opportunistic pathogens question 4 options: a) cause disease in every individual. b) cause disease in compromised individuals. c)

Answers

Answer 1

Opportunistic pathogens cause disease in compromised individuals.

B is the correct answer.

Opportunistic pathogens are bacteria that, while typically causing no disease in healthy humans, can become virulent in immuno-compromised and unwell people. In recent decades, a number of bacteria that are often found in food have turned into opportunistic pathogens in both people and animals.

Opportunistic infections (OIs) are infections brought on by bacteria, fungi, viruses, or parasites that ordinarily do not spread disease but instead develop into a disease when the body's defence mechanism is compromised. Infections that are exceptionally severe yet are brought on by common organisms might also be considered OIs.

Many exoenzymes from pathogens are virulence factors. 1) True 2) False

Answers

True. Exoenzymes from pathogens are virulence factors which are molecules or compounds released by a pathogen that enables it to cause disease.

Exoenzymes, also known as extracellular enzymes, are proteins expressed and secreted by a pathogenic organism. These enzymes allow the organism to move, invade, and damage host cells. Exoenzymes also allow bacteria to break down host components to obtain nutrients, degrade host defenses, and protect the organism from host defenses.

Exoenzymes can cause disruption of the cell membrane and damage to cell organelles, leading to cell death. They can also induce inflammation which can lead to tissue damage. In addition, exoenzymes can inhibit the host’s immune response and interfere with the healing process. Thus, exoenzymes are important virulence factors that enable pathogens to cause disease.

the esophageal phase begins when the esophageal sphincter to allow ingested materials into the esophagus. listen to the complete question

Answers

The esophageal phase begins when the esophageal sphincter relaxes to allow ingested materials into the esophagus. This is an essential part of the swallowing process, facilitating the movement of food and liquid from the mouth to the stomach for further digestion.

The esophageal phase of swallowing begins when the upper esophageal sphincter relaxes to allow ingested materials to enter the esophagus. The upper esophageal sphincter is a ring-like muscle at the top of the esophagus that normally stays closed to prevent food and liquids from entering the airway. When we swallow, the muscles in the tongue and pharynx (throat) contract to move the food or liquid into the esophagus. At the same time, the upper esophageal sphincter relaxes to let the food or liquid pass through into the esophagus. From there, the food or liquid is moved down the esophagus by waves of muscular contractions (peristalsis) towards the stomach.

multiple choice question the rise in blood lactate that occurs during incremental exercise may be the cause of the alinear rise in the ventilatory threshold, because the carotid bodies that increase the threshold can be stimulated by a(n) blank .

Answers

The carotid bodies that rise to the end can be elicited by an increase in hydrogen ion levels.

Acute NaCl overload, according to the findings, activates carotid bodies, but not mannitol. We conclude that during acute NaCl overload, the carotid bodies contribute to increased sympathetic activity.

The primary peripheral chemoreceptors are the carotid bodies, which are triggered by hypoperfusion, low oxygen partial pressure, high carbon dioxide partial pressure, blood acidity, and oxygen partial pressure.

In conscious humans, we demonstrated that the injection of adenosine selectively stimulates the carotid body, resulting in a dose-dependent increase in minute ventilation and blood pressure while simultaneously lowering heart rate.

In a nutshell, reflex bradycardia and systemic vasodilatation will result from the stimulation of stretch receptors by an increase in carotid sinus blood pressure. During changes in posture, the baroreceptor reflex is also essential for maintaining heart rate and blood pressure.

According to these findings, hypoxic stimulation of the carotid bodies results in a dichotomous sympathetic response, which means that sympathetic discharge to the heart decreases while sympathetic discharge to the peripheral vasculature increases simultaneously.

19) Cell 1 demonstrate passive transport. 20) Because molecules moved from the higher-concentration side (intracellular space - 180mg) to the lower-concentration side (extracellular space - 20mg). 21) Cell 2 demonstrate active transport. 22) Because molecules moved from the lower-concentration side (intracellular space - 50mg) to the higher-concentration side (intracellular space - 60mg). 23) The student could test ATP

What are active and passive transport?

Active and passive transport are the two ways in which molecules can be transported from one side to the other of the membrane.

Passive transport occurs in favor of the electrochemical gradient, meaning that molecules move from the high-concentration side to the low-concentration side. This transport does not need energy to occur.

There are two types of passive transport,

Simple diffusion ⇒ molecules move though the membrane lipidsFacilitated diffusion ⇒ channel proteins mediate the molecules' pass

Active transport occurs against the electrochemical gradient, so it needs energy to happen. It carries molecules from a low-concentration side to a high-concentration side. Carrier proteins are involved in active transport.

There are two types of active transport:

Primary active transport uses energy from the ATP molecule. An example is the Na-K bomb. Secondary active transport uses energy from the electric membrane potential. Examples are the carriage of Na, K, and Mg metallic ions.

In the exposed example,

Cell 1

                     Intracellular concentration     Extracellular concentration

Before                                    180 mg                                 20 mg

After                                       100 mg                               100 mg                        

Before transport, the concentration was higher inside the cell than outside. After, the concentration is lower inside the cell than before and higher outside the cell than before. This fact means molecules moved from the cell interior forward to the exterior. The motion was from the more concentrated side to the less concentrated side and stopped when concentration was equal on both sides of the membrane. This is passive transport.

Cell 2

                     Intracellular concentration     Extracellular concentration

Before                                    50 mg                                 60 mg

After                                       20 mg                                  90 mg                      

Before transport, the concentration was higher outside the cell (60 mg) than inside (50mg). After, the concentration is even lower inside (20mg) the cell than before (50 mg) and even higher outside the cell (90 mg) than before (60mg).

This fact means molecules moved from the cell interior forward to the exterior. The motion was from the less concentrated side to the high concentrated side. This is active transport.

19) Cell 1 demonstrate passive transport

20) Because molecules moved from the higher-concentration side (intracellular space - 180mg) to the lower-concentration side (extracellular space - 20mg)      

21) Cell 2 demonstrate active transport

Answers

As the size (area) of the body exposed to cold immersion increases, the temperature of the immersion should decrease.

This is because a larger surface area of the body exposed to the cold water results in more heat being lost from the body, causing the body to feel colder and the immersion to feel warmer in comparison. When the body is exposed to cold, it responds by trying to conserve heat and maintain core body temperature. The body's first response to cold is to constrict blood vessels near the skin's surface, which reduces blood flow to the skin and conserves heat within the body's core. However, when a large area of the body is exposed to cold immersion, this response may not be sufficient to maintain core body temperature, and the body's temperature may drop.

In summary, the temperature of the immersion should decrease as the size (area) of the body exposed to cold immersion increases, leading to a greater loss of heat from the body and a greater drop in body temperature.

Answers

Based on the data presented, the statement that is true is "an increase in glucose triggers production of insulin." This is because at 15 minutes, the subject ate a high-carbohydrate candy bar which caused their glucose concentration to remain constant at around 6,000 mg for the first 28 minutes.

However, at around 28 minutes, the subject's glucose concentration began to rise, peaking at approximately 9,500 mg at 40 minutes. This rise in glucose concentration triggered the production of insulin, which began to rise at approximately 35 minutes, reaching a peak of 14,000 mg at around 50 minutes.

Insulin is a hormone that is released by the pancreas in response to an increase in glucose concentration in the blood. Its primary function is to lower blood glucose levels by stimulating the uptake of glucose by cells and the conversion of glucose to glycogen for storage in the liver and muscle cells.

The data shows that when glucose levels rise, insulin production is stimulated, and when glucose levels drop, insulin production decreases. Therefore, an increase in glucose triggers production of insulin, and not the other way around.
