prisoha [69]
<h2>False </h2>

Explanation:

The immune system develops integrated innate and adaptive modules that are pathogen type-specific and no single response can effectively control all types of pathogens

Both innate and adaptive immune system operate in cooperative and interdependent ways

Innate immune system is present since birth in an organism and is non specific in nature which means acts against all foreign antigens and molecules and provides first line of defense against pathogens

Adaptive immunity system is the acquired one which is capable of recognizing and selectively eliminating specific foreign antigens and is antigen specific which means can discriminate among different antigens; also has the ability to respond to various kinds of epitopes of pathogens

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.

Describe the relationship among atoms,molecules, matter
Vladimir [108]

Answer:

Atoms, molecules and matter are related because matter is made up of atoms. Molecules are atoms of more than two elements that are chemically bonded together. An atom is a certain element that becomes a  compound or molecule when bonded with other atoms. So matter is made up of one type of element or combinations of elements.
