The complement system is a biological barrier of the immune system

The complement system is a group of proteins in the blood that detect pathogens that have entered the body.

The complement system can cause inflammation , the swelling of a part of the body accompanied by redness, swelling, and the pain as a response to infection.

1. The right answer is biological.

The nonspecific response, which constitutes innate immunity, works by not taking into account the type of disease it is fighting. It is the first line of defense against an infection. Several types of mechanisms intervene during this response:

* physical barriers (skin, mucous membranes, tears...)

* inflammation;

* cells of innate immunity:

* complement: it is a group of proteins that plays a role in immunity.


2. The right answer is proteins.

The complement system is a group of 25 known serum proteins, part of the innate immunity. Twelve (12) of these proteins are directly involved in the mechanisms of elimination of pathogens, the others finely regulate the activity of the former to avoid an autoimmune reaction.


3. The right answer is inflammation.

Inflammation is the body's stereotyped immune system reaction to external aggression (infection, trauma, burn, allergy, etc.) or internal (cancerous cells). Inflammation is a universal process, involving all tissues (called ubiquitous); it involves innate immunity as well as adaptive immunity.

Group the terms according to the subatomic particle they describe.
LiRa [457]

Answer:

This question is incomplete

Explanation:

This question is incomplete but the completed question can be seen in the document attached.

There are three main subatomic particles namely electrons, protons and neutrons. However, the question only discusses two of them; electrons (negatively charged) and protons (positively charged).

A. Found in all matter

Answer: They are <u>both</u> found in all matter since all matter are made up of atoms and all atoms have both protons and electrons (and even neutrons).

B. Negative charge

Answer: The subatomic particle with negative charge (as discovered by R.A Millikan) is the <u>electron</u>

C. Exists in the nucleus

The subatomic particles found in the nucleus are the <u>protons</u> and neutrons.

D. Attract opposite charges

They <u>both</u> (protons and electrons) attract opposite charges because they are of opposite charges and generally unlike charges attract.

E. Moves at extreme speed

Of the two subatomic particles mentioned, <u>electrons</u> move faster than protons because of there lighter mass when compared to the protons. However, the fastest subatomic particle is the neutrino.

F. Bound by strong force

The <u>protons</u> are bound by strong nuclear force which binds them to the nucleus of the atom.
