What is a pathogen?

A pathogen is an organism that causes disease in its host, and the severity of the disease symptoms is referred to as virulence

Pathogens, which include bacteria, fungi, protozoa, worms, viruses, and even infectious proteins known as prions, cause infectious diseases.

Chemical barriers to infection include enzymes in tears, saliva, and mucus that break down bacteria's surface.

Acid in sweat and stomach kills cellular pathogens, and semen contains anti-bacterial proteins (the fluid that contains male sperm).

Pathogens wreak havoc on their hosts in a variety of ways. The most obvious method is direct damage to tissues or cells during replication, typically through the production of toxins, which allows the pathogen to reach new tissues or exit the cells within which it replicated.

Thus, the correct option is D.

An individual's perception of health plays an important role in determining health outcomes. ... Those who perceive that stress affects their health may have an external locus of control, believing that their health is not in their control, but attributable to external circumstances.

Metabolic syndrome is a group of risk factors that includes high cholesterol, high blood pressure, high blood sugar levels, and abdominal obesity. These risk factors are often caused by poor diet and lack of exercise. Traditionally, these risk factors affect only adults and not younger populations. However, current studies show that adolescents and teenagers are developing metabolic syndrome.

Answers

Explanation:

It is a fact that adolescents and teenagers are facing metabolic syndrome nowadays. Since they are all using social media the most, the truth about this type of syndrom could be spread more on the internet and especially Instagram so everyone can see it. In that way, the young population will see how many problems it can cause and they will be a little careful about that stuff.

It is good also if someone also shows them what is the minimum that everyone can do in due to help themselves and then if they are interested and motivated, they can discover how it would be if they look for themselves like they should, with their maximum.

general types, each with a different action against pathogens:
Name them

Answers

Answer:

The leukocytes of innate immunity can be, according to their functions, leukocytes with phagocytic activity and natural killer leukocytes or NK.

Explanation:

Innate immunity is a natural and non-specific immune response of an organism, which implies an immediate response but does not extend over time. The innate cellular response includes phagocytes and natural killer cells or NK.

- Phagocytes or leukocytes with phagocytic function can identify and eliminate foreign agents generally, without discriminating between the type of agent. Macrophages, dendritic cells and neutrophils belong to this cell group.

- NK cells are able to eliminate cells in the body infected by microorganisms, as these cells are not recognized as their own due to changes in their cellular markers. Tumoral and virus-infected cells can be eliminated by NK. Basophils, eosinophils and mast cells belong to this group of NK cells.

The minimum amount of stimuli that can be detected by one of your senses, such as faintest of smells humans can detect is called the
a) extrasensory perception
b) sensory receptor
c) adaptation syndrome
d) absolute threshold

Answers

Answer:

The minimum amount of stimuli that can be perceived by the senses is called the absolute threshold (option d).

Explanation:

Absolute threshold implies the capacity of a sensory receptor to perceive very small stimuli and marks the beginning of the perception of a specific sense. This means that any stimulus whose intensity is less than the absolute threshold will not be perceived.

The capacity to perceive stimuli is individual, and for each person the absolute threshold is different, which is why there are people with a better sense of smell or a greater capacity to differentiate flavors. Repeated stimuli can cause the absolute threshold to increase, decreasing the capacity to perceive very small stimuli.

the other options are not correct because:

    a. Extrasensory perception is an unproven phenomenon that involves perceiving stimuli by senses other than the five already known.

    b. A sensory receptor is a structure capable of detecting stimuli and converting them into nerve impulses.

    c. The adaptation syndrome is more linked to stress and the presence of stressors.

Elroy was diagnosed with Lennox-Gastaut syndrome when he was 2 years old. Lennox-Gastaut syndrome is a severe form of generalized epilepsy that results in the frequent seizures. It is also associated with intellectual disabilities and developmental delays, likely due to the repeated neuronal insult from the seizures. After trying a number of different medications, the doctors have failed to find one that is able to control Elroy's seizures. Therefore, his doctor recommends that Elroy start on a ketogenic diet to severely limit the amount of carbohydrates in the diet. While this diet is thought to be fairly successful, it is important to calibrate carbohydrate intake precisely to avoid serious side effects. Therefore, Elroy and his parents are working closely with a dietician to ensure that he meets his minimum carbohydrate requirements for glucose-requiring tissues, while still limiting carbohydrates enough to prevent seizures, and simultaneously meeting the regular energy requirements for the rest of his body. When Elroy first starts this diet, his glucose levels decrease. What process increases in order to provide energy for glucose-requiring tissues?

Answers

Answer:

The process that increases to provide energy for glucose requiring tissues is Ketogenesis.
