How are leukocytes classified?

Leukocytes are classified based on the presence or absence of granules in their cytoplasm. They can be categorized as granulocytes (neutrophils, eosinophils, basophils) or agranulocytes (lymphocytes, monocytes). Additionally, they can be further differentiated based on their specific functions and surface markers.

B cells are primarily activated by the activities of A antigens B macrophages C helper T cells D antibodies E plasma cells?

Antibodies are produced by B lymphocytes. An antibody is a class of proteins produced by B lymphocytes, sometimes known as B cells. To neutralize diseases or foreign substances like poisons, these antibodies bind to them. For instance, an antibody can attach to a virus, preventing it from infecting a healthy cell and spreading. B cells can enlist the aid of other cells in the fight against an infected cell. Central BioHub offers thousands of B cells collected from patients and healthy donors for research.

What is the steps in PCR?

1. Denaturation (separation of two strands of DNA by temperatures of around 94 to 98 degrees Celsius)

2. Annealing (binding of DNA primer to the separated strands. Occurs at 50 to 65 degrees Celsius, which is lower than the optimal temperature of the DNA polymerases)

3. Elongation (elongation of the strands using the DNA primer with heat-stable DNA polymerases, most frequently Taq (Thermus aquaticus) or Pfu (Pyrococcus furiosus) polymerases. Occurs at over 70 degrees Celsius)

What body systems are affected by valley fever and if you have Hep C and Asthma what are the risk if you get valley fever?

At first only the lungs are affected. If not treated it can spread. Having Hep C and asthma will not make the likelihood of getting Valley fever more so. But Asthma can become worse. Hep C will only make a person feel worse. More and more cases are showing up in the dry SW.

Valley fever is a fungal infection caused by coccidioides fungi. It can cause fever, chest pain and coughing, among other signs and symptoms.

Two species of coccidioides fungi cause valley fever and are commonly found in the soil and can be stirred into the air by farming, construction and wind. The fungi can then be breathed into the lungs and cause valley fever, also known as acute coccidioidomycosis.

Mild cases of valley fever usually resolve on their own.

In more severe cases, doctors prescribe antifungal medications.

Valley fever is the initial form and can develop into chronic and disseminated coccidioidomycosis.
