Answer:Abbreviations Rubisco
Explanation:
C. They unwinds the two strand of DNA.
Answer:
b. the new species must be unable to breed with the original species.
Explanation:
By definition, species are defined as groups of similar organisms that can live and breed freely. This means that individuals in that species can interbreed and produce viable, fertile offspring. However, two different species cannot interbreed to produce fertile offspring due to biological barriers known as mechanisms of reproduction isolation.
These barriers are broadly classified as pre and postzygotic. Prezygotic barriers include the following:
- Habitat isolation: Two species occupy entirely different and distant habitats.
- Temporal isolation: Two species procreate at different times of the year.
- Behavioral isolation: Two species exhibit different mating behaviors.
- Gametic isolation: The gametes of the two species cannot fertilize.
- Mechanical isolation
Speciation, the production of an entirely new species, requires a maintenance of genetic diversity. Therefore, the new and original species cannot interbreed as this would limit the gene pool and decrease genetic variations.
Answer:
Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment. This double layer consists largely of specialized lipids called phospholipids.
Cells are separated from the IF by a selectively permeable cell membrane that helps regulate the passage of materials between the IF and the interior of the cell. The body has other water-based ECF.
