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.
Mitochondrion. A mitochondrion (mitochondria, plural), is a membrane-enclosed organelle that is found in most eukaryotic cells. Mitochondria are called the "power plants" of the cell because they are the sites of cellular respiration, where they use energy from organic compounds to make ATP (adenosine triphosphate)
Answer: At least four pairs of alleles are involved in skin color, and there are nine (or more) shades of skin color. The bionomial expansion (a + b)6 can also be used to display the cross in Table 1, where the letter a represents the number of capital letters and the letter b represents the number of small case letters.
Explanation:
<span>In the nfpa 704 labeling system, a rating of 4 in any quadrant corresponds to t</span>he highest degree of hazard. Hazard
severity is indicated by a numerical rating that ranges from zero (0)
indicating a minimal hazard, to four (4) indicating a severe hazard.
