It has been a while since biology...but if there is one thing I definitely remember, it is the replication process of DNA.
Once the cell is ready to commence the process of replication, it begins by unzipping the double helix. This task is completed by an enzyme called the DNA Helicase. Then a DNA Polymerase takes half of the unzipped DNA strand and creates corresponding deoxyribonucleotides.
Hope I could help! Have a good one.
After first exposure to an antigen, it can take about three weeks for antibodies to reach a detectable level. The body will react to disease by creating antibodies and testing their effectiveness against the unknown antigen.
Antibodies are the body's way of fighting off foreign threats. Also known as immunoglobulin, they detect and attack pathogenic bacteria and viruses. These antibodies detect a protein that is unique to the surface of the pathogen called the antigen.
At times, we can see an increase in antibodies for one disease, for example, <em>Lyme disease</em>, in the presence of <em><u>non-Lyme disease antigens.</u></em> This is often due to antigenic variation, which is a method used by pathogens to mask their respective antigens. There are also general use antibodies that will increase in reaction to any pathogen.
As with any illness, a patient who receives treatment sooner will fare better than those whose treatment is delayed. This is due to the fact that earlier treatment with antibiotics will allow the body to fight off the infection before the bacteria can reproduce further.
After the first immune response, antigen-specific antibodies will remain for some time to provide the body with "immunity" to the pathogen, while <u>general-purpose antibodies will return to a base value. </u>

Answer:
A. Layer A is the troposphere and Layer B is thermosphere
Explanation:
The troposphere is the lowest layer of the atmosphere. THis is where all life life resides and where weather occurs as well. It contains the air we breathe. As we go higher in the troposphere, the temperature goes down.
The thermosphere is part of our atmosphere but it is very high up and considered to be part of outerspace as well. It is heated up by the UV rays and X-rays that it absorbs.
