Answer:
b. AMHT
Explanation:
The arrangement of genes on a chromosome can be estimated by considering the distance between the genes using the rate or frequency of their cross overs. Therefore, we have:
A-------------------18-------------------T
M---------9---------
--------------11-------------H
---2---
Thus, using the arrangement above by selecting the letters as they occur, we have:
AMHT as the correct genes arrangement in the chromosome.
Answer:
Flu vaccinations are fundamental as they reduce the risk of flu illness by over 50%.
Explanation:
Flu vaccinations reduce the risk of flu illness by over 50%. This makes this process extremely important and fundamental for all human beings as they not only protect the person who gets the vaccine, but it also contributes to the prevention of spreading to other people, especially children and older adults who possess a greater risk of developing flu complications.
The antibodies that are produced by the vaccine prevent the flu virus from attaching to a healthy cell. However, if a person has not been vaccinated, the virus will attack the healthy cells because there is an absence of antibodies that prevent this process.
Answer:
There is no short answer.
Explanation:
Athletes such as runners may prefer to train at higher altitudes than the altitude they perform at. This is because the higher altitude increases the number of red blood cells in the athletes body thus providing the muscles with more oxygen which increases performance.
If the runner moves from Nebraska to Colorado which is at a higher altitude, she will see an increase to her aerobic performance in the first three months.
I hope this answer helps.
Answer:
Three theoretical models for the replication of DNA had been proposed in the past. Out of these, the method of semi-conservative replication is most widely accepted.
Conservative replication: In this method, no DNA unwinding takes place. The parent DNA gives rise to daughter DNA.
Dispersive Method: In this method, the chains in the DNA molecule break and recombination occurs randomly. The daughter and parent strands will have segments of recombinant DNA.
Semi- conservative: In this method, the two strands of the double helix unwind. Each strand acts as a template for the synthesis of a new strand.
DNA replication is more complex in eukaryotes as compared to prokaryotes. Prokaryotes have a single point of origin from where the replication begins. Eukaryotes have multiple points of origin. Eukaryotic cells have a unidirectional method of replication whereas prokaryotes do not. Prokaryotes just have two polymerases whereas eukaryotes have more than four. The replication rate is faster in prokaryotes.
