Answer:
Option (B) is the correct answer of the following question.
Explanation:
Collagens are a family of enzymes that perpetuate and protect many of the body's tissues, with the exception of connective tissue, femur, fibula, pigmentation, and the caucasian eye (optic disc). It would be the best choice on which to base the phylogeny.
- The first and most concentrated substance in the body is the collagen genes.
- It is a large, indigestible cellular muscle which maintains organisms and gives internal cells a texture.
- Collagen is also an essential part of the crisscrossing membrane neurons. 
Other options are incorrect because they are not related to the given scenario.

Answer:
b: 8;8
Explanation:
Mitotic or meiotic cell division constitute the m phase of the cell cycle. At the end of the m phase, the new cells enter the interphase stage of the cell cycle. The interphase is further sub-divided into;
- <em>the  phase,</em> phase,</em>
- <em>the  phase,</em> phase,</em>
- <em>the S phase; and</em>
- <em>the  phase</em>. phase</em>.
The  phase is essentially a resting phase. Cells that do not need to divide except when necessary move into this phase after exiting the m phase.
 phase is essentially a resting phase. Cells that do not need to divide except when necessary move into this phase after exiting the m phase.
Actively dividing cells enter the  phase after exiting the m phase. Cell development and growth takes place. From there, the cells enter the S phase where DNA replication/synthesis takes place. The cells then enter the

 phase where proteins are synthesized in preparation for division or m phase.
At the S phase, the amount of DNA a cell carries is doubled but the chromosome number remains the same. For example, if a cell enters the S phase with 2 g of DNA containing 10 chromosomes, at the end of S phase, the amount of DNA would have come 4 g while the number of chromosomes will remain 10.
Hence, if the average amount of DNA in the assayed cells immediately after mitosis is 4 picograms, the amount would be 8 picograms at the end of S phase and will still remains 8 picograms at the end of  phase.
 phase.
The correct option is b.
