Answer:
The four elements are oxygen, hydrogen, carbon, nitrogen.
So it will be O A.N2.
Explanation:
They are versatile elements, capable of producing a vast array of chemical compounds, but it also has to do with the fact that they are among the most abundant elements in the universe.
Sexual reproduction allows some of the genetic information from each parent to mix, producing offspring that resemble their parents but are not identical to them. In this way, sexual reproduction leads to variety in the offspring. Animals and plants can reproduce using sexual reproduction.
Hope this helps. :)
Establishing just one tree species can impair soil fertility and prevent other species from being established.
We can arrive at this answer because:
- Ecological succession is the term that refers to the establishment and development of plant species in areas that were devastated until that area presents a large vegetative population when it reaches climax.
- During the establishment of ecological succession, the must be a great diversity of plants, allowing for harmony and balance between the species and the environment.
- When ecological succession is done with only one species, this balance is impaired, as well as ecological succession.
This is because a single tree species can hide soil fertility and make it unsuitable for planting any other species. In addition, the genetic unity among plants makes it easier to develop pests and diseases that can devastate the region.

Bacteriophages like other viruses, consist primarily of a protein coat and ackaged DNA. Description on the function of critical enzyme; DNA helicase unwinds its two strands and makes a replication fork. The enzyme primase puts down a short RNA strand complementary to a short sequence of DNA being replicated to initiate a new strand of DNA. DNA polymerase elongates the new strand of DNA, building a new anti-parallel strand.
