When you take a pain reliever like ibuprofen, it keeps injured or damaged cells from making and releasing prostaglandin. When the cells don't release this chemical, it means that the brain won't get the pain message as quickly or clearly.

Plate tectonics suggests that Earth's entire crust is composed of a number of large plates that are in constant motion relative to each other. Some plates are sliding under other plates, some are sliding past each other, others are pulling apart, and still others are colliding.
Answer:
A) Dendritic cells and macrophages, although they are also found in other cells that belong, or not, to the immune system.
B) The innate immune response
Explanation:
The immune system is equipped with specialized receptors for the detection of pathogens such as bacteria or viruses, which are called receptors that recognize patterns (PRRs). These proteins are a key element in the innate system and are expressed primarily in antigen presenting cells, such as <u>dendritic cells and macrophages, although they are also found in other cells that belong, or not, to the immune system.</u>
<u>
The innate immune response</u> begins with the recognition of highly conserved molecular structures and present in large groups of microorganisms called 'molecular patterns associated with pathogens' (PAMP). This recognition is done by the 'pattern recognition receptors' (RRP) of the host.
The best known bacterial PAMPs are:
Lipopolysaccharides (LPS)
Peptidoglucan
Lipoteic Acids
Mananas (Mannose
)
Bacterial DNA
Double stranded RNA
Glucans
These PAMP are essential for the survival and pathogenicity of bacteria.
They would use a microscope to test it out.
