Which statement accurately describes dark matter? It is the same as dark energy. It is well understood by scientists. It does no
kow [346]

Answer:

Dark matter does not emit electromagnetic radiation.

Explanation:

Dark matter comparative to dark energy, has various differences. You could say that dark energy is put into action on a larger scale than dark matter, which is also why dark energy makes up 74 percent of the universe. Thus, dark matter ≠ dark energy.

Scientists have a lot to learn about dark matter, so we can't claim that this subject has been well understood about scientists. In fact, it is one of the least understood parts of the universe!

_______________________________________________________

Now dark matter can be defined as particles that do not absorb, reflect, or emit light. Thus, it can't be observed by electromagnetic radiation - nor shifts in red and blue light. At the same time it does not emit electromagnetic radiation.

DNA polymerase is an enzyme which carries out all forms of DNA replication. This enzyme catalyses the addition of nucleotide substrates to DNA in the 5' -3' direction during replication. Proof reading and error correction is done by the DNA polymerase. This enzyme can remove nucleotides from the end of the growing strand in order to correct mismatched bases.

Why did the movement of plants to land lead to adaptive radiation?
spin [16.1K]

Answer: Adaptive radiation refers to the ability of living organisms to evolve rapidly from an ancestral forms into variety of other forms especially when the organisms move into a new environment that has abundant resources. The resources, which are present abundantly in the environment allow the living organisms to spread out in the environment and to find different habitats in the environments that favour their survival.In the question given above, adaptive radiation allows plants to fill different habitats (niches) that are found on land and to spread out rapidly.

Hope this helps :)
