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.

6) How does an offspring of a mushroom or mold (asexual reproduction) compare to its parent?

Verizon [17]

A mushroom or a mold commonly reproduces asexually by the formation of spores. Spores are produced in the sporangium through mitosis involving only one parent. They are released from the parent and germinate into new a mushroom or a mold. The offspring are genetically identical to that parent because their formation do not involve meiosis and fertilization. Spores allow fungi to expand their distribution and colonize new environments.

Suppose that a person takes a fall while hiking and develops tetanus when the pathogen enters through an open wound in their arm

qaws [65]

The tetanus infection is considered to be a Droplet infection.

<h3>What is Tetanus?</h3>

Tetanus is a neurological disease which is characterized by the occurrence of spasms in the muscle.

Tetanus can be caused if initial care does not take place after the wound occurs and therefore, it is very important to immediately take care of the wound.

To treat the wound tetanus immunoglobulin and tetanus toxoids are given to the person, however, it is necessary to give the two injections using different syringes and at different sites, because the immunoglobulin can cause neutralization fo the toxoid.

Thus, this could be the answer.

Neville has low blood pressure and his pituitary started producing a homorone to maintain water balance his blood pressure event

ivanzaharov [21]

Answer: The options are missing in the question,the options are;

A) Positive feedback will stop the release of this hormone.

B) Positive feedback will speed up the release of this hormone.

C) Negative feedback will speed up the release of this hormone.

D) Negative feedback will stop the release of this hormone.

The correct answer to the question is option D

NEGATIVE FEEDBACK WILL STOP THE RELEASE OF THIS HORMONE.

Explanation: The hormone the will be produced is known as Antidiuretic hormone (ADH).it is otherwise known as VASOPRESSIN.It is secreted by the posterior lobe of the pituitary gland.

The main effect of Antidiuretic hormone is to reduce urine output,(diuresis is the production of large amount of urine). Antidiuretic hormone acts in the distal convulated tubules and the collecting ducts of the nephrons of the kidneys,it increases their permeability to water and more of the glomerular filtrate is reabsorbed. Antidiuretic hormone secretion is determined by the osmotic pressure of the blood circulating to the osmoreceptors in the hypothalamus.

As osmotic pressure rises,for example as a result of dehydration, secretion of Antidiuretic hormone increases. With this,there is Increased reabsorption of water reducing the amount of urine produced.This implies that more water is retained in the body making the rise in the osmotic pressure of the blood to be low,for example,after a large fluid intake, secretion of Antidiuretic hormone is reduced,less water is reabsorbed and more urine is produced.

At high concentrations,for example after severe blood loss, antidiuretic hormone causes smooth muscle contraction, especially vasoconstriction in small arteries.this has a pressor effect,raising systemic blood pressure.
