The answer is B.
An inflammatory response is a nonspecific immune response. It is defined as a reaction of the body to injury or destruction of tissues and takes place in the following steps:
1. Tissue damage caused by injury or bacterial infection is detected.
2. Chemotactic factors and vasodilators are released.
3. increased capillary permeability and increased blood flow to the area occurs.
4. Migration of phagocytes to the site of infection rapidly occurs.
5. Special serum proteins and phagocytes attack and destroy bacteria.
6. Inflammation subsides once the invading pathogen is destroyed.
Answer: Option C) selective barrier that separates nuclear and cytoplasmic constituents, localizes chromosomes within the cell, and sequesters many of the mRNA processing activities from the cytosol.
Explanation:
The nuclear membrane is a double membrane surrounding the nucleus of eukaryotes. It consists of outer and inner membranes perforated by nuclear pores. Thus, it serves as a selective barrier between the nucleus and cytoplasm, also restricting post translational modification activities to the nucleus. As well, the nuclear envelope is absent in prokaryotes.
The factor responsible for the lifetime immunity against certain diseases like chicken pox and measles, that do not infect a person more than once is (c) the acquired immune response, because antibodies are developed from previous infections.
The acquired immune response is the specific type of immunity that develops for a certain type of pathogen. This immunity is achieved when the antibodies are received from an outside source such as vaccine. It is a more stronger type of immunity as it stays for a longer time, preferably for lifetime and also has memory.
Antibody is Y-shaped structure present inside the body. It is a compound formed to fight against any pathogen also called antigen. Antibody recognizes specific component on a pathogen and protects the body.
