, or distinct
- parapatric speciation— sub-populations in a large geographic region develop reproductive isolation by mating with those nearby, but continue to undergo reproductive isolation;
- sympatric speciation-absence of physical barriers that impede the passage of genes; reproductive segregation by many variants of the same genes called polymorphisms

The correct answer is C) Wood burning. Hope this helps.
Answer:
d. occur in the same place, the cytoplasm
Two diverse species naturally breed an offspring, and selective preserves raver new traits in a given environment, (they evolve).

Answer:
so many dust particles are there in the air. during inhalation, those particles fail to reach our lungs due to the presence of ciliated mucous lining in our upper respiratory tract.
primarily nose and its ciliated mucous lining and nasal hair prevent the dust particle to come inside. if some particles get entry then the person starts sneezing until those particles are out.
if the nose fails to prevent the dust then our respiratory tract does it.
