A. All distant galaxies are moving away from us.
Starements that are guaranteed to be true are called facts
1. two copies of the duplicated chromosome are attached at their centromeres before separating
2. chromosomes replicate before cell division
3. chromosome separation begins at the origin of replication on DNA
4. Before separation duplicated chromosomes condense; nuclear envelope fragments permitting chromosome separation
5. replicated chromosomes separate by attaching to some other structural feature of the cell
Explanation:
In the given question, the DNA replication steps of both prokaryotes and eukaryotes are provided in which some are common to both eukaryotes and prokaryotes and some are unique to the prokaryotes and eukaryotes.
<u>Eukaryotes
</u>
1. Option-4 as the nuclear envelope is present in eukaryotes only.
2. Option-1 as centromere allows the kinetochores bind to the centromere which separates the chromosome.
<u>Bacteria
</u>
1. Option-3 as DNA replication process separates the strand of the DNA.
<u>Both
</u>
1. Option-5 as the chromosomes separate by other structures like microtubules
2. Option-2 as genetic material to be passed on to the generation must be replicated.
Answer:
c. Aa Bb
Explanation:
The parents were pure breeding with genotypes AAbb and aaBB. A cross between AAbb and aaBB would produce AaBb genotypes in F1 progeny. Two F1 strains would be crossed to produce F2 progeny. The F2 progeny would have the genotype ratio= 1:2:1:2:4:2:1:2:1.
Out of all the obtained genotypes in the F2 generation, the proportion of "AaBb" genotype was 4/16. Therefore, "4" in the given ratio represents the genotype "AaBb".
Answer:
They are both animals and both are mammals. I think that is what you mean.
