ANSWER:
Cytokines, Chemokines, Leukocytes, Neutrophils, Macrophages, and Dendritic cells are all involved
EXPLANATION:
On the incidence of Streptococcus, the immune system activates a complex response that relies basically on the instatement and activation of macrophages, neutrophils, and dendritic cells.
These activities will only occur on the activation of innate immune responses through workout between pattern recognition receptors (PRRs) with streptococcus derived pathogen-associated molecular patterns (PAMPs).
Moreso, cytokines and chemokines (well known are IL-1β and CXCL1 respectively) produced by macrophages and dendritic cells on exposure to Streptococcus, elicits neutrophil.
Neutrophils then produces antimicrobial proteins, reactive oxygen species (ROS) and sometimes neutrophil extracellular traps (NETs), all these for the bacterial infection control.
Scientists find most deep-ocean trenches in the Pacific. Example being the Mariana Trench.
A major disadvantage with molecular phylogeny is the difficulty in making assumptions in a species with variations in their phylogenies yet
they have the same genotype. The emergence
of horizontal gene transfer has also complicated molecular phylogenetics. Making
inferences on positional homology in different organisms is also difficult and complicated.
