Answer: Option a
Explanation:
Biotechnology is the branch which deals with the most advanced techniques which is required to make the life easy.
One of the most important application is Genetically modified crops. Genetically modified crops are pest resistant and have many advantages.
There are few disadvantages one of them is beneficial insects are also adversely affected. There are many useful insects that helps in pollination and they are also killed because of pest resistant plant.
hence the correct answer is option A

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:
D. Cell
Explanation:
Cells are the structural and functional unit of life. Cells are made up of various organelles, the liquid cytosol and nucleus in the case of eukaryotic cells. Biomolecules such as carbohydrates, lipids, proteins, etc. form various cell organelles. However, cells have level has emergent properties, the features that are not found at lower levels. For instance, cells are able to perform the life processes and distinguish the living things from non-living ones.
