First line of defense, the cells of the innate recognize and respond to pathogens in a generic and fast way and does not confer long-term or protective immunity. Recruitment of immune cells to the sites of infection and inflammation and activation of the complement system cascade.

Explanation:

Innate immunity is a defense system that you were born with and that protects you against all antigens. Innate immunity consists of barriers that prevent harmful materials from entering the body. These barriers form the first line of defense in the immune response. There are also phagocytic cells of the immune system which include: macrophages, neutrophils, and dendritic cells. The membrane receptors of those cells allow it to act on the recognition of danger signals and they are of the type TLR and PRR. These are Antigen Presenting cells which process the pathogens and display their antigens on their surface and takes it to B lymphocytes for the production of antibodies, which is part of the adaptive immune system.

This means that the cells of the innate recognize and respond to pathogens in a generic and fast way and, unlike the adaptive immune response, does not confer long-term or protective immunity to the host.

So, the main functions of the innate immune response include:

Recruitment of immune cells to the sites of infection and inflammation, through the production of chemical factors, including specialized chemical mediators, called cytokines.Activation of the complement system cascade to identify bacteria, activate cells and promote clearance of dead cells or antibody complexes.The identification and removal of foreign substances present in organs, tissues, blood and lymph, by leukocytes.The activation of the adaptive immune response through a process known as antigen presentation. Inflammation is one of the first responses of the immune system to infection or irritation. It is stimulated by the release of chemical factors and serves to establish a physical barrier against the spread of infection, and to promote the recovery of some damaged tissue following clearance from pathogens. Chemical factors produced during inflammation (histamine, bradykinin, serotonin, leukotrienes) sensitize pain receptors, cause vasodilation of blood vessels at the scene, and attract phagocytes, especially neutrophils.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

Plz fast biotechnology is a growing field of applied biology. many crops such as corn have been engineered to be resistant to herbicides. therefore farmers can spray these chemicals to kill weeds growing near the crop without worries of killing the crop itself how does this type of biotechnology work? a. by changing the genetic make up of the crops. b. by causing the crops to kill the weeds. c. by changing the type of crops used. d. by changing the location of the crops.

What is a limitation of using a chemical formula, such as c6h1206, to represent a compound? the chemical formula does not show the types of elements that make up the compound. the chemical formula does not show how the atoms are connected to one another the chemical formula does not show the number of atoms of each element in a molecule. the chemical formula does not show the chemical symbols of the elements in the compound
