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.

How does seed formation take place in plant? explain.​
neonofarm [45]

Answer:

Seeds are the result of plant reproduction. ... When pollen lands on the flower's stigma, it germinates and forms a pollen tube, which then quickly grows towards the plant's ovary. Once it finds an ovule, the pollen tube bursts to release sperm cells, which fertilize the ovule and initiate seed formation.

What function do plants have in the forest in the carbon cycle
statuscvo [17]
Plants absorb carbon dioxide,water and sunlight to make their own food,grow and release oxygen through photosynthesis. They're a huge part in keeping our air clean. The carbon becomes part of the plant. Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. When humans burn fossil fuels, most carbon enters the atmosphere as carbon dioxide.

1.If a DNA molecule has 40% Cytosine, what percent of it would be Adenine?
andrey2020 [161]

Answer:

The correct answer is -

1. Adenine - 10%

2. A-T and C-G always in DNA.

Explanation:

1. The total amount of all nitrogenous bases are equally 100% and which includes an equal amount of C and G and an equal amount of A and T in the DNA molecule.

So, Cytosine = 40%, Guanine= 40%

total = 80%

therefore, the A and thymine would be - 100 - 80 = 20

A+T = 20

A= 10, and, T = 10%

2. The complementary base pairing rule explains that DNA base pairs are Adenine always binds with thymine and cytosine bind with guanine only. Purine binds with pyrimidine always except - A-C or G- T.
