Why must cells be able to both transcribe and replicate their DNA? (2 points)
Artemon [7]

Transcription is a process, which includes copying of the genetic formation from DNA into mRNA ( messenger RNA). This provides instructions for the synthesis of specific proteins.

Which characteristic is used to classify galaxies?
Brut [27]
<h2>Answer:</h2>

The galaxies were classified based on the shape and structure exhibited by them.

<h2>Explanation:</h2>

In the 1920's, the galaxies were classified based upon the shape and structure by famous scientist Edwin Hubble. He did it by a telescope with which he captured various galaxies existing. He ordered (or "arranged") their shapes as winding, banned winding, curved, sporadic, and impossible to miss. This framework was known as the Hubble morphological succession of cosmic system types.  

Hubble noticed that a few universes, similar to the M31-Andromeda Galaxy, showed up as circles and had arms of stars and residue which showed up in a winding example. Like M31, these worlds showed up almost uniform in splendor. Likewise, Hubble saw that in a portion of these sorts of worlds the arms were all the more firmly twisted around the cosmic system. He called these winding systems. Our Galaxy, the Milky Way, is a case of a winding universe.

sladkih [1.3K]
D. Dominant

It is dominant as...
The white coat alleles are recessive, meaning the black coat would most likely be dominant alleles. Assuming the black coated dog had the alleles of BB, and the white coated dog had the alleles ww, there would be a 100% chance that the offspring would have Bw alleles, where the black coat is dominant, "all the offspring were black". 
B = Black, W = White
      B    B
w   Bw  Bw
w   Bw  Bw
The diagram above shows that the offspring would be 100% black coated.

Not sure if you wanted an explanation, but I tried.
