Sperm cells are stored an matured in the Epididymis
Answer and Explanation:
Observing population directly gives you accurate result .
Direct observation does not need any intermediary as they themselves go for survey.
So, it is cost efficient.
Whereas indirect observing may involve manipulations.
It requires someone or many to hire who helps in surveying.
It incurs cost.
Thus, direct observation is always better than indirect observation.

Explanation:
Each eukaryotic chromosome usually has repeated telomere sequences ranging from 2 to as many as 2000.
There is normally just one specialized DNA sequence called the centromere per eukaryotic chromosomal DNA molecule.
The origin of replication is the site where DNA duplication starts in S phase.
The centromere attaches the chromosome to the mitotic spindle via the kinetochore structure.
Teleomere contains repeateted sequences at the ends of the chromosomes.
The pelagic zone is where plankton can be found most frequently.
Plankton is chlorophyll-containing photosynthesizing plants that make their own sustenance from carbon dioxide and sunlight.
They are autotrophic aquatic plants. Their roots have a good aquatic life adaptation.
Thus, the pelagic zone is where plankton is most frequently found.

Answer:
Explanation:
My best bet is DNA methylation at the site of Tweedledum's leptin gene or Histone Acetylation at the site of Tweedledee's gene.
B/c DNA methylation is a process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription. So this is probably repressing Tweedledum's leptin gene trancription which is not happening in Tweedledee.
Additionally, Histone Acetylation at site of Tweedledee's gene increases her trancription b/c Histone acetylation causes DNA to be more accessible and leads to more transcription factors being able to reach the DNA. Thus, acetylation of histones is known to increase the expression of genes through transcription activation.
