Answer:
through glacial deposits and ice cores
Explanation:
Answer:
it is expected to observe two bands: one band of light density and one band of heavy density
Explanation:
DNA replication is semiconservative because when DNA is replicated both resulting DNA molecules are composed of one original strand and one newly synthesized strand. If DNA replication would be conservative, then the original DNA molecule would serve as a template to produce a new DNA molecule, thereby each cell division would produce one daughter cell with a new DNA molecule and one daughter cell with the original DNA molecule of the parental cell. In this case, the transfer of bacteria-like organisms into a heavy 15N medium would produce two types of DNA cells after replication: cells with original DNA of light density (14N) and cells with new DNA of heavy density (15N), which would be distributed in two bands after centrifugation.
Proteasomes are a large protein complex present in all eukaryotic cells that break down protein.
<h3>What are proteasomes?</h3>
It is considered one of the main pathways involved in the processes of enzymatic protein degradation.
It is the group of proteins that are associated forming large complexes, whose function is to digest cytoplasmic proteins, generating peptides.
Therefore, we can conclude that proteasomes is a large protein complex present in all eukaryotic cells that breaks down protein .

Answer:
The geocentric model says that the earth is at the center of the cosmos or universe, and the planets, the sun and the moon, and the stars circles around it. The early heliocentric models consider the sun as the center, and the planets revolve around the sun.
