Answer: The Andromeda galaxy
Explanation:
And that's going to happen someday! The Andromeda galaxy is currently racing toward our Milky Way at a speed of about 70 miles (110 km) per second. Ultimately, the two galaxies will collide and merge.
Rumen, reticulum, omasum, and abomasum
Cellular respiration allows carbon to enter water, that is a process that allows cells to get energy from nutrients.
Answer:
a. All of these statements are true
Explanation:
The fovea is a region of the retina that’s densely packed with cones, a type of photoreceptor (a cell that detects light). The other type of photoreceptor is the rod.
While <u>rods function at low light levels</u> and allow night vision, they can’t distinguish color. In contrast, <u>cones function at high light levels and provide color vision</u>.
That's why you can't perfectly distinguish colors in a dark place.
Exons are the DNA fragments that get to be transcripted and translated into proteins. Option b)<u> </u><u>Exons</u> end up being expressed in the protein.
<h3>What are introns and exons?</h3>
Even though more than 70% of the DNA is related to genes, just a part of the genes is translated to proteins. Most genes have DNA segments that are not transcripted or translated intercalated with segments that are translated.
- Introns are non-encoding sequences that produce interruptions in a eukaryotic gene.
- Exons are the encoding sequences. Exons are the nucleotidic sequences that do codify proteins.
Most of the eukaryotic, multicellular genes contain introns in their sequences, intercalated with exons.
Introns are transcripted to mRNA molecules and get excised before translation by a specific mechanism. This occurs before the mRNA leaves the nucleus. The introns are excised and the exons must splice to form a unique molecule. This process is known as splicing.
Exonic sequences are the fragments that are transcripted and translated into proteins.
The correct option is b). Exons end up being expressed in the protein
