Acquired immunity is the type of immunity that exists when a person is exposed to an antigen and subsequently makes antibodies against the antigen.

Immunity is the defense mechanism of the nervous system to avoid pathogens affecting the body and making it sick. There are two major types of immunity: innate and acquired. Innate immunity is the kind of immunity present in the human body by birth. Whereas, acquired immunity is gained over time.

Acquired immunity specifically promotes the antibodies or lymphocytes to inhibit the action of pathogens when it encounters one. It is further categorized into two types: active and passive immunity.

Active immunity indulges in the primary response to a pathogen. It produces antibodies to fight against it and preserves some to fight against the same pathogen encountered for the second time. Passive immunity, in addition, involves the medications prescribed to enhance immunity.

Which of the following activities will help make rural societies more sustainable? A. Design energy efficient forms of transport

denpristay [2]

Answer:

The correct answer would be Option C, Multipurpose Trees.

Explanation:

With the advancement in industries and other areas of technology, the rural areas have become so much polluted. So the sustainability of the rural areas is doubtful. The air in the rural areas have become polluted and needs measures to prevent it from harmful consequences of the industrial advancements. Along with industries, the air pollution is also added through vehicles discharge, waste disposal, etc also contribute towards the non sustainability of the rural areas. So to overcome all these problems, the best solution is to grow the multipurpose trees in the rural areas as much as possible to increase the sustainability of these areas. With the plantation of trees, the problem of pollution will be controlled and thus make these areas sustainable.

if a retrovirus could infect one of any of these kinds of cells, which would amplify it the most within the first 2 hours?

ryzh [129]

Cancer cells are the best target to amplify the most within first 2 hours. Highly oncogenic retroviruses are recombinants of viral and host genes.

Retroviruses are viruses with RNA rather than DNA in their genomes that infect cancer cells. Reverse transcriptase is an enzyme that is used to integrate into the DNA of the host cells. It is enhanced to a greater extent the more cell replication takes place. More retroviruses are then produced by the cell, infecting further cells. Many diseases, including AIDS and various types of cancer, are linked to retroviruses.

Low-incidence cancer-causing retroviruses lack inserted host information. Instead, it seems that they alter the expression of potentially carcinogenic host genes, which in turn results in cancer. Retroviruses incorporate proviral DNA into the chromosomal DNA of their host during the course of their regular life cycle. Integrations take place across numerous locations. Although most integrations are benign, some can cause cancer. Many of these seem to encode tyrosine phosphorylating protein kinases.
