00- Describe how the following virulence factors contribute to disease: 1. The polysaccharide capsule of Streptococcus pneumonia 2. Type IV pili of Neisseria meningitides 3. Pseudomonas aeruginosa quorum sensing genes

1.The shorter the wavelength of visible light the Group of answer choices a, more photons it contains b, less energy absorbed by photosynthetic pigments c, reener the color d, greater the energy 2. The reason we breathe in oxygen is to assist in the production of Group of answer choices a, cell structures b, ATP c, Glucose d, Nitrogen   3. Why does a plant use the CAM or C4 pathway during photosynthesis? Group of answer choices a, To bind carbon dioxide and not use the C3 pathway in photosynthesis b, To bind Carbon dioxide to use later in the C3 pathway when carbon dioxide levels are low due to closed stomata c, Plants that use C4 and CAM do not do photosynthesis d, To use in the process of cell respiration when stomata are closed

85) For the virulence a. The H9N2 is more virulent than H5N1 b. The H9N2 is less virulent than H5N1 Hee c. The velogenic NDV is more virulent than H5N1 d. The lentogenic NDV is more virulent than H5N1.

74. Clinical case, young homeless man, HIV+. You are working at the community clinic when a young, HIV+, homeless man presents with fever, fatigue and a cough of 6 months duration. You Gram stain a sample of his sputum and examine with your microscope, you see faintly staining bacilli in cords. You next perform an acid-fast stain on the sputum and see red staining bacilli in cords. Question: The reason the pathogen did not stain well with the Grams stain is because of the thick hydrophilic capsule thick, waxy, hydrophobic cell wall O thick, hydrophilic cell membrane O thick layer of hydrophobic peptidoglycan
