Answer:
Misha
Explanation:
Archie, Soledad and Sam are right about the types forces, but not how many. Misha is the only one who says there are multiple. Tess is just wrong.
The question is incomplete as it does not have the options which has been provided in the attachment.
Answer:
Option-3 and 4
Explanation:
In the given question, the table of the different nitrogen bases of a different organism has been provided in which the number of bases has been mentioned.
In the table, the amount of thymine is almost similar or equal to the adenine while the number of guanines almost equal to the cytosine for a particular species. This data follows the Chargaff postulates which state that adenine bind thymine and cytosine bind guanine therefore the number of complementary bases will be equal.
Thus, Option-3 and 4 are correct.
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
