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?
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
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

4. Name two tests not mentioned in this practical that can be performed on samples to confirm the identity of the haemoglobin variants and briefly state the principle of each test. (4 marks) 5.1) Explain what is meant by a qualitative globin chain defect. (2 marks)
A component is undergoing testing which involves being subjected to a steady stream of particles of ice. A constant stream of ice strikes the component horizontally at a velocity of 22 m s1 and bounces elastically. If 10 kg of ice strikes the component every minute, calculate the magnitude of the horizontal force exerted on the component by the ice. Give your answer in newtons to 2 s.f Force: N
