Name two component of semen that are used for presumptive serological testing.
name and discuss the probable, presumptive and probable signs of pregnancy, What is Naegles rule and how is it used to calculate EDD. What is gravida and parity and define GTPAL with an example.
Why is it possible to identify many protozoa without the need for biochemical and serological testing? What are some of the beneficial protozoa? What chemical substance is present in viruses, but lacking in prions? Do prions replicate the way viruses do?
name the 3 constituent of biological stain that would identify semen
please help ASAP! 1. Serological testing is based on the fact that? All bacteria have the same antigens. Antibodies react specifically with an antigen and different bacterial species express different antigens. Only the human body makes antibodies against bacteria. Antibodies cause the destruction of antigens. Bacteria clump together when mixed with any antibodies and become visible to the naked eye. 2. Cholera is transmitted through fecal contamination of water. This type of transmission is known as? direct contact. indirect contact....
a) A component of a machine has to be replaced. Testing a sample of the component, it was determined that a ductile material was needed. ASTM A220 steel is available in two (2) grades. Grade 1 has a percentage elongation of 6% whereas Grade 2 has a percentage elongation of 4.5%. You are required to make a selection giving reasons for your choice. [3 marks)
What approach is used to diagnose typhoid? O Tissue sampling O Urine culture Serological antibodies O Sputum test
Two designs for a critical component are being investigated. During prototype testing, it was found that the time to failure is Weibull distributed with a minimum life of zero. Design A has Weibull parameters of β=2 and η=100 Design B has Weibull parameters of β=3 and η=100 hours. The component has a 10-hour guaranteed life. Assuming both component cost about the same. Which design should the manufacturer produce and why?
The central vulval precursor cells laterally inhibits two cells (presumptive lateral vulval precursors) on either side, from becoming central vulval precursor cells using Notch signaling. Therefore eliminating Notch signaling specifically from the two “presumptive” lateral vulval precursor cells will: A. result in 3 lateral vulval precursor cells B. result in 3 central vulval precursor cells C. result in no central vulval precursor cell D. result in 2 lateral vulval precursor cells E. none of the above
#5. Name the t test used in hypothesis testing to evaluate the mean observed in one sample. #9. Who determines the level of confidence for an interval conservative? #25. A researcher computes the following 95% CI = 12 to 24. What is the point estimate for this 95% CI?
Answer the question4 but don’t talk about these two test which
we used.1- sickle solubility testing and cellouse acetate
