Desoxyribonucleic acid synthesis occurs just prior to cadre segmentation through a process called retort . When replication begins the two string of DNA are separated by a mixed bag of enzyme . Prior to cell division, the DNA cloth in the original cell must be duplicated so that after cell division, each new cell contains the full amount of DNA material.
A) genetic drift

<span>DNA Paternity Testing is the most advanced and accurate method available for resolving parentage for medical, legal, or personal reasons.
Turnaround Time: With advanced DNA technology, paternity testing is accurate, rapid and affordable. Paternity can now be determined 3 to 5 business days after the samples arrive at the laboratory. Results are released immediately once the testing is completed.
Description: During a DNA paternity test, a buccal swab (mouth swab) specimen is collected from the child and the alleged father. Testing the mother is optional. The sample which is collected contains cells, and most of the cells in our body contain a full set of genetic information in the form of DNA (deoxyribonucleic acid). A person's DNA represents a "genetic blueprint" and like a fingerprint, is unique to each individual. At the laboratory, the DNA is extracted from the cell and specific regions of the DNA are amplified by a process known as PCR (polymerase chain reaction) for careful examination. The DNA pattern of the child is compared to that of the alleged father. Because the genetic information of a child is inherited from his/her biological parents, examination of the DNA of the child will conclusively determine whether the alleged father is the true biological father of the child.
Who should consider the Private Test option? The private home test kit option is suitable for individuals who wish to find out the truth about paternity before deciding on the next step. If a private test is ordered, a buccal swab (mouth) swab DNA kit is sent directly to the parties involved in the test for sample collection. The sample collection process is quick, easy and discreet and takes just minutes to complete. Once the laboratory receives the samples, testing is completed within 3 to 5 business days.</span>
Answer:
See the answer below
Explanation:
In science, research questions are generally derived from the observation of phenomena. Also, hypotheses that represent general statements that have not been tested are formulated in such a way that they can be falsified. Hence, for each of the observations in the illustration, the question and their respective hypothesis would be as follows:
1. Observation: a teenager observed that he had three new pimples the night after eating a chocolate bar.
Question: Do chocolate bars cause pimples in teenagers?
Hypothesis: If teenagers eat chocolate bars, they might get pimples.
2. See the attached image
3. Observation: A little boy observed the leaves on trees changed colors when the temperature was lower.
Question: Do lower temperatures cause tree leaves to change color?
Hypothesis: If the ambient temperatures of trees are lowered, their leaves might change color.
