How you can detect pathogen?
Pathogenic bacteria are those which cause disease. You can identify a link between a bacterium and a disease by isolating the bacterium in a statistically significant number of occurances of the disease. Proving the link is causative is more difficult, but could be done with a cohort study or in vivo experimentation. Probably the most well documented case in recent years is the proving of Helicobacter pylori as a causative agent of stomach ulcers.
If bacteria are exposed to a B cell in the spleen they will initiate a?
If bacteria are exposed to a B cell in the spleen, they will initiate an immune response. The B cell will detect the foreign antigens on the bacteria, leading to its activation and differentiation into plasma cells that produce antibodies to combat the infection. This is part of the adaptive immune response that helps the body to fight off pathogens.
Which nutrient is correctly paired with the indicator used to detect its presence?
Vitamin C - iodine solution is the indicator commonly used to detect the presence of vitamin C due to the color change reaction that occurs.
What test can be used to detect substance of emulsion?
A drop test can be used to detect the presence of an emulsion. Add a drop of the emulsion to water. If it disperses or forms a milky appearance, it indicates the presence of an emulsion.
What color is resazurin in the presence of oxygen?
Resazurin is pink in the presence of oxygen. It is used as an indicator to detect the presence of oxygen in cell cultures or microbiological media.
How do the immune cells discover intracellular pathogens?
All cells have specialized proteins on their surface that show a sampling of the contents of the cell to certain immune cells, which recognize these samples as self or foreign (i.e. intracellular pathogens) and kill infected cells.
What is An instrument that can detect the presence of an electric charge is a?
An instrument that can detect the presence of an electric charge is an electroscope. It typically consists of a metal rod with a lightweight metal or foil leaves attached, allowing them to move in response to the presence of electric charge. By observing the movement of the leaves, one can determine the presence and type of charge.
What is the objective of an electroscope?
The objective of an electroscope is to detect the presence of electric charge. It does this by indicating whether an object is charged or not through the movement of its components, such as the leaves or needle, in response to the presence of electric charge.
What is a coproantigen?
Coproantigens are antigens found in the feces of humans and animals. Coproantigens are being used to help detect intestinal diseases.
How do toll-like receptors work in the immune system to detect and respond to pathogens?
Toll-like receptors are proteins that recognize specific molecules on pathogens, like bacteria or viruses. When a toll-like receptor detects a pathogen, it triggers a signaling cascade that activates the immune response, leading to the elimination of the pathogen. This helps the immune system to quickly detect and respond to potential threats.
Will adrenaline give a positive xanthoproteic test?
No, adrenaline will not give a positive xanthoproteic test. The xanthoproteic test is used to detect the presence of proteins, not hormones like adrenaline. Adrenaline is a hormone that is involved in the body's fight-or-flight response, and it does not react in the same way as proteins do in the xanthoproteic test.
What is the pupose of m9 paper?
to detect the presence of liquid nerve and blister agents to detect the presence of liquid nerve and blister agents
Can ants detect the presence of sugar through their sense of smell?
Yes, ants can detect the presence of sugar through their sense of smell.
Can sniffer dogs detect the presence of cocaine?
Yes, sniffer dogs can detect the presence of cocaine through their keen sense of smell.
What protects mucosal barriers?
Mucosal barriers are protected by various mechanisms such as mucus production, antimicrobial peptides, IgA antibodies, and the presence of commensal bacteria that compete with pathogens for nutrients and space. Additionally, immune cells located within the mucosa work to detect and eliminate invading pathogens to maintain barrier function.

Does a receptor detect change in the environment?
Yes, receptors are specialized cells or proteins that detect changes in the environment or within the body, such as changes in temperature, pressure, or the presence of chemicals. They transmit this information to the nervous system for further processing and response.
