Answer:
Question 1 - c. vv
Question 2 - b. Any of the non-sex chromosomes
Question 3 - b. Eukaryotic
Explanation:
Question 1
As explained, the gene for normal wings (V) is a dominant gene while the gene for the vestigial wings (v) is recessive. Dominant genes overpower any recessive genes.
VV - Two dominant genes will produce the dominant trait
Vv - The dominant gene (V) overpowers the recessive gene (v) and produced the dominant trait.
This means that the only way to have a fly with vestigial wings is if the fly has 2 recessive genes. This means that our answer is c. vv
Question 2
An autosome is defined as any of the non-sex chromosomes.
Question 3
Linear chromosomes are a type of chromosome most often found in eukaryotic cells. On the other hand, prokaryotic cells usually have circular chromosomes. This means that our answer is b. eukaryotic

Answer:
The enzyme Topoisomerase functions to prevent super-coiling of the DNA molecule during replication.
Explanation:
- During replication, topoisomerases are required to relieve the positive supercoiling that arises from DNA unwiding mediated by Helicases.
- A DNA topoisomerase is a nuclease that breaks a phosphodiester bond in a DNA strand.
- All topoiomereases are classified as Topoisomerase I and Topoisomerase II depending on whether they cleave one or two strands respectively.
- Topoisomerase I do not use ATP as a source of energy, the reaction is powered by energy stored in super-coiled DNA.
- Topoisomerase II also do not require external energy but it utilizes ATP hydrolysis to drive conformation changes in the protein during reaction cycle.
The first step is The replication fork forms (d)
Answer:
down
Explanation:
because gravity come from the center of the earth the gravitational pull, pulls us down.
