The human body attempts to cool down during exercise by producing sweat, while a dog's body attempts to cool down by panting
.......is secreted into the bloodstream, whereas _____ is secreted into mucus such as gastrointestinal fluid, colostrum, saliva, tears, and sweat:
a. Monomeric IgM; pentameris IgM
b. Monomeric IgA; dimeric IgA
c. Monomeric IgA; dimeric IgM
d. Dimeric IgA; monomeric IgA
Answer:
b. Monomeric IgA; dimeric IgA
Explanation:
IgA is a class of antibodies that are found mainly in body secretions. In sweat, tears, saliva, mucus, breast milk, and gastrointestinal secretions, IgA is secreted as a monomeric antibody. Smaller quantities of this class of antibodies are also present in blood and lymph. However, IgA is present in a dimeric form in the bloodstream. It makes up 10–15% of all antibodies in the blood. The main function of this class of antibodies is to give localized protection of mucous membranes against bacteria and viruses.
Dr. marshall demonstrated that gastric ulcers are caused by a bacterium by using Koch’s postulates.
Koch’s postulates are four standards created to confirm a causative relationship between a microorganism and a disease. Koch’s postulates were formulated in 1884 by Robert Koch and Friedrich Loeffler. Koch’s postulates include;
- the microorganism must be found in every cases of the disease.
- the microorganism must be isolated from the diseased host and grown in pure culture
.
- the cultured microorganism must cause the disease when introduced into a healthy laboratory animal
.
- the microorganism must be re-isolated from the new host and identified to be the same as the original causative agent
.
Answer:
thidium monoazide
Explanation:
"This chemical is known to penetrate only into "dead" cells with compromised cell membrane integrity. Subsequent photoinduced cross-linking was reported to inhibit PCR amplification of DNA from dead cells." Is what i found off of online :3
