A vaccine puts into the body weakened/dead pathogenic material, which by itself is incapable of causing disease. How does this help to protect the body in the case of infection by a live pathogen?

Answers

During the process of vaccination, an attenuated pathogen is inserted into the body the organisms. The attenuated pathogen is able to provoke the primary immune response in the body of the organism without causing any harm.

Once the primary immune response is generated, the body creates a memory in form of antibody to the pathogen. After vaccination, if the pathogen infects, the body recalls the memory and generates a secondary immune response. The intensity of the secondary immune response is much higher than the primary one, so, as soon as the pathogen enter in the body, the antibodies against it are activated and result in defeating the infection.

For a better understanding purpose, the intensity of the primary and the secondary immune response is given in the figure:

Answer:

d.  a vaccine causes the secretion of antibodies which remain in blood and fight the pathogen at the time of an infection.

During which process is mRNA synthesized from a DNA template with the aid of RNA polymerase? A.transcription B.translation C.translocation D.transportation

Answers

Transcription is the process in which mRNA is synthesized from a DNA template with the aid of RNA polymerase. Translation, translocation and transportation are separate processes. 

Answer;

-Transcription;

Explanation;

-Gene expression involves the process of transcription and that of translation.

-Transcription, which takes place in the nucleus of a cell, involves the synthesis of a messenger RNA (mRNA) from a DNA template. The process is catalyzed by the enyzme RNA polymerase.

-The mRNA synthesiszed from transcription then undergoes the process of translation outside the nucleus (cytoplasm) to form proteins, that may be used for various cellular functions such as regulating cellular reactions.

In Hawaii, new land forms when lava erupts from Kīlauea volcano and hardens. The new land is without any living things. The first organisms to populate the surface of that new land are known as species. With time, a series of changes called succession occur on the new land through which it becomes colonized by a variety of organisms.
