Is the results of tissues of organisms at successively higher levels
Answer:
The diagnostic results and history findings that correlate with aplastic anemia are: White blood cell (WBC) count being less than 1,000/µL (1 ×109/L)
, a platelet count of 50 ×103/µL (50 ×109/L)
, recent bout with mononucleosis viral infection
, and completed chemotherapy for leukemia in the past year.
Explanation:
<u>Aplastic anemia occurs when the body isn't producing enough blood cells, which leads to fatigue and a higher risk of infections and unstoppable bleeding.</u>
The most common form of aplastic anemia <u>occurs when the immune system attacks the stem cells in the bone marrow</u>, which can happen when: a) one is exposed to toxic chemicals, b) one went through chemotherapy, c) having an autoimmune disorder, or d) one suffered from a viral infection.
Answer:
A. Prions do not contain genetic information, which is affected by ionizing radiation.
B. Denaturants may affect the tertiary structure of prions.
C. Prions are proteins.
Explanation:
Prions are the proteinaceous infectious particles that cause many degenerative diseases of neurons in both animals and humans. They consist of only protein and no DNA or RNA. Due to the absence of DNA or RNA as genetic material, these infectious particles are resistant to ionizing radiation. Ionizing radiations affect nucleic acids of pathogens to destroy them.
Denaturation of proteins affects their secondary and tertiary structures and leave them non-functional. Denaturation may be caused by changes in temperature, pH, disturbance of hydrogen bonds, etc. Therefore, to destroy prions, they need to be denatured.
